CHAPTER - 1



INTRODUCTION

Employee management and payroll system is the modern computer based record management system of employees of any firm. Since it would be very difficult for any firm to maintain the records of employee on the papers and keep their attendance records also, we tried to convert this manpower to computer power. It is found that this is very efficient way to manage records as well as attendance record through this system.

1.1 Purpose / Objective:

The main goal of this project is to make the record of employee’s easier & quicker.

It is situated for all level of peoples. It provides proper details about the entire employee & their posts. User friendly environment makes the data handling more easily. It easily provides an environment where the user can get information about

all the employees / worker

1.2 Study of existing System:

Exiting EMS is based on the standalone system. It is developed on the access 95 hence it is not compatible on modern

operating system. Existing EMS is not user friendly. It is not provided with the detailed project information done or to be

assigned based on the application. It needs extra manual power also.

Scope of new System:

It is user friendly, can be accessed by any one. It has user id and password system to maintain privacy and security. It is very fast and accurate. No need of extra manual effort. Just need little knowledge to operate the system. Doesn’t require any extra hardware device.

1.3 Software requirements:



Operating System : Windows XP or higher.

Front End tool : Visual Basic 6.0.

Back End tool : Oracle 10g.

Software Justification:

Operating System: As now a day’s windows XP or higher are more common in market, we have designed this software to support all these OS.

Front End tool:Visual Basic 6.0: Microsoft Visual Basic 6.0 is the powerful programming language to develop application for windows. Windows is the operating system, which runs based on messages and with rich user interface.

Back End tool: Oracle 10g: Oracle 10g is very easy to understand and easily programmable. It provides easy database storage also; hence we have used this to store data in form of table of our software.

1.4 Hardware Requirements:



The configuration given below is the Hardware handled for the system development.

Processor : PENTIUM IV or Above

Primary Memory (RAM) : 256 MB or Above

Secondary Memory (Hard disk) : 20 GB or Above

Monitor : COLOR, 15inch or above

Display card : SVGA

Mouse & Keyboard : Any Company

Cabinet : Mini tower ATX

These above hardware requirements are now a days very common and can be found on any computer system. It is kept in mind while designing that no extra hardware support which can be needed to run the software should be there so that it can be afforded by any firm or industry.

CHAPTER - 2

ANALYSIS



2.1 Study of the proposed system:

This system consists of different table which contains the record of employees & it is commented through VB which is the front end. In VB we have seen the information about the employee. You can also provide the different buttons like, add, delete, edit, exit etc. which helps you to edit any data & make your work easier.

2.2 Problem definition:

In the old system the main task of editing is not done easily& it will also take time. But in the proposed system the main assumptions are, the system should already contains all the hardware’s & software’s as well as the person who use this product should familiar with window XP or any operating system.

2.3 Solution strategies:

The main solution of the problem is to provide suitable &user friendly environment to a user so that the user can maintain the detail of employee in a very easy manner.

2.4 Cost Estimation and Scheduling

Project estimation and scheduling were carried out together by the project leader as per the norms of the company. Some cost estimation was done at the early stage before the schedules were drawn up. Once the project was underway, estimates were updated. The factors involved in computing the total cost of a software project were Hardware & software cost, Maintenance cost, Travel and training cost and Effort cost. Scheduling as well as estimating the effort required to develop the software system was done by the project leader in discussion with the Company officials.

TESTING

6.1 SYSTEM TESTING

Software testing is a crucial element of software quality assurance and represents the ultimate review of specification, design and coding. The increasing visibility of software as a system element and the attendant "cost" associated with a software failure are motivating forces for well-planned, thorough testing. Testing is a set of activities that can be planned in advance and conducted systematically. Testing begins at the module level and work towards the integration of entire computers based system. Nothing is complete without testing, as it is vital success of the system.

Unit Testing

Unit testing focuses on the verification of smallest unit of software design of the module. To check whether each module in the software works properly so that it gives desired outputs to the given inputs. All validations and conditions are tested in the module level in unit test. Control paths are tested to ensure the information properly flows into and out of the program unit under test. Boundary condition are tested to ensure that the modules operates at boundary establishes to restrict processing. All independent paths through control structure are exercised to ensure that all statements in a module have been executed at least once. And finally all errors handling paths are tested. In our system, Unit testing has been successfully handled. The test data was given to each module in all respects and have got desired output. Each module has been found working properly.

