4. SYSTEM ANALYSIS:

Analysis means the study of existing system, in other words we can say that how the survey is

presently being conducted by any organization. It is a problem solving activity that requires

intensive communication between the system users and system developers. System analysis orstudy is an important phase of any system development process. The system is studied to the

minutest detail and analyzed. The system analyst plays the role of the interrogator and dwells

deep into the working of the present system. The system is viewed as a whole and the input to

the system are identified. The outputs from the organizations are traced to the various

processes. System analysis is concerned with becoming aware of the problem, identifying the

relevant and decisional variables, analyzing and synthesizing the various factors and determining

an optimal or at least a satisfactory solution or program of action.

A detailed study of the process must be made by various techniques like interviews,

questionnaires etc. The data collected by these sources must be scrutinized to arrive to a

conclusion. The conclusion is an understanding of how the system functions. This system is

called the existing system. Now the existing system is subjected to close study and problem areas

are identified. The designer now functions as a problem solver and tries to sort out the

difficulties that the enterprise faces. The solutions are given as proposals. The proposal is then

weighed with the existing system analytically and the best one is selected. The proposal is

presented to the user for an endorsement by the user. The proposal is reviewed on user request

and suitable changes are made. This is loop that ends as soon as the user is satisfied with

proposal.

Preliminary study is the process of gathering and interpreting facts, using the information for

further studies on the system. Preliminary study is problem solving activity that requires

intensive communication between the system users and system developers. It does various

feasibility studies. In these studies a rough figure of the system activities can be obtained, from

which the decision about the strategies to be followed for effective system study and analysis can

be taken.

Here a detailed study of existing system is carried along with all the steps in system analysis. An

idea for creating a better project was carried and the next steps were followed.



5. FEASIBILITY STUDY AND PROPOSED OBJECTIVES

Feasibility study is made to see if the project on completion will serve the purpose of the

organization for the amount of work, effort and the time that spend on it. Feasibility study lets

the developer foresee the future of the project and the usefulness. A feasibility study of a system proposal is according to its workability, which is the impact on the organization, ability to meet

their 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 for development.

5.1 TYPES OF FEASIBILITY STUDY :

1. Economic Feasibility

2. Technical Feasibility

3. Operational Financial Feasibility

5.1.1 ECONOMIC FEASIBILITY:

Economic analysis ascertains the cost and benefits from the proposed system.The development

cost, hardware and software cost etc. are determined. The expected benefits of the system are

also ascertains.

The following are some of the important financial questions asked during preliminary

investigation:

• The costs conduct a full system investigation.

• The cost of the hardware and software.

• The benefits in the form of reduced costs or fewer costly errors.

Since the system is developed as part of project work, there is no manual cost to spend for the

proposed system. Also all the resources are already available, it give an indication of the system

is economically possible for development.



5.1.2 TECHNICAL FEASIBILITY:

The system must be evaluated from the technical point of view first. The assessment of this

feasibility must be based on an outline design of the system requirement in the terms of input,

output, programs and procedures. Having identified an outline system, the investigation must go

on to suggest the type of equipment, required method developing the system, of running the

system once it has been designed.

Technical issues raised during the investigation are:

• Does the existing technology sufficient for the suggested one?

• Can the system expand if developed?

The project should be developed such that the necessary functions and performance are achieved

within the constraints. The project is developed within latest technology. Through the technology

may become obsolete after some period of time, due to the fact that never version of same

software supports older versions, the system may still be used. So there are minimal constraints

involved with this project. The system has been developed using Java the project is technically

feasible for development.

5.1.3 BEHAVIORAL FEASIBILITY:

This includes the following questions:

• Is there sufficient support for the users?

• Will the proposed system cause harm?



The project would be beneficial because it satisfies the objectives when developed and installed.

All behavioral aspects are considered carefully and conclude that the project is behaviorally

feasible.

