INTRODUCTION

1.1 Introduction about CompanyGALLIUM Industries Ltd.was established in 1985 by qualified and experienced professionals tocater tothe sophisticated equipment requirements of the Tube Industry worldwide. During this period tube plants available in the country were either being imported from USA, Germany and other advanced countries, or they were being locally fabricated which could not match the ever growing demands of the Tube Industry.It wasGALLIUMS MISSION to cater to the Global Tube Industry with the STATE OF THE ART Equipment, continuously develop the international technology and then cater to the market. With this mission the company started supplying complete tube plants to the major tube producers in the world.GALLIUMinitiated a new era in the field of tubes produced in India. The first mill manufactured byGALLIUMwas for 100 m/min. line speed with sophisticated entry line and computerised length control system for the flying cut off. Since then company has successfully supplied mills with line speed 150 m/min. or more.In the International frontGALLIUMmanufactured equipment are working in 29 countries including developed countries like USA, UK, Japan, Australia, Brazil, Egypt, Malaysia, China, Taiwan, Thailand , Oman, Jordan, Zimbabwe, Pakistan and many other countries. A number of repeat orders have been received from these companies.GALLIUMis amongst a very few companies in the world who can offer complete Tube Plants and services including all toolings and turnkey solutions by providing plant engineering for all utilities and auxiliary equipment.NTPC Limited(formerly known asNational Thermal Power Corporation Limited) is a Central Public Sector Undertaking (CPSU) under the Ministry of Power, Government of India, engaged in the business of generation of electricity and allied activities. It is a company incorporated under the Companies Act 1956 and a "Government Company" within the meaning of the act .The headquarters of the company is situated at New Delhi. NTPC's core business is generation and sale of electricity to state-owned power distribution companies and State Electricity Boards in India. The company also undertakes consultancy and turnkey project contracts that comprise of engineering, project management, construction management and operation and management of power plants. The company has also ventured into oil and gas exploration and coal mining activities. It is the largest power company in India with an electric power generating capacity of 42,964 MW.Although the company has approx. 18% of the total national capacity it contributes to over 27% of total power generation due to its focus on operating its power plants at higher efficiency levels

1.2Introduction about Project

Payroll Management is a distributed application, developed to evaluate the performance of employees working in any organization. It maintains the information about a company, personal details of their employees, also the project details assigned to particular developer. The application is actually a suite of applications developed using Java.It is simple to understand and can be used by anyone who is not even familiar with simple employees system. It is user friendly and just asks the user to follow step by step operations by giving him few options. It is fast and can perform many operations of a company.This software package has been developed using the powerful coding tools of JAVA at Front End and Microsoft Access at Back End. Because of the Visual features, the software is very user friendly. The package contains different modules like Contacts, Search for property and other useful Links. This version of the software has multi-user approach. For further enhancement or development of the package, users feedback will be considered.This project basically deals with five modules and their further sub modules. First module is the employee module into which we can enter employee details such as his name, address, phone number, his basic salary and many more. After that we can view the details further by using the employee id, and we can modify the details also. Similarly in department we have the details of all the HODs of the departments. Next comes the salary module in this we can view the salary issued to the employee. And can issue them to the employee we want to and can fix it to them.We can put the grades also in the grade module. Basically we create the grades in this with specified details. We can view the details accordingly. We can just enter the grade name and can view the details encapsulated in the grade. Other than this we can view the whole thing all together by getting into the view grade section.We can view the report also in this. It can be viewed in this easily that to which the monthly salary has been allotted and for which month. We can also look out those employees to whom the salary has not been issued and the further details also such as for which month it has not been issued. This is the basic overview of the whole projectAIM: To design the record book for employees of a firm.OBJECTIVE:The main objective of our project is to prepare a record of all emplyees working in a firm. Personal Record of all Employees. HODs of all Departments. Salary Calculation of all Employees. Grade Assigning to all Employees. Record of all Emplyees.

1.3Present state of the art

Presently salary calculation is done manually, it take so much of time to compose salary of all employees. It also takes very long time to make salary slip ready. Due to manual process some time it takes very long time, in turn it delays the salary distribution. This is a big problem to manage when salary is not generated in time. The other main problem is errors, even with double cross check here or there some errors will happen, this again create large problem. To solve all this the organization require very good software to take care of all these.

1.4Need of Computerization of System

The client uses MS Excel and maintains their records however it is not possible for them to share the data from multiple system in multi user environment, there is lot of duplicate work, and chance of mistake. When the records are changed they need to update each and every excel file. There is no option to find and print previous saved records. There is no security anybody can access any report and sensitive data also reports of summary. This Payroll Management System is used to overcome the entire problem which they are facing currently, and making complete atomization of manual system to computerized system.

