Our primary experience has been in replacing the legacy-UI layer with a contemporary Rich-UI layer built on Web 2.0 technologies and continuing to leverage on the server-side business logic assets of the application. 

Need for the system

Need for the system• The development of system is required to ease the naive user to search a

database by using a natural language such as English.

• To search a database a user has to learn the SQL which is sometimes difficult for the end user .

• To reduce the efforts of the end user to query a database.

Scope of work

Scope of work

The scope of the proposed system is as follows:

1) To work with any RDBMS one should know the syntax of the commands of that particular database software (Microsoft SQL, Oracle, etc.).

2) Here the Natural language processing is done on English i.e. the input statements have to be in English.

3) Input from the user is taken in the form of Questions like wh- form like what, who, where.

Operating Environment

Operating Environment

Software Requirements:

1. JDK 1.5 or above

2. IDE for the development of Java Code

3. Operating system : Windows XP or above

4. Database – SQL SERVER 2000 or ACCESS

Operating Environment

Hardware Requirements:

1. 1 GB Hard Disk space

2. 512 MB RAM

3. 1GHz or above processor

4. VGA Display Adapter – with higher resolution

Technology Used

Technology Used

J2SE (Java 2 Standard Edition) is used for the development of the project.

Serialized Objects / Serialization - Database in Java

Project database needs are handled in java.

1. First step is to use data structures like Vectors and Lists. These come under Java Collections API

Technology Used

• E.g. a class Student to hold all the student information. Now theseclasses need to be pre-compiled and called within Java application aslibraries. This is called as a Java Class Library

C. Now class objects cannot be saved to hard drive directly. We needto convert these objects to bytes so that they can be saved to harddrive. To do this we must use a concept called as Serialization.Basically it is a concept where in objects are converted to bytestreams so that they can be saved to hard drive or sent via internetand vice versa. The reverse process is called as deSerialization.

D. Finally to save these bytes to hard drive or to send them vianetwork we need Java I/O.

Introduction To System

Introduction To SystemKeword Management:• This phase contains declaring the notations used by the end user for a

particular SQL term.

Example 1 :

SQL term: select can have the following notations used by the user:

1)Show

2)Give

3)Display

4)provide and many more.

Introduction To System

Example 2:

SQL Term: ‘ < ‘ (less than) can have the following notations :

1)less

2)lessthan

3)less than

4)lesser

5)lower and many more

The application becomes more and more efficient as we manage the more and more keywords and assign the user notations to them.

Introduction To System

Alias Management:• This phase contains declaring the alias names used by the user

for the tables in the database.

Example 1:

Database Table Name: Employee user can use following notations for this:

1)emp

2)emps

3)employis(spelling mistake)

Introduction To System

Example 2:

Database Table Name: Customer user can use the following notations for this:

1)cust

2)customar

3)custmer

The application becomes more and more efficient as we manage the more and more alias for the user notations.

Introduction To System

• For the system to be more efficient the administrator of the system has to manage the large number of keywords and the alias used for the tables by the user.

• As the system is used more and more the administrator can add more and more keywords and alias so the system becomes more robust and can generate result for the more general queries of the user.