6. DESIGN AND DATA FLOW DIAGRAM SYSTEM DESIGN

Design is the first step into the development phase for any engineered product or system. Design

is a creative process. A good design is the key to effective system. The term ―design‖ is defined

as ―the process of applying various techniques and principles for the purpose of defining a process or a system in sufficient detail to permit its physical realization‖. It may be defined as a

process of applying various techniques and principles for the purpose of defining a device, a

process or a system in sufficient detail to permit its physical realization. Software design sits at

the technical kernel of the software engineering process and is applied regardless of the

development paradigm that is used. The system design develops the architectural detail required

to build a system or product. As in the case of any systematic approach, this software too has

undergone the best possible design phase fine tuning all efficiency, performance and accuracy

levels. The design phase is a transition from a user oriented document to a document to the

programmers or database personnel. System design goes through two phases of development:

Logical and Physical Design.

6.1 LOGICAL DESIGN:

The logical flow of a system and define the boundaries of a system. It includes the following

steps:

• Reviews the current physical system – its data flows, file content, volumes , Frequencies

etc.

• Prepares output specifications – that is, determines the format, content and Frequency of

reports.



• Prepares input specifications – format, content and most of the input functions.

• Prepares edit, security and control specifications.

• Specifies the implementation plan.

• Prepares a logical design walk through of the information flow, output, input, Controls

and implementation plan.

• Reviews benefits, costs, target dates and system constraints.

6.2 PHYSICAL DESIGN:

Physical system produces the working systems by define the design specifications that tell the

programmers exactly what the candidate system must do. It includes the following steps.

• Design the physical system.

• Specify input and output media.

• Design the database and specify backup procedures.

• Design physical information flow through the system and a physical design

• Plan system implementation.

• Prepare a conversion schedule and target date.

• Determine training procedures, courses and timetable.

• Devise a test and implementation plan and specify any new hardware/software.

• Update benefits , costs , conversion date and system constraints

Design/Specification activities:

• Concept formulation.

• Problem understanding.

• High level requirements proposals.

• Feasibility study.



• Requirements engineering.

• Architectural design

7. Software Environments

JAVA

Introduction: Java is an object-oriented programming language with a built-in application

programming interface (API) that can handle graphics and user interfaces and that can be used to

create applications or applets. Because of its rich set of API's, similar to Macintosh andWindows, and its platform independence, Java can also be thought of as a platform in itself. Java

also has standard libraries for doing mathematics.

Much of the syntax of Java is the same as C and C++. One major difference is that Java does not

have pointers. However, the biggest difference is that you must write object oriented code in

Java. Procedural pieces of code can only be embedded in objects. In the following we assume

that the reader has some familiarity with a programming language. In particular, some familiarity

with the syntax of C/C++ is useful.In Java we distinguish between applications, which are programs that perform the same functions

as those written in other programming languages, and applets, which are programs that can be

embedded in a Web page and accessed over the Internet. Our initial focus will be on writing



applications. When a program is compiled, a byte code is produced that can be read and executed

by any platform that can run Java.

Characteristics Of JAVA:

1) Platform Independent:

Java is a platform for application development. A platform is a loosely defined computer

industry buzzword that typically means some combination of hardware and system software that

will mostly run all the same software.

Java byte code is exactly the same on every platform.. Java programs that have been compiled

into byte code still need an interpreter to execute them on any given platform. The interpreterreads the byte code and translates it into the native language of the host machine on the fly. Since

the byte code is completely platform independent, only the interpreter and a few native libraries

need to be ported to get Java to run on a new computer or operating system.

2) Object oriented

In object-oriented programs data is represented by objects. Objects have two sections, fields

(instance variables) and methods. Fields tell you what an object is. Methods tell you what an

object does. These fields and methods are closely tied to the object's real world characteristics

and behavior. When a program is run messages are passed back and forth between objects. When

an object receives a message it responds accordingly as defined by its methods.

3) Robust

Java implements a robust exception handling mechanism to deal with both expected and

unexpected errors. The worst that an applet can do to a host system is bringing down the runtime

environment. It cannot bring down the entire system.