1.5Proposed Software (What would s/w accomplish?)

The proposed software will solve all the problems they are facing now. This software is designed such way that it will generate the salary automatically every month in time. So there not much worries. This software also equipped with the facility of checking the employees to whom no salary has been sanctioned. The software built to generate individual pay slip and summary of the payroll.

SYSTEM ANALYSIS

2.1 Feasibility Study of s/w includes its types

Feasibility StudyOperational FeasibilityTechnical FeasibilityEconomical FeasibilityMotivational FeasibilityScheduled Feasibility

Feasibility study :Every project is feasible for given unlimited resources and infinitive time.Feasibility study is anevaluation of the proposed system regarding its workability, impact on the organization, ability to meet the user needs and effective use of resources.Thus when a new application is proposed it normally goes through a feasibility study before it is approved fordevelopment .Feasibility and risk analysis and related in many ways.If a project risk is great and feasibility of producing software is reduced.During the feasibility analysis in this project has been discussed below in the abovementioned topics.OperationalFeasibility:Feasibility of the working of the system after the installation inthe organization as mentionedin the feasibility analysis.

TechnicalFeasibility:Technical feasibility is frequently the most difficult areato ensure this stage.It is essential that the process of analysis and definition to be conducted parallel toan assessment of the technical feasibility.The consideration that is normally associated with technical feasibility includes the resources availability of the Organization where the project is to be developed and implemented.By taking these facts into consideration before developing the resourceavailability at Retail Outlet of Hindustan Petroleum was observed.As very limited resources are required for this project hence this project is considered feasible for development.EconomicFeasibility:An evaluation of development cost is weighted against the ultimate income or benefits derived from the developed system.There was no need of extra hardware and software for development of this project.Hence this project has economicallyjustified for development in thisorganization.MotivationalFeasibility:An evaluation of the probability that the organization is sufficient motivation to support thedevelopment and implementation of theapplication with necessary user participation, resources, training etc.The interest and support shown by the organization during the system study do not seem thatthe new system developed to have efficient support from theorganization.ScheduleFeasibility:An evaluation of the time neededfor the development of thisproject.The time schedule required for the development of this project is very important, since more development time effects machine time, costs and delays in thedevelopment of the othersystems.So the project should be complete within affixed schedule time as far as the organization is concerned.

Project Schedule:The major output of the production process is the project schedule.This is a graphic representation of the entire project related activities necessary to produce successful project.They allow the project manager to efficiently coordinate and facilitate the efforts of the entireproject team for the liveproject.This project schedule dynamic in nature that will undoubtedly be modified as the project proceeds .Without the master schedule the effective project control would be virtually impossible.If the schedule does not exist it is impossible to accurately estimate the project status.Projects that are not complete within the time frame established by the master schedule almost invariably exceed planned costs. The most complaint is that production takes too much timeand costs too much money .For schedule to be effective, itmust process several major characteristics:-Understandable by those who will use it.Sufficient detail to be provide on thebasis of measurement and control of project progress.Capable of highlighting critical tasks.Flexible and easilymodifiable.Confirm to availableresources.

Compatible with the system available inthe organization.

2.2Analysis Methodology (Types)

Descriptive Exploratory Inferential Predictive Causal Mechanistic

1.Descriptive(least amount of effort):The discipline of quantitatively describing the main features of a collection of data. In essence, it describes a set of data.- Typically the first kind ofdata analysisperformed on a data set- Commonly applied to large volumes of data, such ascensus data-The description and interpretation processes are different steps- Univariate and Bivariate are two types of statistical descriptive analyses.-Type of data set applied to:Census Data Set a whole population

2.Exploratory: An approach toanalyzing datasets tofind previously unknown relationships.- Exploratory models are good for discovering new connection.- They are also useful for defining future studies/questions- Exploratory analyses are usually not the definitive answer to the question at hand, but only the start- Exploratory analyses alone should not be used for generalizing and/or predicting- Remember: correlation does not imply causation-Type of data set applied to:Census and ConvenienceSample DataSet (typically non-uniform)- a random sample with many variables measured

3.Inferential: Aims to test theories about the nature of the world in general (or some part of it) based on samples of subjects taken from the world (or some part of it). That is, use a relatively small sample of data to say something about a bigger population.- Inference is commonly the goal of statistical models- Inference involves estimating both the quantity you care about and your uncertainty about your estimate- Inference depends heavily on both the population and the sampling scheme-Type of data set applied to:Observational, Cross Sectional Time Study, and Retrospective Data Set the right, randomly sampled population

