This type of testing usually done for 2 tier applications (usually developed for LAN)
Here we will be having front-end and backend.
The application launched on front-end will be having forms and reports which will be monitoring and manipulating data
E.g: applications developed in VB, VC++, Core Java, C, C++, D2K, PowerBuilder etc.,
The backend for these applications would be MS Access, SQL Server, Oracle, Sybase, Mysql, Quadbase
