In view of above, the designed system uses three-tier
C/S architecture, i.e. client, application server and database
management system (DBMS), see to Figure 1. Client is used as user interface, application server as application
logic, and DBMS as creating, using and maintaining
database. Application server can realize centralized
management on distributed data and its operating system is
Windows NT or above systems, its database management
system is SQL Server 2008. Taking into account of many
system users on client and different characteristics of
operating system, Windows XP or above versions is used
in the operation system [2-4].