4.Predictive: The various types of methods that analyzecurrent and historical facts to make predictions about future events. In essence, to use the data on some objects to predict values for another object.- The models predicts, but it does not mean that the independent variables cause- Accurate prediction depends heavily on measuring the right variables- Although there are better and worse prediction models, more data and a simple model works really well- Prediction is very hard, especially about the future references-Type of data set applied to:PredictionStudy DataSet a training andtest dataset from the same population

5.Causal:To find out what happens to one variable when you change another.- Implementation usually requires randomized studies- There are approaches to inferring causation in non-randomized studies-Causal models are said to be the gold standard for data analysis-Type of data set applied to:Randomized Trial Data Set data from a randomized study

6.Mechanistic(most amount of effort):Understand the exact changes in variables that lead to changes in other variables for individual objects.- Incredibly hard to infer, except in simple situations- Usually modeled by a deterministic set of equations (physical/engineering science)- Generally the random component of the data is measurement error- If the equations are known but the parameters are not, they may be inferred with data analysis-Type of data set applied to:Randomized Trial Data Set data about all components of the system

2.3Choice of Platforms s/w & h/w

Front End:

The programming has been done using the language Java. It is Sun Microsystemss strategic language for platform independent programming. It is easy to use, efficient and flexible. This language is preferred because one can build a program using this object oriented and platform independent programming with less effort than with any other programming language. Its a natural language for building database applications, owing to the level and sophistication of the tools included with the language.

Back End:

Microsoft Access is one of the leading database management systems available on the market today. It is easy to use and administer, and it comes with tools and wizards that make it easy to develop applications. The database itself has been redesigned to automatically perform many tuning functions, leaving you free to focus on most important tasks.

Platform Used:

The Payroll Management System is targeted at Microsoft Windows platforms.

The Java Architecture:

Javas strength comes from its unique architecture. The Java needed a language that was above all, simple for the programmer to use. Yet in order to create reliable network applications, Java needed to be able to run securely over a network and at the same time, work on a wide range of platforms. Java fulfills all of these goals and more.

Working of Java:

As with many other programming languages, Java uses a compiler to convert human-readable source code into executable programs. Java compiler generates architecture-independent byte codes. The byte codes can be only a Java virtual machine, which is an ideal Java architecture, usually implemented in software rather than hardware. The compilation process is illustrated as under.

Java Source CodeJava Compiler Java Byte codes

Java Features:

The major characteristics that make Java such powerful development tool are its security, open standards, memory management, object oriented, multithreading and its distributed and dynamic characteristics.

Simple

Java was designed to be the easy for professional programmer to learn and use effectively. If one already understands the basic concepts of object oriented programming, learning Java will be even easier.

Robustness

The multiplatform environment of the Web places extraordinary demand on a program, because the program must execute reliably in a verity of systems. Thus the ability to create robust programs was given a priority in the design of Java. To better understand how Java is robust, consider two of the reasons for program failure, memory management mistakes and mishandled exception conditions (i.e. run time error). Memory management can be difficult, tedious task in traditional programming environments. For example in C/C++, the programmer must manually allocate and free all dynamic memory. This sometimes lead to problems, because programmer will either forgot to free memory that has been previously allocated or, worse, try to free some memory that another part of their code is still using. Java virtually eliminates these problems by managing memory allocation and dallocation, because java provides for you. Exceptional conditions in traditional environments often arises in a situation such as division by zero or file not found and thy must be managed with clumsy and hard-to-hard construct.

Security Features

Security is probably the main problem facing Internet developers. Users are typically afraid of two things: confidential information being compromised and their computer systems being corrupted or destroyed by hackers. Javas built in security addresses both of these concerns. Java built-in security measures ensure java programs will operates within the rules of the VM & prevent untrustworthy programs from accessing system resources.

Open Standards/Platforms Independence

Today, java VMs are available for more than a dozen diff. Hardware and Operating system combination. The exciting aspect of javas cross-platform capability is that java class files do not need to be compiled for each platform in advance. The same compiled java program will work on the PC, Macintosh & every other platform that runs a java VM. A java application we write on our system today should run on every supported platform, even those do not exist yet. This reduces the development time by a very big factor.

Distributed and Dynamic

In the windows operating systems, parts of programs can be placed into Dynamic link libraries so that they can be shared and loaded Dynamically; i.e. when the program is running. The operating system does the final stage of linking at execution time. Using shared DLL (Dynamic Link Library) saves memory and improves the modality of the software.Java takes Dynamic Libraries a step further. The VM class loader fetches class files from the network, as well from the disk, providing location transparency, making java applications distributed as well as Dynamic.