Most importantly Java applets can be executed in an environment that prohibits them from

introducing viruses, deleting or modifying files, or otherwise destroying data and crashing the

host computer. A Java enabled web browser checks the byte codes of an applet to verify that it

doesn't do anything nasty before it will run the applet.



4) Multithreaded

Java is inherently multi-threaded. A single Java program can have many different threads

executing independently and continuously. Three Java applets on the same page can run together

with each getting equal time from the CPU with very little extra effort on the part of the programmer.

5) High performance

Java byte codes can be compiled on the fly to code that rivals C++ in speed using a "just-in-time

compiler." Several companies are also working on native-machine-architecture compilers for

Java. These will produce executable code that does not require a separate interpreter, and that is

indistinguishable in speed from C++.

6) Dynamic

Java programs carry with them substantial amounts of run-time type information that is used to

verify and resolve accesses to objects at run-time. This makes it possible to dynamically link

code in a safe and expedient manner. The java programming language is unusual than other

programming languages it first compiles and then interprets the program. Compile first translate

the program into intermediate language called intermediate language called java byte code. Java

byte code is platform independent code, which is further interpreted by the interpreter on the java

platform. Interpreter parses and run each java byte code instruction on the computer.

Compilation occurs only once, interpretation occurs each time when the program is executed.

Java byte code helps in making the program ―write once, run anywhere‖. The program can be

compiled into byte code by any platform that is having the java compiler; the compiled java byte

code program is ready to run on any machine having the java virtual machine (JVM). JVM is an

interpreter for byte code .



Advantages of Java:

1) Simple

Java has the bare bones functionality needed to implement its rich feature set. It does not add lots

of syntactic sugar or unnecessary features.

2) Object-Oriented

Almost everything in Java is a class, a method or an object. Only the most basic primitive

operations and data types (int, for, while, etc.) are at a sub-object level.

3) Platform Independent

Java programs are compiled to a byte code format that can be read and run by interpreters on

many platforms including Windows 95, Windows NT, and Solaris 2.3 and later.

4) Safe

Java code can be executed in an environment that prohibits it from introducing viruses, deleting

or modifying files, or otherwise performing data destroying and computer crashing operations.

5) High Performance

Java can be compiled on the fly with a Just-In-Time compiler (JIT) to code that rivals C++ in

speed.

6) Multi-Threaded

Java is inherently multi-threaded. A single Java program can have many different things

processing independently and continuously.

Java platform:



A java platform is the hardware or software environment in which a program runs. The java

platform has two components: Java Virtual Machine (JVM)

1. Java Application Programming Interface (Java API)

2. JVM is a standardized hypothetical computer, which is emulated inside your computer by a program.

Java Source Code

Java Compiler

Java Source Code

Java Virtual Machine

The program by the interpreter

Java interpreter

Computer Operating System

The Java API is a large collection of ready-made software components that provide many useful

capabilities, such as graphical user interface (GUI). The java API is grouped into libraries of

related classes and interfaces these libraries are known as packages.



AWT:

The Java programming language class library provides a user interface toolkit called the Abstract

Windowing Toolkit, or the AWT. The AWT is both powerful and flexible. Newcomers,

however, often find that its power is veiled. The class and method descriptions found in thedistributed documentation provide little guidance for the new programmer. Furthermore, the

available examples often leave many important questions unanswered. Of course, newcomers

should expect some difficulty. Effective graphical user interfaces are inherently challenging to

design and implement, and the sometimes complicated interactions between classes in the AWT

only make this task more complex. However, with proper guidance, the creation of a graphical

user interface using the AWT is not only possible, but relatively straightforward.

This article covers some of the philosophy behind the AWT and addresses the practical concern

of how to create a simple user interface for an applet or application.

User interface

The user interface is that part of a program that interacts with the user of the program. User

interfaces take many forms. These forms range in complexity from simple command-lineinterfaces to the point-and-click graphical user interfaces provided by many modern applications.

