2 Profile of problem assigned

In an Educational Institution, circulating information among its students is of foremost

importance. A lot of processes need to be managed for proper management of information in an

institution. From processing of admission forms to displaying information on the notice board all

the processes are managed manually. To display information centrally is a difficult task in an

educational institution. So, the profile of the problem is to manage and circulate information in

an educational institution easily and effectively.

3 Study of existing system3.1 Manual System- In this type of system paper and pen is used to keep the track of all the

activities and events.

Most of the organizations use paper to keep records, show notices etc.

This manual system has various drawbacks like:

It is very difficult to maintain all the records manually i.e. by using paper and pen.

Searching records in manual system is a very time consuming process.

Sometimes it is not possible to keep the track of all the documents centrally. E.g. Usually

organizations do not keep the track of all the notices displayed on their notice board.

Large manpower is required to manage data in a manual system.

Data in manual system is less secure as there is no username and password concept to

make the data secure.

3.2 Automated existing system

There are some existing automated systems which has been used to manage data in educational

institutions. But these existing systems have some flaws which are:

9

The existing systems which are available are basically bound to a particular institution in

which they are used.

Existing systems are not able to manage the data of more than one organization at a time,

without making any change into it.

4 System Requirements

4.1 Problem statementTo reduce the risk, money, time used in manual system the System KHABAR HIMACHAL has

been think of and been formulated.

4.2 Functions to be provided

KHABAR HIMACHAL has been formulated by keeping in mind, the major needs of all the

educational institutions. It has been formulated to provide facilities according to the designation

of the person.

The person can have one of the following designations in khabar himachal:

.

4.2.1 Admin: An organization can have one and only one admin. An admin has control over

the data related to his/her own organization. Admin can make operators, assign privilege to

operators.

4.2.2: An organization can have multiple Reporters. Reporters can be given certain privileges

by the admin.

In Short we can say KhabarHimachal provides various functionalities like:

Admin can manage records of all the reporters of his/her organization.

Any information available in the form of images and videos can be displayed centrally by

an admin.

5.2 Software Environment

5.2.1 J2SE – Java 2 Standard Edition

There are two principal products in the Java SE platform family:

5.2.1.1) Java SE Runtime Environment (JRE)

The Java Runtime Environment (JRE) provides the libraries, the Java Virtual Machine, and other

components to run applets and applications written in the Java programming language. In

addition, two key deployment technologies are part of the JRE: Java Plug-in, which enables

applets to run in popular browsers; and Java Web Start, which deploys standalone applications

over a network. It is also the foundation for the technologies in the Java 2 Platform, Enterprise

Edition (J2EE) for enterprise software development and deployment. The JRE does not contain

tools and utilities such as compilers or debuggers for developing applets and applications.

5.2.1.2 Java Development Kit (JDK).

The Java Development Kit (JDK) is a superset of the JRE, and contains everything that is in the

JRE, plus tools such as the compilers and debuggers necessary for developing applets and

applications.

11

5.2.1.3 Java SE API

The Java SE application programming interface (API) defines the manner by which an applet or

application can make requests to and use the functionality available in the compiled Java SE

class libraries. (The Java SE class libraries are also part of the Java SE platform.)

The Java SE API consists of core technologies, Desktop (or client) technologies, and other

technologies.

Core components provide essential functionality for writing powerful enterprise-worthy

programs in key areas such as database access, security, remote method invocation

(RMI), and communications.

Desktop components add a full range of features to help build applications that provide a

rich user experience – deployment products such as Java Plug-in, component modeling

APIs such as JavaBeans, and a graphical user interface.

Other components round out the functionality.

5.2.1.4 Java Virtual Machine

The Java Virtual Machine is responsible for the hardware- and operating system-independence of

the Java SE platform, the small size of compiled code (bytecodes), and platform security.

5.2.1.5 Java Platform Tools

The Java SE platform works with an array of tools, including Integrated Development

Environments (IDEs), performance and testing tools, and performance monitoring tools.

5.2.2 J2EE – Java 2 Enterprise Edition

Java Platform, Enterprise Edition (Java EE) builds on the solid foundation of Java Platform,

Standard Edition (Java SE) and is the industry standard for implementing enterprise-class

service-oriented architecture (SOA) and next-generation web applications. The SDKs contain

Sun GlassFish Enterprise Server, previously named Sun Java System Application Server, and

provide support for Java EE 5/ Java EE 5 specifications.

Java Platform, Enterprise Edition (Java EE) is a set of coordinated technologies that significantly

reduces the cost and complexity of developing, deploying, and managing multitier, server-centric

applications. Building on the Java Platform, Standard Edition (Java SE), Java EE adds the

capabilities that provide a complete, stable, secure, and fast Java platform for the enterprise.