Object-Oriented

Object Oriented Programming (OOP) is a way to software that is reusable, extensible & maintainable. Java is an object-oriented language that is it has facilities for OOP incorporated into the language. In OOPs it attempts to break a problem into its component parts. The solution focuses on these independent objects and their relationship to other objects.

Multithreading

A single-threaded application has one thread of execution running at all times, all such programmers can do only one task at a time. If a single threaded program need to perform a task that will take several-several minutes. E.g. downloading its user-interface will usually become unresponsive while the task is in progress. A multithreaded application can have several threads of execution running independently and simultaneously. Multithreading is commonly used to perform the following functions. Maintaining user-interface responsiveness:If our application needs to perform a time consuming task, we can use multiple threads to prevent our user interface from becoming unresponsive while the task is in progress. If our program will be downloading information from the Internet, we can create a separate thread for the Download routine. This will keep our user-interface running at nearly full-speed while the Download is in progress.

Simple Multitasking: Multitasking allows us to run multiple instances of a process quit easily. The Downloading routine just mentioned can be extended so that the program can transfer multiple files simultaneously and still will keep the user interface well behaved. All we need to do is create another thread for each file to Download. Building Multi-user Applications: Multithreading is often used when building server applications. Server applications wait for request to arrive and then establish conversations with the requester. It is much easier to write a routine that handles a single conversation and spawns multiple copies of that routine than it is to write a piece of code that handles multiple conversations at once. Multiprocessing:Many operating system support machines with multiple processors. Most these system are unable to break a single thread of execution into multiple pieces for execution on diff. Processors. By breaking an application into diff. Threads, it is possible to make the best use of processing power.

Java synchronized keyword can be used to prevent two threads from entering the same critical block of code at the same time. This is vital because some program steps t need to be made together as one atomic group.

Java Packages

Java packages simply collect classes on more pragmatic basis. Classes with related functionality are bundled together in same packages, whether they share code, data, or neither. In addition to their obvious structuring benefits packages use namespace partitioning, which means that every class contained in a package has a unique name that cannot conflict (collide) with class name defined elsewhere.Since packages give an easy handle on the entire hierarchy, they will guide to explore the java class hierarchy. The java 1.2 releases have about 60 java. * packages. The most commonly used packages are: Package java.lang contains the main language support classes. These with object wrappers, strings, multithreading, and related areas. Package java.util contains language support classes of more utilitarian nature. These include collection and calendar classes, as well as some abstract design codified by the interfaces comparator, iterator and observer. Package java.io provides device-independent file and steam I/O service. Package java.awt hides the bulk of all graphical classes. Because it contains javas abstract window tool kit (AWT), contained in java.awt and 12 sub packages, the package should really be considered as the heart of the entire hierarchy. Package java.net combines the classes supporting low-level Internet programming plus pluggable look-and-feel. Package javax.swing combines the classes for interfacing in a graphical manner. Package java.sql provides the classes & methods for database connectivity.

MICROSOFT ACCESS (BACK END):A database is a collection of information stored somewhere for easy organization and exploration. Databases are used in various situations such as keeping a record of friends, registering employees job attendance, counting the number of students in a classroom and keeping a record of their grades. This means that we have been using databases all our life. We are going to learn how to use the computer to create and exploit databases. We will use Microsoft Access. Learning how to use Microsoft Access and some programming is just a matter of applying your already tremendous knowledge on information storage and retrieval. Microsoft Access is a software product used for desktop database applications. You can use it for personal stuff, for home, or for your business/company

2.3.1Software used

The Java Development Kit (JDK):

The JDK is original Java Development environment for many of todays Java professionals. JDK is considered to be the reference implementation of Java. If the application is build and tested with JDK, it should run on any third party implementation such as in web browser, development tools or device-specific VMs. The JDK can create a display graphical application, but the JDK itself has a somewhat primitive command-line interface. The JDK programs are run by typing the command into command shell window. The JDK consists of a library of standard classes and collection of utilities for building, testing, and documenting java programs. The core AP include some important language constructs as well as graphics, network and file I/O capabilities.JDK UtilitiesThe following utilities of JDK are usedJava: The Java compiler. Converts java source code into byte code.Java: The Java Interpreter. Executes Java application byte codedirectly from the class

Building Application With JDK

After the JDK is installed, its time to take it for a test drive. The Java application is completed, executed, disassembled, documented, and interfaced to the C Language.