At the lowest level, the operating system transmits information from the mouse and keyboard to

the program as input, and provides pixels for program output. The AWT was designed so that

programmers don't have worry about the details of tracking the mouse or reading the keyboard,

nor attend to the details of writing to the screen. The AWT provides a well-designed object-

oriented interface to these low-level services and resources.

Because the Java programming language is platform-independent, the AWT must also be

platform-independent. The AWT was designed to provide a common set of tools for graphical

user interface design that work on a variety of platforms.



The user interface elements provided by the AWT are implemented using each platform's native

GUI toolkit, thereby preserving the look and feel of each platform. This is one of the AWT's

strongest points. The disadvantage of such an approach is the fact that a graphical user interfacedesigned on one platform may look different when displayed on another platform.

Components and containers

A graphical user interface is built of graphical elements called components. Typical components

include such items as buttons, scrollbars, and text fields. Components allow the user to interact

with the program and provide the user with visual feedback about the state of the program. In the

AWT, all user interface components are instances of class Component or one of its subtypes.

Components do not stand alone, but rather are found within containers. Containers contain and

control the layout of components. Containers are themselves components, and can thus be placed

inside other containers. In the AWT, all containers are instances of class Container or one of its

subtypes.

Java AWT Components:

Java's Abstract Windowing Toolkit provides many of the user interface objects we find in the

Windows environment. These are called "Components" of the Java AWT. The applet below

contains most of the components we will use to create a graphical user interface (GUI) for our

applets. It simply initializes and creates the components but does not handle any of the events

they trigger. Click on the hyperlink to the right of the component in order to see an example of

the code that includes the event handlers.

Label Component



The Label component is the simplest of Java's AWT. Labels consist of a text string for display

only and they never call an action method. The syntax is as follows:

Label labelname = new Label("This label is for decoration only.");

The justification of a label can be left, right, or centered. The line below will create a label that isright justified.

Label labelname = new Label("This label is for decoration only.",Label.RIGHT);

We can change the text of a label or get the label's text using the labelname.setText("This is

new text."); or String labelText = labelname.getText(); methods. We can change the alignment or

get the alignment of a label with the labelname.setAlignment(Label.CENTER); or int label

Alignment = labelname.getAlignment(); methods.

import java.applet.*;

import java.awt.*;

public class label extends Applet

{

public void init()

{

Label firstLabel = new Label("Labels exist simply ");

add(firstLabel);



Label secLabel = new Label("to place text on the screen");

add(secLabel);

Label thirdLabel = new Label("They can be aligned left, right

or center.");

add(thirdLabel);

}

}

After compiling HYPERLINK "http://www.krhs.net/computerscience/java/gloss.htm" this

program we need to create an HTML page with a reference to the class file. It will require a

graphic window that is large enough to contain the labels (200 x 100 is a good size for this label).

Button Component

The Button component of Java's AWT is a workhorse of any GUI. The only decision you need to

make when you create one is whether or not you want it to have a label. The syntax is as follows

Button buttonname = new Button(button label);

Where 'buttonname' is the name you want to give the object and 'button label' is the text you

want to appear on the button. Once you create the button you add it to the applet (or other

container) by entering the command

add(buttonname);

We can change the button's label or get the label's text using the Button.setLabel or

Button.getLabel methods. Now that we can create the buttons and manipulate their labels we can

investigate the code that makes the button perform the operations we need.

The Applet below changes the background color by simply clicking on one of the labeled

buttons.

http://www.krhs.net/computerscience/java/gloss.htm









import java.applet.*;

import java.awt.*;

public class button extends Applet

{

public void init()

{

add(new Button("Red"));

add(new Button("White"));

add(new Button("Blue"));

add(new Label("Hit a Button to

change the screen color");

}

public boolean action(Event evt, Object

whatAction)

{

if (!(evt.target instanceof

Button))

{

return false;

}

String buttonLabel = (String)

whatAction;



if (buttonLabel=="Red")

setBackground(Color.red);

if (buttonLabel=="White")

setBackground(Color.white);

if (buttonLabel=="Blue")

setBackground(Color.blue);

repaint();

return true;

}

}

Check Boxes

Check boxes are used as on-off or yes-no switches since every time you click on one, you toggle

to the opposite selection. You are able to select as many or as few check boxes as you like. Then

when you write your program, the state of each check box can be compared to determine an

action. A button is needed to trigger an event to check the state of the check boxes.