Black Box Testing

Black Box Testing methods focus on the functional requirements of the software. This testing enables the software engineer to derive sets of input conditions that will fully exercise all functional requirements for a program. This testing attempts to find errors in the following categories: incorrect or missing functions, interface errors, errors in data structure or external database access, performance errors and initialization errors and termination errors. In our system, Black Box testing has been successfully handled. The test input data was given has got desired output.

User Acceptance Testing

The performance of user interactive testing is actually the user show. The user gives live data and checks whether software is giving specified outputs.



6.1.1 SYSTEM IMPLEMENTATION

Implementation is the phase where the system goes for actual functioning. Hence in this phase one has to be cautious because all the efforts undertaken during the project will be fruitful only if the software is properly implemented according to the plans made. The implementation phase is less creative than system design. It is primarily concerned with user training, site preparation and file conversion. Depending on the nature of the system, extensive user training may be required. The initial parameters of the MIS should be modified as the result of programming efforts; programming provides a reality test for the assumptions made by the analyst. The system testing checks the readiness and accuracy of the system to access, update and retrieve data from new files. Once the programs become available, the test data are read into the computer and process.

6.1.2 SYSTEM MAINTENANCE

We may define Software Maintenance by describing four activities that are undertaken after a program is released for use.

Corrective Maintenance

The first maintenance activity occurs since it is unreasonable to assume that software testing will uncover all errors in a large software system. The process of including the diagnosis and correction of one or more errors is called corrective maintenance.

Adaptive Maintenance

This activity that contributes to the definition of maintenance occurs since rapid change is encountered in every aspect of computing. Therefore, adaptive maintenance modifies software to properly interface with the changing environment.

Perfective Maintenance

This activity involves recommendations for new capabilities, modifications to the existing

functions and general enhancements when the software is used. To satisfy these requests, perfective maintenance is performed.

Preventive Maintenance

This activity occurs when software is changed to improve further maintainability or reliability. If the only available element of a Software Configuration is the source code, maintenance activity begins with the evaluation of the code, often complicated by poor internal documentation. The subtle characteristics such as program structure, global data structure, system interfaces and performance & design constraints are difficult to hand lead are often misinterpreted. The amounts of changes that are made to the code are difficult to access.



6.2 Test Cases:

1) Test Case 1:

Case : Testing for login Screen.

Result : On testing username and password system was properly taking input.

2) Test Case 2:

Case : Testing for welcome Screen.

Result : On testing Welcome screen the proper results were obtained. The module was going at proper place on clicking.

3) Test Case 3:

Case : Testing for adding Employee.

Result : The employee was properly added and the fields in the database were properly saved.

4) Test Case 4:

Case : Testing for Modifying Employee.

Result : The employee was properly modified and the fields in the database were properly saved after modification.

5) Test Case 5:

Case : Testing for Deleting Employee.

Result : The employee was properly deleted and the fields in the database were properly deleted.

6) Test Case 6:

Case : Testing for Employee Salary Sheet.

Result : On entering the emp number, month and year the system was properly giving the salary sheet of the entered employee number and also giving proper deductions.

7) Test Case 7:

Case : Testing for Data Report.

Result : The data report was properly shown with the list of all the employees department wise with their basic, gross, net salary description.



CHAPTER – 7

LIMITATIONS AND FURTHER ENHANCEMENTS

Limitations:

Skyworld Tech Employee Management System is limited to our control. Any change or modification can be done by us only.

It is not an online application or system. We have not provided any backup system for this. The system need to run oracle on background.

Further Enhancements:

Search details can be enhanced by detailed identification of searching problems and rectification steps by company.

This system is entirely designed for STAND ALONE usage, according to the need of the customer if needed the same system can be designed with Network facility to handle the branch activities also.

To make this system Online and creating data backups. Integrated Password management facility can be created.





CHAPTER - 8

CONCLUSION

The Employee Management System didn’t automate 100% of their work, but it is really a good start to computerize everything and entire Detail can be 100% computerized.

As far as the work done so far much care was given about the user friendliness and a very good interaction with the end users. The interface are so designed and channeled the users can never make any mistake while using the application, for an example while adding new record, user can’t go out without either saving or canceling the operation, till the time either they save or cancel the current operation all other operations are blocked. There is no chance of making any mistake in the application.