Java Application Source CodeJava source code can be written with simple text editor. Note pad can also be used. Most of source code is written in Microsoft Developer Studio. The codes defined the Java classes, which contains the method main(). When the Java interpreter tries to execute the class it will look for the method main(). The VM will execute this function to run the program. The name of Java source file is not arbitrary; it must be the same as the name of the public class defined in each file. If no public class is defined in java source file, the name of the file can be anything. Now Java program is ready to compile.

Using Java c

The Java c compiler converts the Java source code into Java byte code, which can be executed by Java. If the Java code is acceptable to the compiler, the .Java file, the file .class contains the byte code that can be executed by Java VM on any platform. The name of classes and methods and method used by the class file must be stored in byte code in order to access those classes and methods on the destination system.Using java

After compiling, the program is run with java interpreter by entering following commands. Java program_name.The interpreter has many command line options, most of which are function likely to be used by advanced java programmers. A prifiler is used to analyze howmuch time a program spends in each part of code. The use of prof option of the interpreter with the command.Java-prof program_nameThen a file called java.prof will be created. This file shows how many times each method is called and how many milliseconds are spending in executing each one.

gui swings:A Graphical User Interface (GUI) is a visual paradigm which allows a user to communicate with a program in an intuitive way. Its main features are widgets (aka controls) and event driven activities. Clients expect a graphical interface in an application.Java has two GUI packages, the original Abstract Windows Toolkit (AWT) and the newer Swing. AWT uses the native operating system's window routines and therefore the visual effect is dependent on the run-time system platform. But this is contrary to the concept of having a virtual model. Swing allows three modes: a unified 'Java' look and feel [the default], the native platform look, or a specific platform's look. Swing is built on the original objects and framework of AWT. Swing components have the prefix J to distinguish them from the original AWT ones (eg JFrame instead of Frame). To include Swing components and methods in your project you must import the java.awt.*, java.awt.event.*, and javax.swing.* packages.

Containers, Frames and Content Panes:Containers are widgets (GUI controls) that are used to hold and group other widgets such as text fields and checkboxes. Displayable frames are top-level containers such as JFrame, JWindow, JDialog, JApplet and JInternal Frame which interface to the operating system's window manager. Non-displaying content panes are intermediate containers such as JPanel , JOptionPane , JScrollPane, JLayeredPane, JSplitPane and JTabbedPane which organize the layout structure when multiple controls are being used . JWindow is an unadorned container that has been superceded for the most part by JDialog. However it does provide a useful container for a splash screen.

JFrame and JPanel:

JFrame is the most commonly used top-level container. It adds basic functionality such as minimize, maximize, close, title and border to basic frames and windows. Some important JFrame methods are: setBounds(x,y,w,h), setLocation(x,y), setSize(w,h), setResizable(bool), setTitle(str), setVisible(bool), isResizable() and getTitle(). The set DefaultCloseOperation (constant) method controls the action that occurs when the close icon is clicked. Normally the constant used is JFrame.EXIT_ON_CLOSE.JPanel is the most commonly used content pane. An instance of the pane is created and then added to a frame. The add() method allows widgets (GUI components) to be added to the pane.

Event Listeners:

GUIs are event-based. That is they respond to buttons, keyboard input or mouse activities. Java uses event listeners to monitor activity on specified objects and react to specific conditions. . For techniques on organizing many different events in larger projects, view advanced event listeners.The first step in adding a basic button push event handler to the above example is to import awt.event.* which contains all of the event classes. Next add the phrase implements ActionListener to the class header. Register event listeners for each button widget using the addActionListener (this) method.

SYSTEM DESIGN

3.1 Design methodology

A software require specification document tells us what a system does and becomes input to the design process. The purpose of design phase is to produce a solution to problem given SRS document.

SOFTWARE REQUIREMENT SPECIFICATION

Software Requirement Specification (SRS) Document

The SRS is a specification for a particular software product, program or a set of program that perform certain functions in specified environment. The two scenarios entirely different purpose for the document. First case SRS is used to define the needs and expectations of the user. The second case, SRS is written for different purpose and serve as a centre document between customers and develop.Nature of SRS: -The basic issues that SRS writer shall address the following.1.Functionality: - What the software supposed to do?2. External Interface: - How does the software interact with people, the system hardwareand other software?3. Attributes: -What re the considerations for portability, correctness, security, reliability etc.?