Java Platform, Enterprise Edition 5 (Java EE 5) focuses on making development easier, yet

retains the richness of the J2EE 1.4 platform. Offering new and updated features such as

Enterprise JavaBeans (EJB) Technology 3.0, JavaServer Faces (JSF) Technology, and the latest

web services APIs, Java EE 5 makes coding simpler and more straightforward, but maintains the

power that has established Java EE as the premier platform for web services and enterprise

application development.

The Java EE 5 SDK and Java Application Platform SDK provide support for Java EE 5

specifications, and the Java Application Platform SDK features additional runtimes such as Open

ESB, Portlet Container, and Sun Java System Access Manager.

With a primary focus on ease of development, the Java EE 5 platform offers developers ready

access to a secure, portable, and scalable platform for their enterprise applications. Java EE 5

technology makes coding simpler and more straightforward through the use of Java annotations,

programming based on POJOs (Plain Old Java Objects), and resource injection concepts. Sun

GlassFish Enterprise Server (formerly Sun Java System Application Server and hereafter

referred to as Application Server) v2.1 supports all the technologies required by the Java EE 5

specification. A brief summary of the key Java EE 5 technologies is provided here.

13

Apache Software License. Apache Tomcat is intended to be a collaboration of the best-of-breed

developers from around the world.

Apache Tomcat is an implementation of the Java Servlet and JavaServer Pages technologies.

Apache Tomcat version 6.0 implements the Servlet 2.5 and JavaServer Pages 2.1

A standard installation of Tomcat 7.0 makes all of the following APIs available

for use by web applications (by placing them in "lib"):

* annotations-api.jar (Annotations package)

* catalina.jar (Tomcat Catalina implementation)

* catalina-ant.jar (Tomcat Catalina Ant tasks)

* catalina-ha.jar (High availability package)

* catalina-tribes.jar (Group communication)

* ecj-3.7.2.jar (Eclipse JDT Java compiler)

* el-api.jar (EL 2.2 API)

One can make additional APIs available to all of your web applications by putting unpacked

classes into a "classes" directory (not created by default), or by placing them in JAR files in the

"lib" directory.

18

5.2.2.4 MySQL Database ServerMySQL, the most popular Open Source SQL database server, is developed, distributed, and

supported by MySQL AB, now purchased by Sun MicroSystem.

The official way to pronounce “MySQL” is “My EssQue Ell” (not “my sequel”).

Following are main features of MySQL:

MySQL is a database management system.

A database is a structured collection of data. It may be anything from a simple shopping

list to a picture gallery or the vast amounts of information in a corporate network. To add,

access, and process data stored in a computer database, you need a database management

system such as MySQL Server.

MySQL is a relational database management system.

A relational database stores data in separate tables rather than putting all the data in one

big storeroom. This adds speed and flexibility. The SQL part of “MySQL” stands for

“Structured Query Language.” SQL is the most common standardized language used to

access databases and is defined by the ANSI/ISO SQL Standard. The SQL standard has

been evolving since 1986 and several versions exist. In this manual, “SQL-92” refers to

the standard released in 1992, “SQL:1999” refers to the standard released in 1999, and

“SQL:2003” refers to the current version of the standard. We use the phrase “the SQL

standard” to mean the current version of the SQL Standard at any time.

MySQL software is Open Source.

Open Source means that it is possible for anyone to use and modify the software.

Anybody can download the MySQL software from the Internet and use it without paying

anything.

The MySQL Database Server is very fast, reliable, and easy to use.

19

MySQL Server was originally developed to handle large databases much faster than

existing solutions and has been successfully used in highly demanding production

environments for several years.

MySQL Server works in client/server or embedded systems.

The MySQL Database Software is a client/server system that consists of a multi-threaded

SQL server that supports different backends, several different client programs and

libraries, administrative tools, and a wide range of application programming interfaces

(APIs).

A large amount of contributed MySQL software is available. It is very likely that your

favorite application or language supports the MySQL Database Server.

Following features are implemented in MySQL 5.0:

VARCHAR Data Type: True VARCHAR support. Maximum effective length of

VARCHAR is 65,532 bytes now, and no stripping of trailing whitespace occurs.

BIT Data Type

Precision Math

Strict Mode and Standard Error Handling

Data Dictionary (Information Schema)

Stored Procedures

Triggers

Views

Cursors

Instance Manager: Can be used to start and stop the MySQL Server, even from a remote

host.

Storage Engines: New storage engines include ARCHIVE and FEDERATED.