The following line will create a checkbox with 'Apples' as a label, null as a place holder for a

group argument, and false to indicate it is not selected. (The group argument is used for radio

buttons which are a special kind of check boxes.)

Checkbox apples = new Checkbox("Apples", null, false);

Once you create the checkbox just add it to the applet (or other container) by entering the

command

add(apples);



where apples is the Checkbox name. We can change the Checkbox label or get the Checkbox

text using the Checkbox.setLabel(String) or Checkbox.getLabel( ) methods. The getState(

)method returns true of false, depending on whether the Checkbox is selected or unselected. The

setState(boolean) method changes the Checkbox's state to true (for selected) or false(for

unselected.)

Consider the example below which illustrates how Checkboxes can be implemented.

The Applet below prints a list of fruits. Check as many or few as you like. The "Done" button

triggers an event in order to check which boxes were selected. A list of selected items is then

painted on the applet window.

Radio Buttons

Radio buttons or checkbox groups are special kinds of checkboxes. They look the same as

checkboxes but within a particular group of them, only one can be selected at a time.

The following line will create a series of radio buttons named 'colors'.

CheckboxGroup colors = new CheckboxGroup();

Once you create the series of radio buttons, add the individual checkboxes. There are three

arguments: the radio button label, the group, and true or false, depending on whether the button

is selected or unselected. Only one radio button in the group can be selected.

add(new Checkbox("Red",colors,false));

add(new Checkbox("White",colors,false));

add(new Checkbox("Green",colors,false));

add(new Checkbox("Blue",colors,false));

The same checkbox methods that were presented on the checkbox page can be implemented with

radio buttons in the group. These include:

Checkbox.setLabel(String)Checkbox.getLabel( )

getState( )

setState(boolean)



The methods getCheckboxGroup() and setCheckboxGroup() can be used to access and change

the group of a given checkbox. To get or set the currently selected checkbox, use the

getCurrent() or setCurrent(Checkbox) methods.

List Boxes

The List class allows the creation of a scrolling list of values that may be selected alone or

together. If you want to create a list that does not allow multiple selections, use the following

command line. Thelist is an instance of the list.

List thelist = new List();

If you want to create a list that does allow multiple selections, use the following command line

which creates a list with 8 visible entries and multiple selections turned on. .

List thelist = new List(8, true);

Once you have created the list, the addItem method enables you to add new entries.

thelist.addItem("Coffee");

thelist.addItem("Bananas");

thelist.addItem("Oranges");

If you want to add an item at a specific location in the list, for example the first position, use the

following line. Adding an item to position -1 or at a higher position than the number on the list,

adds it to the end of the list.

thelist.addItem("Coffee", 0);

Choice Boxes

The Choice class is a lot like lists but allows you to conserve space since it provides a pop-up

menu of text string choices. The menu title displays the current choice. To work with a choice

box, an instance of the Choice class must be created.

Choice theoptions = new Choice();

Once you have created the choice, the addItem method enables you to add new entries.



theoptions.addItem("Red");

theoptions.addItem("Green");

The currently selected item can be changed by name or index.

theoption.select("Red");OR

theoption.select(0);

The getSelectedIndex and getSelectedItem methods would return the position of the selected

item and string name of the selected item respectively.

The Choice class calls the action method whenever a choice is made, regardless of whether it is a

new choice or not. The parameter whatAction contains the name of the selected item. The

following example shows how a choice box can be used to change the background color of an

applet window.

Text Area

The TextField and TextArea classes are two different Java classes for entering text data. The

TextField class handles only one line of text. The TextArea class handles multiple lines. The

example on this page illustrates text fields and a text echo. The following line will create a

TextField with 20 columns.