Characteristic of a good SRS An SRS should be0. Correct0. Complete0. Consistent0. Verifiable0. Modifiable0. TraceableA well-designed, well-written SRS accomplishes four major goals: It provides feedback to the customer. An SRS is the customer's assurance that the development It serves as a product organization understands the issue or problems to be solved and the software behavior necessary to address those problems. It decomposes the problem into component parts. The simple act of writing down software requirements in a well-designed format organizes information, place borders around the problem, solidifies ideas and help break down the problem into its component parts into an orderlyfashion. It serves as an input to the design specification. As mentioned previously, the SRS serves as the parent document to subsequent software design specification and statement of work. Therefore the SRS must contain sufficient detail in the functional system requirement so that a design solution can be devised. Validation check. The SRS also serves as a parent document for testing and validation strategies that will be applied for the requirements for verification.SRS are typically developed during the first stage of "Requirements Development" which is the initial product development phase in which information is gathered about what requirements are needed or not. This information gathering stage can include onsite visit, questionnaires, surveys, interviews and perhaps a return-on-investment (ROI) analysis of the customer or client's current business environment. The actual specifications, then is written after the requirements have been gathered and analyze.

SRS INCLUDE:Several standard organizations (including the IEEE) have identified nine topics that must be addressed when designing and writing an SRS:1. Interfaces1. Functional capabilities1. Performance Levels1. Data Structure Elements1. Safety1. Reliability1. Security/Privacy1. Quality1. Constraints

TABLES:

Mainly, in this project we have four tables that are employee table, department table, salary table and grade table. After filling all the enteries the detail of all the employees are ready.STATUS: Working

AREAS OF APPLICATION: For Small Scale IndustriesTARGET USERS: Large scale version can be implemented in both small scale & medium scale.ADVANTAGES: 1. Cost effective 2. Simple to operate

Design ProcessThe computer system design process is an exercise of specifying how, the system will work. It is an iterative process, which is based on what the system will be do as shown in the feasibility report.Mainly, following five parts have been included in the system design processOutput DesignThe starting point of the design process is the proper knowledge of system requirements which will normally be converted in terms of output.

Input DesignOnce the output requirements have been finalized, the next step is to find out what data need to be made available to the system to produce the desired outputs. The basic documents in which these data are available need to be identified. If necessary, these documents may have to be revised or new documents may have to be introduced.File DesignOnce the input data is captured in the system, these may to be preserved either for a short or long period. These data will generally be stored in files in a logical manner. The designer will have to devise the techniques of storing and retrieving data from these files.Procedure DesignThis step involves specifications of how processing will be performed. In this, there are two aspects: Computer ProcedureThe computer procedure will specify what functions will be carried out on computer, what will be different programs and in what sequence the programs will be run. Non-computer procedureThe non-computer procedure will specify the manual procedures for feeding input data, receiving outputs etc. Control DesignThe control design indicates necessary procedures which will ensure correctness of processing, accuracy of data, timely output etc. this will ensure that the system is functioning as per plan. Development and Deployment DesignMajor responsibilities include system Requirement Study, Preparing System Design Document, Preparing the Program (Form) Specs, Peer Review of the Specs, Implement Quality procedures as per the QMS Document, Documentation of SRS Revalidation & Design Documents, thorough grasping of the user functionality and applying, approving the same in the project, Developing, Testing & Debugging of Forms, User Training and Implementation of the module. INPUT DESIGN(Introduction)Once the analysis and design of the system has been done, it would be necessary to identify the data that are required to be processed to produce the outputs. Input is one of the most expensive phases of the operation of a computerized system and creates sometimes a major problem. Different type of problem with a system can usually be traced back to faulty input design method needless to say, therefore, that the input data are the lifeblood of a system and have to be analyzed and designed with utmost care and consideration. Input design features can ensure the reliability of the system and generate correct reports form the accurate data. The input design also determines whether the user can interact efficiently with the system. Elements of Input DataInaccurate input data are the most common cause of errors in data processing. Errors entered by data entry operators can be controlled by input design. Input data are collected and organized into groups of similar data. Once identified, appropriate input media are selected for processing. Input DataThe goal of designing input data is to make data entry as easy, logical and error free from errors as possible. In entering data, operators need to know the following: The allocated space for each field. Field sequence, which much match that in the source document. The format in which data fields are entered for example, filling out the date field is required through the edited format mm/dd/yy. When we approach input data design, we design the source document. Let us elaborate on each step.Source DocumentsSource data are captured initially on original paper or a source document. For example, a cheque written against an account is a source document. When it reaches the bank, it is encoded with special magnetic ink character recognition so that a reader that is part of the information system of the bank can process it. Therefore, source documents initiate a processing cycle as soon as they are entered into the system. Source documents may be entered into the system from punch cards, from diskettes, or even directly through the keyboard.A source document should be logical and easy to understand. Each area in the form should be clearly identified and should specify for the user what to write and where to write it.A source document may or may not be retained in the proposed system. Thus, each source document may be evaluated in terms of Its continued use in the proposed system .The extent of modification for the proposed system & Replacement by an alternative source document.

