The Software Reuse And Application Research

How to rapidly and expeditiously develop a face-to-internet, open, safe and reliable integrated information management system, and to mostly decrease the development cost is a burning question in front of software developers.This article introduces the software-reuse technology, and high light onthe research of the core technology——component reuse. Under the conditionof information management system, puts forward a suitable component model, and with the method in domain engineering, designs a reusable domain component database, then analyzes the problems of database reuse, dynamic data widows' construction , consequently applies the software reuse to the certain information management systems.