20

6 Solution Strategies The Strategy was to divide the application into three layers to make it an enterprise application.

The development process was done by keeping in mind the concept of following threelayers:

6.1 Presentation layerWeb Interface

6.1.1 HTML (Hypertext Markup Language) HTML stands for Hyper Text Markup Language

HTML is not a programming language, it is a markup language

A markup language is a set of markup tags

HTML uses markup tags to describe web pages

The purpose of a web browser (like Internet Explorer or Firefox) is to read HTML documents

and display them as web pages. The browser does not display the HTML tags, but uses the tags

to interpret the content of the page.

6.1.2 CSS(Cascading Style Sheet) CSS stands for Cascading Style Sheets

Styles define how to display HTML elements

Styles are normally stored in Style Sheets

Styles were added to HTML 4.0 to solve a problem

External Style Sheets can save you a lot of work

External Style Sheets are stored in CSS files

Multiple style definitions will cascade into one

6.1.3 JavaScript

21

JavaScript is used in millions of Web pages to improve the design, validate forms, detect

browsers, create cookies, and much more. JavaScript is the most popular scripting language on

the internet, and works in all major browsers, such as Internet Explorer, Firefox, and Opera.

JavaScript was designed to add interactivity to HTML pages

JavaScript is a scripting language

A scripting language is a lightweight programming language

JavaScript is usually embedded directly into HTML pages

JavaScript is an interpreted language (means that scripts execute without preliminary compilation)

Everyone can use JavaScript without purchasing a license

Purpose of using JavaScript

JavaScript gives HTML designers a programming

JavaScript can put dynamic text into an HTML page

JavaScript can react to events

JavaScript can read and write HTML elements

JavaScript can be used to validate data

6.2 Business Logic layerBusiness Layer

22

Core Java Technologies

Java

Java is Platform Independent, Secure, Object Oriented, Scalable, and Robust

Programming Language.

It consists of two parts

JVM stands for Java Virtual Machine, which is run time environment to execute

the java programs.

Java API (Application Programming Interface) that consists of inbuilt classes

used in java programs.

Exception Handling

An exception is an event, which occurs during the execution of a program that

disrupts the normal flow of the program's instructions.

When an error occurs within a method, the method creates an object and hands it

off to the runtime system. The object, called an exception object, contains

information about the error, including its type and the state of the program

when the error occurred. Creating an exception object and handing it to the

runtime system is called throwing an exception.

Multithreading

Threads are called lightweight processes. Threads exist within a process — every process has at

least one. Threads share the process's resources, including memory and open files. This makes

for efficient, but potentially problematic, communication.

When number of threads is executing simultaneously in same memory but different path of

execution .this process is known as multithreading.

23

Collections Framework

A collection is simply an object that groups multiple elements into a single unit. Collections are

used to store, retrieve, manipulate, and communicate aggregate data.

A collections framework is a unified architecture for representing and manipulating collections.

JDBC

JDBC (Java Database Connectivity) is an API, which is used for the communication of java

programs with different databases.

Java Mail API

The Java Mail API provides a platform-independent and protocol-independent framework to

build mail and messaging applications.

Servlets

Servlets are basically a part of Java Platform, Enterprise Edition (Java EE) and is a technology

that is used for extending the functionality of the servers that host application access via request-

response programming model.

JSP

JSP (Java Server Pages) a technology of Java Platform, Enterprise Edition (Java EE) is used for

server-side programming and with the help of JSP we can segregate the work of a web designer

and a developer.

24

J2EE – Java 2 Enterprise Edition

Java Platform, Enterprise Edition (Java EE) builds on the solid foundation of Java Platform,

Standard Edition (Java SE) and is the industry standard for implementing enterprise-class

service-oriented architecture (SOA) and next-generation web applications. The SDKs contain

Sun GlassFish Enterprise Server, previously named Sun Java System Application Server, and

provide support for Java EE 5/ Java EE 5 specifications.A brief summary of the key Java EE 5

technologies is provided here.

Netbeans

A free, open-source Integrated Development Environment for software developers.

One can get all the tools you need to create professional desktop, enterprise, web, and mobile

applications with the Java language, C/C++, and even dynamic languages such as PHP,

JavaScript, Groovy, and Ruby.

Glassfish

GlassFish is an enterprise-quality Java EE 5 application server that offers advanced clustering,

centralized administration, and best-in-class performance built by the GlassFish community. The

Java EE SDKs contain Sun GlassFish Enterprise Server, previously named Sun Java System

Application Server.

range of industries and organizations.

25

Apache Tomcat is developed in an open and participatory environment and released under the

Apache Software License. Apache Tomcat is intended to be a collaboration of the best-of-breed

developers from around the world.

MySQL Database ServerMySQL, the most popular Open Source SQL database server, is developed, distributed, and

supported by MySQL AB, now purchased by Sun MicroSystem.