Input Design GuidelinesThe design of input play very significant role in getting the correct output. It covers al phases of input from creation of initial data (original recording) to actual entering the data to the system for processing. The input design is the link that ties the information system into the world of its users. Some features of design may vary depending on whether the system is batch-oriented or on-line. Here, we will discuss the various objectives of input design. They focus on: Controlling amount of input Avoiding delay Avoiding errors in data Avoiding extra steps Keeping the process simple

Each of the five objectives of input design is briefly discussed below: Controlling Amount of DataAn effective design controls the quantity of data for input for the following reasons:Firstly, data preparation and data entry operations depend on people. Since labor costs are high, the cost or preparing and entering data is also high. It is quite evident, then that reducing data requirements mean lowering cost through reduced labor expense.Secondly, the input phase of computing can be slow process and take many times longer than that needed by computers to carry out their tasks. In fact, the computer itself may sit idle until data is prepared and input for processing. By reducing input requirements, the analyst will speed the entire process from data capture to processing to provide result to users. Avoiding DelayWhen processing is delayed owing to data preparation or data entry, the cause is called a bottleneck. Avoid bottlenecks when designing input should always be one of the objectives of the analyst.

Avoiding Errors in DataThe third objective deals with errors. In one sense, the rate at which errors occur is dependent on the quantity of data. Since the lower the amount of data is inputted, there are fewer opportunities for the error to occur.Firstly, the analyst can reduce this number by reducing the volume of data dust must be entered for each transaction.Secondly, the analyst can also affect error rates of an operation through design. The manner in which data must be entered can reduce the chance of errors.Still, a third aspect of error control is the need to detect errors when they do occur. Checks and balances in the data entry programs, called input validation techniques, also detect errors input.OUTPUT DESIGN (Introduction)Presenting the data processed by a computer-based information system in an attractive and usable form has become very essential these days success and acceptance of a system to some extent depends on good presentation. Therefore, system analyst must know fully how to design output report in an attractive way. Many new output devices are being introduced in the market because of recent development in computer technology. System analyst must be aware of these new technologies and try to use these new output devices if possible. Currently, excellent graphic displays are widely available. Speech output systems are also fast emerging.There are three main reasons why outputs from the computer are required. They are: For communication to the persons concerned. For re-input to the computer for being connected with other data and further processing. For permanent storage.

Types of Output:Outputs of a system can take different forms. The most common are reports, displays on screen, printed forms etc. the outputs also vary in terms of their contents, type of stationery. Frequency and timing etc. besides, due consideration also need to be given as to who will use the output and for what purpose. All these points must be kept in mind while designing outputs so that the objectives of the system are met in the best possible way.

Outputs of a data-processing system can be placed into two categories: Application Output Operating Output

Application OutputThese are the outputs desired out of the system to meet its objectives. These are of three types: Output as a basis for decision-making. This type of output is generally required by management for decision-making purposes. Output as a requirement to meet a functional objective. Invoices, Excise Gate Pass, Purchase Orders are the examples of such output. Statutory outputs: All organization is required to produce a certain amount of reports and forms as required by law.

Operating OutputThese outputs are mainly generated for use of EDP staff and give various indications as to how the system operates. System logs, error messages, status indicators etc. are the examples of such output. These types of output are not concerned for the users.

CHAPTER 4TESTING AND IMPLEMENTATION

4.1 Testing Methodology (Types)

Test cases are developed using various test techniques to achieve more effective testing. By this, software completeness is provided and conditions of testing which get the greatest probability of finding errors are chosen. So, testers do not guess which test cases to chose, and test techniques enable them to design testing conditions in a systematic way. Also, if one combines all sorts of existing test techniques, one will obtain better results rather if one uses just one test technique. Software can be tested in two ways, in another words, one can distinguish two different methods: 1. Black box testing and 2. White box testing.

