PROJECT OVERVIEW

This project performs all tasks related to

paper setting, starting from preparing question paper to

printing paper. This project is mainly designed to be used by our

college administration for generating a Question paper. The question

paper can be used for the semester examinations. It selects questions

randomly from a question bank available in the database. The

database contains the subjects and their respective questions of all

semesters, for the various branches of Engineering. The faculty can

also edit the question papers, if they have any desired question to be

included in the question paper. There are very rare chances for the

disclosure of Question paper as it provides good security, due to the

unpredictable questions generated.

The Platform used in this project is Net Beans-IDE and Java

Database connectivity (JDBC) is used as the interface. The JDBC &

ODBC drivers are configured to interact with the NET BEANS-IDE, to

facilitate flawless integration of backend and front end of the

project. JDBC is used for accessing databases in the Java

applications. The databases are entered by creating tables using the

MYSQL commands on Oracle server embedded in the Net Beans-IDE.

About Netbeans:

NetBeans refers to both a platform framework for Java desktop

applications and an integrated development environment (IDE) for

developing with Java, JavaScript, PHP, Python (no longer supported after NetBeans ,

Groovy, C, C++, Scala , Clojure and others

The NetBeans IDE is written in Java and can run on Windows, OS X,

Linux, Solaris and other platforms supporting a compatible JVM. A pre-

existing JVM or a JDK is not required.

The NetBeans platform allows applications to be developed from a set of

modular software components called modules. Applications based on the

NetBeans platform (including the NetBeans IDE) can be extended by

third party developers.

NetBeans Platform

The NetBeans Platform is a reusable framework for simplifying the

development of Java Swing desktop applications. The NetBeans IDE

bundle for Java SE contains what is needed to start developing NetBeans

plugins and NetBeans Platform based applications; no additional SDK is

required.

Applications can install modules dynamically. Any application can

include the Update Center module to allow users of the application to

download digitally signed upgrades and new features directly into the

running application. Reinstalling an upgrade or a new release does not

force users to download the entire application again.

The platform offers reusable services common to desktop applications,

allowing developers to focus on the logic specific to their application.

Among the features of the platform are:

• User interface management (e.g. menus and toolbars)

• User settings management

• Storage management (saving and loading any kind of data)

• Window management

• Wizard framework (supports step-by-step dialogs)

• NetBeans Visual Library

• Integrated development tools

• NetBeans IDE is a free, open-source, cross-platform IDE with

built-in-support for Java Programming Language.

NetBeans IDE is an open-source integrated development environment.

NetBeans IDE supports development of all Java application types (Java

SE (including JavaFX), Java ME, web, EJB and mobile applications) out

of the box. Among other features are an Ant-based project system,

Maven support, refactorings, version control (supporting CVS,

Subversion, Mercurial and Clearcase).

Modularity: All the functions of the IDE are provided by modules. Each

module provides a well defined function, such as support for the Java

language, editing, or support for the CVS versioning system, and SVN.

NetBeans contains all the modules needed for Java development in a

single download, allowing the user to start working immediately.

Using JDBC in General

1. Load the JDBC driver. To load a driver, you specify the classname

of the database driver in the Class.forName method. By doing so,

you automatically create a driver instance and register it with the

JDBC driver manager.

2. Define the connection URL. In JDBC, a connection URL specifies

the server host, port, and database name with which to establish a

connection.

3. Establish the connection. With the connection URL, username,

and password, a network connection to the database can be established.

Once the connection is established, database queries can be

performed until the connection is closed.

4. Create a Statement object. Creating a Statement object enables

you to send queries and commands to the database.

5. Execute a query or update. Given a Statement object, you can

send SQL statements to the database by using the execute,

executeQuery, executeUpdate, or executeBatch methods.

6. Process the results. When a database query is executed, a

ResultSet is returned. The ResultSet represents a set of rows

and columns that you can process by calls to next and various

getXxx methods.

7. Close the connection. When you are finished performing queries

and processing results, you should close the connection, releasing

resources to the database.

Once you have a Statement object, you can use it to send SQL queries

by using the

executeQuery method, which returns an object of type ResultSet. Here is

an

example.

String query = "SELECT col1, col2, col3 FROM sometable";

ResultSet resultSet = statement.executeQuery(query);

The following list summarizes commonly used methods in the Statement

class.

• executeQuery. Executes an SQL query and returns the data in a

ResultSet. The ResultSet may be empty, but never null.

• executeUpdate. Used for UPDATE, INSERT, or DELETE commands.

Returns the number of rows affected, which could be zero. Also

provides support for Data Definition Language (DDL) commands, for

example, CREATE TABLE, DROP TABLE, and ALTER TABLE.
