Introduction
This document provides a detailed design of the system. Please refer to the requirement

2.
Programming platform
The system will be written in Java language. Thus our software is systemindependent and can be run in both MS Windows and Unix system. During
development process we will use the MS Windows system.
3.
Database
The database being used is the DB2 database system, and the connection to the
database is made by Java’s JDBC interface. The tables will be created using SQL
statements; the runtime SQL will be sent to database and the query result will be
sent back to application by JDBC connection.