The official way to pronounce “MySQL” is “My EssQue Ell” (not “my sequel”). MySQL Server

is used to create database.It is a RDBMS(Relational database management system). It stores data

in the form of tables. It uses different constraints to keep the data consistent and non-

redundant. The different constraints used are: Primary key constraint- It ensures that data in field

should be unique and not null. Foreign key constraint- It is used to make relationship between

two tables. It ensures that the field with the foreign key constraint can contain only those values

that are in the Primary table’s field with primary key.

System Implementation

Implementation IssuesImplementation phase of the software development is concerned with translating the design

specifications into the source code. After the system has been designed, and arrives the stage of

putting it into actual usage known as the implementation of the system. This involves putting up

of actual practical usage of the theoretically designed system. The primary goal of

implementation is to write the source code and the internal documentation so that conformance

of the code to its specifications can easily be verified and so the debugging, modifications and

testing are eased. This goal can be achieved by making the source code as clear and as

straightforward as possible. Simplicity, Elegance and Clarity are the hallmarks of good programs

whereas complexity are indications of inadequate design and misdirected thinking. The system

implementation is a fairly complex and expensive task requiring numerous inter-dependent

activities. It involves the effort of a number of groups of people: user and the programmers and

the computer operating staff etc. This needs a proper planning to carry out the task successfully.

Thus it involves the following activities:

◦ Writing and testing of programs individually

◦ Testing the system as a whole using the live data

◦ Training and Education of the users and supervisory staff

Source code clarity is enhance buy using structured coding techniques, by efficient coding style,

by appropriate supporting documents, by efficient internal comments and by features provided in

the modern programming language.

The following are the structured coding techniques:

Single Entry, Single Exit

Data Encapsulation

Using recursion for appropriate problems

31

1.1 User Verification - The customized and tested application will be validated using

production database in a small department or region of the organization. A sample pool

of system owners, system designers and system users are used to ensure all levels have

been completed. Like “Mental Arithmetic Aid” is installed on various systems with the

organization, where we want to develop it, so that it can be verified or tested by various

people.

1.2 User Acceptance - Based on the acceptance of the verification stage the application is

made fully operational throughout the organization.

1.3 User Training – Using the same sample pool from User Verification or a new client

defined team, representatives of system owners, system designers, system support and system

users are trained in various modules. Using a combination of classroom and hands-on training of

the concepts and operation of the selected modules.

32

Design Phase

After the analysis phase we have with us the details of the existing system and the requirements

of the user for the new system. This phase diverts focus from the problem domain to the solution

domain. It acts as a bridge between the requirement phase and its solution. The design phase

focuses on the detailed implementation of the system recommended in the feasibility study.

Emphasis is on translating performance specifications into design specifications.

Systems design is the process or art of defining the architecture, components, modules,

interfaces, and data for a system to satisfy specified requirements. One could see it as the

application of systems theory to product development. There is some overlap with the disciplines

of systems analysis, systems architecture and systems engineering.

Object-oriented analysis and design (OOAD) methods are becoming the most widely used

methods for computer system design. The UML has become the standard language used in

Object-oriented analysis and design. It is widely used for modeling software systems and is

increasingly used for high designing non-software systems and organizations.

The External DesignExternal design consists of conceiving, planning out and specifying the externally observable

characteristics of the software product. These characteristics include user displays or user

interface forms and the report formats, external data sources and the functional characteristics,

performance requirements etc. External design begins during the analysis phase and continues

into the design phase.

33

Logical design

The logical design of a system pertains to an abstract representation of the data flows, inputs and

outputs of the system. This is often conducted via modelling, which involves a simplistic (and

sometimes graphical) representation of an actual system. In the context of systems design,

modelling can undertake the following forms, including:

Data flow diagrams

Entity Life Histories

Entity Relationship Diagrams

Physical designThe physical design relates to the actual input and output processes of the system. This is laid

down in terms of how data is input into a system, how it is verified/authenticated, how it is

processed, and how it is displayed as output.

Physical design, in this context, does not refer to the tangible physical design of an information

system. To use an analogy, a personal computer's physical design involves input via a keyboard,

processing within the CPU, and output via a monitor, printer, etc. It would not concern the actual

layout of the tangible hardware, which for a PC would be a monitor, CPU, motherboard, hard

drive, modems, video/graphics cards, USB slots, etc.

Design Methodology: Rapid Application Development (RAD)Rapid Application Development (RAD) is a methodology in which a systems designer produces

prototypes for an end-user. The end-user reviews the prototype, and offers feedback on its

suitability. This process is repeated until the end-user is satisfied with the final system.
