ABSTRACT

                The Automatic Database Schema Generation is a system, which allows the developers to focus on creating the database using the GUI interface .The user needs to fulfill the requirements in the interface and he can perform the database operations which he wants and can create the database.                     
          
 This project aims at creation of an automatic database schema generation. This project will be accessible to all developers and its facility allows developers to focus on creating the database schema on the basis of JSP while letting the application server define table based on the fields in JSP and relationships between them. This system provides the following facilities.              

This facilitates the user to focus much on application   aspects leaving behind the database aspects.
This project allows users to generate database schema generation without having much knowledge of database Aspects.

MODULES:

Number of Modules:5

1) SQL Query Pane Module
This module is used to retrieve data from the database by using SQL Queries. The User interface is designed with a query pane to type the query, where a user can type the sql query. The sql query is taken by the module as input and generates the output of that query. The output is displayed in a tabular manner.





2) Import Option Module
This module is developed to retrieve schema from the external files. The supported files are .sql files. .sql files contains the set of queries that can be executed. This module uses the FTP protocol which will enable the web server to load the files.

3) Export Option Module
          The user can export sql Structure, sql Data or both based on some conditions into 3 types of files.
  • .sql files
  • .html files
  • .csv files(Excel Files)
4) Operations Module                             
The user can create table with constraints, Alter the table, Rename the Table, Drop table.
The user can Alter the existing table like by using following keys.

o   Alter column

    • Rename column
    • Drop column
    • Empty column
 The user can rename the table by giving the old name and new name. The user can drop the table by selecting the table name from the select box.

 5) Search Database Module
The user must search based on keywords
o   Search looks for column names only
o   Search looks for data only




EXISTING SYSTEM:


There are many Database Management systems available today. The Database designer is familiar with any one of the database Management Systems. Let us consider a condition when a database designer required to design the schema for an application on different DBMS. He required to learn all the DBMS User Interfaces. Where some of them are GUI (Graphic User Interface) based and others are CUI(Character User Interface).

Drawbacks of Existing System:

Through this approach to alter or to edit a large database schema, It consumes more time for a Database Designer. The operations like altering the table structure, Editing the table,  Dropping columns, searching for a column name, searching for a data in the table.. etc.,
To Design and alter the Database schema there exists different user interfaces for different DBMS.

PROPOSED SYSTEM:
The Automatic Database Schema Generation System provides the following features.
1.      The Automatic Database Schema Generation System provides a Common User Interface to interact with all the databases.
2.      Here the user interface is Graphical User Interface.
3.      This application is a Web based Application.
4.      Being a web based application it doesn’t require any client side installation.
5.      Any number of users can interact with the system simultaneously.
6.      Centralized database connectivity.
7.      Using Session management the interaction more flexible and secure.