4.2 Unit TestingUnit testing, also known as component testing , refers to tests that verify the functionality of a specific section of code, usually at the function level. In an object-oriented environment, this is usually at the class level, and the minimal unit tests include the constructors and destructors.These types of tests are usually written by developers as they work on code (white-box style), to ensure that the specific function is working as expected. One function might have multiple tests, to catchcorner casesor other branches in the code. Unit testing alone cannot verify the functionality of a piece of software, but rather is used to assure that the building blocks the software uses work independently of each other.Unit testing is a software development process that involves synchronized application of a broad spectrum of defect prevention and detection strategies in order to reduce software development risks, time, and costs. It is performed by the software developer or engineer during the construction phase of the software development lifecycle. Rather than replace traditional QA focuses, it augments it. Unit testing aims to eliminate construction errors before code is promoted to QA; this strategy is intended to increase the quality of the resulting software as well as the efficiency of the overall development and QA process.Depending on the organization's expectations for software development, unit testing might includestatic code analysis, data flow analysis metrics analysis, peer code reviews, code coverage analysis and other software verification practices.4.3 Integration Testing

Integration testing is any type of software testing that seeks to verify the interfaces between components against a software design. Software components may be integrated in an iterative way or all together ("big bang"). Normally the former is considered a better practice since it allows interface issues to be located more quickly and fixed .Integration testing works to expose defects in the interfaces and interaction between integrated components (modules). Progressively larger groups of tested software components corresponding to elements of the architectural design are integrated and tested until the software works as a system

4.4 System Testing

System testing, or end-to-end testing, tests a completely integrated system to verify that it meets its requirements.For example, a system test might involve testing a logon interface, then creating and editing an entry, plus sending or printing results, followed by summary processing or deletion (or archiving) of entries, then logoff.In addition, the software testing should ensure that the program, as well as working as expected, does not also destroy or partially corrupt its operating environment or cause other processes within that environment to become inoperative (this includes not corrupting shared memory, not consuming or locking up excessive resources and leaving any parallel processes unharmed by its presence).

4.5 Alpha/ Beta Testing

Alpha testingAlpha testing is simulated or actual operational testing by potential users/customers or an independent test team at the developers' site. Alpha testing is often employed for off-the-shelf software as a form of internal acceptance testing, before the software goes to beta testing.Beta testingBeta testing comes after alpha testing and can be considered a form of externaluser acceptance testing. Versions of the software, known asbeta versions, are released to a limited audience outside of the programming team. The software is released to groups of people so that further testing can ensure the product has few faults orbugs. Sometimes, beta versions are made available to the open public to increase thefeedbackfield to a maximal number of future users

4.6 White Box Black Box Testing

White box testing is highly effective in detecting and resolving problems, because bugs (bug or fault is a manifestation of an error in a software) can often be found before they cause trouble. We can shortly define this method as testing software with the knowledge of the internal structure and coding inside the program . White box testing is also called white box analysis, clear box testing or clear box analysis. It is a strategy for software debugging (it is the process of locating and fixing bugs in computer program code or the engineering of a hardware device) in which the tester has excellent knowledge of how the program components interact. This method can be used for Web services applications, and is rarely practical for debugging in large systems and networks ). Besides white box testing is considered as a security testing (the process to determine that an information system protects data and maintains functionality as intended)method that can be used to validate whether code implementation follows intended design, to validate implemented security functionality, and to uncover exploitable vulnerabilities Black box testing is testing software based on output requirements and without any knowledge of the internal structure or coding in the program .In another words, a black box is any device whose workings are not understood by or accessible to its user. For example, in telecommunications, it is a resistor connected to a phone line that makes it impossible for the telephone companys equipment to detect when a call has been answered. In data mining, a black box is an algorithm that doesnt provide an explanation of how it works. In filmmaking, a black box is a dedicated hardware device: equipment that is specifically used for a particular function, but in the financial world, it is a computerized trading system that doesnt make its rules easily available.

5.1Conclusion

With the theoretical inclination of our syllabus it becomes very essential to take the utmost advantage of any opportunity of gaining practical experience that comes along. The construction of this Minor Project PAYROLL MANAGEMENT SYSTEM was one of these opportunities. It gave us the requisite practical knowledge to supplement the already taught theoretical concepts thus making us more competent as a computer engineer.

The project from a personal point of view also helped us in understanding the following aspects of project development: The planning that goes into implementing a project. The importance of proper planning and an organized methodology. The key element of team spirit and co-ordination in a successful project

The project also provided us the opportunity of interacting with our teachers and to gain from their vast experience.

5.2Limitation of System In the present system we cannot search for the report of an employee by entering the name of that employee. Search is based on the employee id. If the payroll company is understaffed and has an abundance of clients, it may become difficult to reach someone when you need it immediately such as when paycheck discrepancies arise. Because the payroll company is located off-site, it is difficult to always know whats going on with your payroll until the actual pay date arrives

5.3Future Scope for Modification Although we tried to be as thorough as possible in the implementation of our project but there were a large number of features we could not implement due to want of time or for other reasons.
