Design and implementation of database application module

A design outline on the implementation of database application module by using "PowerBuilder" data-window was presented, and some part of the implementation process was given. Rapid database application can be built when using this module on the basis of single table or master-detail table. This module can also provide primary operations to database tables such as "insert","delete","modify","query", and "sort" operation. The utilization of this module proved that it is simple to design, easy to implement and maintain, and stable, which is practical.