TextField plaintext = new TextField(20);

The text field can also be initialized with some text when it is created.

TextField plaintext = new TextField("First Name Last Name");

Scrollbars

The Scrollbar class provides a user interface to scroll through a range of integer values. These

values can then be associated with a range of colors, the months of a year or a variety of otheruses. The Scrollbar's maximum and minimum values can be initialized as well as its minor

changes (line increments) and major changes (page increments).

The following line will create a horizontal scrollbar.

Scrollbar colorscroll = new Scrollbar(Scrollbar.HORIZONTAL);



The following line will create a vertical scrollbar with a starting position of 0, a page size of 5, a

minimum value of 0, and a maximum value of 255.

Scrollbar colorscroll = new Scrollbar(Scrollbar.VERTICAL, 0, 5, 0, 255);

There are three different parts of a scrollbar that allow you to select a value between themaximum and minimum in different ways. The arrows increment or decrement with the line

update which can be set to a small unit. Its value is 1 by default. Clicking between the arrow and

scroll box increments or decrements by a page value which is 10 by default. The box in the

middle allows you to click and drag to traverse the scroll bar quickly from end to end.

Swing

Swing is the primary Java GUI widget toolkit . It is part of Oracle 's Java Foundation Classes

(JFC) — an API for providing a graphical user interface (GUI) for Java programs.

Swing was developed to provide a more sophisticated set of GUI components than the earlier

Abstract Window Toolkit (AWT) . Swing provides a native look and feel that emulates the look

and feel of several platforms, and also supports a pluggable look and feel that allows applications

to have a look and feel unrelated to the underlying platform.

It has more powerful and flexible components than AWT. In addition to familiar componentssuch as buttons, check boxes and labels, Swing provides several advanced components such as

tabbed panel, scroll panes, trees, tables and lists.

Unlike AWT components, Swing components are not implemented by platform-specific code.

Instead they are written entirely in Java and therefore are platform-independent. The term

"lightweight" is used to describe such an element

9. TESTING AND IMPLEMENTATION

9.1 TESTING

The most important activity at the implementation stage is the system testing with the objective

of validating the system against the designed criteria. During the development cycle, user was

involved in all the phases that are analysis, design and coding. After each phase the user was

asked whether he was satisfied with the output and the desired rectification was done at the

moment. During coding, generally bottom up technique is used. Firstly the lower level modules

are coded and then they are integrated together. Thus before implementation, it involves the



testing of the system. The testing phase involves testing first of separate parts of the system and

then finally of the system as a whole. Each independent module is tested first and then the

complete system is tested. This is the most important phase of the system development. The user

carries out this testing and test data is also prepared by the user to check for all possible

combinations of correct data as well as the wrong data that is trapped by the system. So the

testing phase consists of the following steps:

Unit testing:

In the bottom of coding technique, each module is tested individually. Firstly the module is

tested with some test data that covers all the possible paths and then the actual data was fed to

check for results.

Integration testing:

After all the modules are ready and duly tested, these have to be integrated into the application.

This integrated application was again tested first with the test data and then with the actual data.

Validation testing or System testing:

This is the final step in testing. In this the entire system was tested as a whole with all forms,

code, modules and class modules. This form of testing is popularly known as Black Box testing

or System tests. Black Box testing method focuses on the functional requirements of the

software. That is, Black Box testing enables the software engineer to derive sets of input

conditions that will fully exercise all functional requirements for a program.

The testing will be performed considering the following points:

1. Software testing which involves testing of all the programs together. This involves the testing

of system software utilities being used and specifically develops application software.



2. Flow of data within the organization

3. Accuracy of report output

4. Incomplete data formats

5. Halts due to various reasons and the restart procedures.

6. Range of items and incorrect formats

7. Invalid combination of data records.

8. Access control mechanism used to prevent unauthorized access to the system.

9.2 IMPLEMENTATION

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

specifications into the source code. After the system has been designed, 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 andtesting 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:1) Single Entry, Single Exit

2) Data Encapsulation

3) Using recursion for appropriate problems
