PREFACEThe “Multiple Choice Questions” is a great improvement over the

manual system like hand written exams. The computerization of

the system has speed up the process and it is time consuming. It

is very difficult to keep answer papers and all such things. The

system was thoroughly checked and tested with dummy data. The

system avoids data redundancy and inconsistency. It provides

security and integrity. Data is easily retrieved. Thus the system is

user friendly.

Being able to process data and use effectively is vital to both

private and public organizations. Without the improvement and reliability

of system, it would be impossible for a business to exist for very long.

The information system of organization consist of a number of

subsystem involved in the collection where complex decision problem

are solved by computer routines.

PROJECT DESCRIPTION

The project “Multiple Choice Questions ” is developed in Java, which

mainly focuses on basic Exam operations. “ Multiple Choice Questions ”

is a windows application written for 32bit Windows operating systems,

designed to help users to give exams.

In our project Multiple Choice Questions we can create an account,

writing exam using that account and we get our result also.In this new user

can “SignUp” and already exists user can “LogIn” and then “SelectExam”

and perform their test.It is easy to understand . this project can be easily

accessed by both technical and non-technical users and can fulfill their

needs.

The “Multiple Choice Questions” is a great

improvement over the manual system like hand written exams.

The computerization of the system has speed up the process and

it is time consuming. It is very difficult to keep answer papers

and all such things. The system was thoroughly checked and

tested with dummy data. The system avoids data redundancy and

inconsistency. It provides security and integrity. Data is easily

retrieved. Thus the system is user friendly.

Our proposed system has the following advantages.

User friendly Interface

Fast access to database

Less error

Storage Capacity

INTRODUCTION

Java is a general purpose ,object oriented programming language developed by Sun Microsystems of USA in 1991.Originally called Oak by James Gosling .Java was designed for the development of software for consumer electronic devices like TVs , VCRs,and such other electronic machines.

Features of Java-

1. Compiled And Interpreted2. Platform Independent And Portable3. Object Oriented4. Robust And Secure5. Distributed6. Simple , Small And Familiar7. Multithreaded And Interactive8. High Performance

INTRODUCTION TO THE AWTAWT stands for Abstract Window ToolKit. The Abstract Window Toolkit provides many classes for programmers to use. It is your connection between your application and the native GUI. The AWT hides you from the underlying details of the GUI your application will be running on and thus is at very high level of abstraction.

It is a Java package and can be used in any Java program by importing java.awt.* via the import keyword.

Structure of the AWT

The structure of the AWT is rather simple. Controls are components that allow a user to interact with your application in various ways:-.

The AWT hierarchyClasses:

Component o Button o Checkbox o Choice o Container Panel Window o Label o List o Scrollbar o Text Compoment TextArea TextField

7

Image MenuComponent o MenuBar o MenuItem CheckboxMenuItem Menu

INTRODUCTION TO SWING

Swing is a set of classes that provide more powerful and flexible component than are possible with the AWT. these components such as buttons ,check boxes and labels, Swing supplies several exciting additions , including scroll panes ,trees and tables.these components such as buttons hae more capabilities in Swing . for example, a button may have both image and a text string associated with it. Also the image can be changed as the state of button changes. Unlike, AWT component , Swing components are not implemented by platform independent.

The Swing component classes are:-

Classes Description

AbstractButton Abstract superclass for Swing button

JApplet The swing version of Applet.

JButton The swing push button classes.

JCheckBox The swing checkbox classes.

8

JComboBox Encapsulate a Combo Box(combination of a drop

down list & text field)

JLabel The swing version of a Label.

JRadioButton The swing version of a RadioButton.

JScrollPane Encapsulate a Scroll Window.

JTextField The swing version of a TextField.

INTRODUCTION OF JDBC

JDBC (Java Database Connectivity) is a standard API for accessing relational databases from a Java program.  This interface makes it easy to access a database because it provides an abstract layer that hides the low-level details, such as managing sockets.  It also provides for interoperability and portability since it allows a single application to access multiple database management systems simultaneously.  For example, a single application can query and manipulate a database in Oracle and a database in DB2.  Communication with a database management system (DBMS) is through method calls.  These calls are passed to the driver, which in turn, translates them into DBMS-specific calls.  The driver basically acts like a set of library routines.  Therefore, to get your program to communicate with a particular DBMS, you need a compatible JDBC driver.  The basic steps to get your program up and running are:

 9

1. Load the driver and register it with the driver manager2. Connect to a database3. Create a statement4. Execute a query and retrieve the results, or make changes to the database5. Disconnect from the database.

The need of JDBC

Java has been called "the vehicle by which developers will be able to bring dynamic application behavior to the Web" . Users can download applets from either local or remote Web servers for execution inside popular Web browsers such as Netscape Navigat or. Applets run disconnected from the server, just like native applications. Java however, has fallen short of its widely ability to connect to outside resources via a build-in API. The first release of the Java Developers Kit (JDK) in early 1995 had no integrated support for accessing databases. The functionality of Java made it easy to build tools for accessing databases, but there was no prescription about how such drivers ought to function. Several vendors produced good tools for database access but here were no general guidelines for how database access tools should be written.

JDBC Architecture

The JDBC Architecture consists of two layers: the JDBC API, which provides the application-to-JDBC Manager connection, and the JDBC Driver API, which supports the JDBC Manager-to-Driver Connection.

10

Two models for database access are supported by the JDBC API. They are the two-tier model and the three-tier model.

The two-tier model

In the two-tier model, a Java applet or application talks directly to the database. This requires a JDBC driver that can communicate with the particular database management system (DBMS) being accessed. SQL statements are delivered to the database, and the results are sent back to the user.

11

This is referred to as a client/server configuration, in which the users machine is the client and the machine housing the database is the server. The database may be located on another machine to which the user is connected via a network.

The three-tier model

In the three-tier model, commands are sent to a middle tier of services, which then send SQL statements to the database. The database processes the SQL statements and sends the results back to the middle tier, which then sends them to the user.

12

DATABASE DESIGN The general theme behind a database is to handle information as an

integrated whole. A database is a collection of interrelated data stored with

minimum redundancy to serve many users quickly and effectively. After

designing the input and output, the analyst must concentrate on database

design or how data should be organized around user requirements. The

general objective is to make information access, easy quick, inexpensive

and flexible for other users. During database design the following

objectives are concerned:-

Controlled Redundancy

Easy to learn and use

More information and low cost

Accuracy

Integrity

ABOUT MS-ACCESS

Before you compile the project you have to set the ODBC connection then only it will work properly

Let us see How to set ODBC connection (MS Access)

1. Click Start button +Click Settings

2. Click Control Panel21

2. Select Administrative tools + Click data Sources (ODBC)

22

4. Then you get ‘ODBC Data Source Administrator’ window (shown below) +Click Add Button

5. Create New Data Source (shown below) +select Microsoft Access Driver (*.mdb,*.accdb) + press Finish button

23

6. ODBC Microsoft Access Set up (shown below) + gives Data Source Name +select Database (Press select button) +select your database (shown below) + Press Ok button

7. Before you close the window make sure that your DSN name is correct or not (shown below) +Press Ok button

24

Now you got the DSN name (ExamSuite)This is the way for connecting ODBC, if

you have any doubt please mail us.
