数据库结构复用技术研究

Database structure reuse techniques

现代企业是不断发展的。伴随着这种发展,企业的需求也在不断变化。如何让企业信息系统适应这种变化就显得非常重要,这特别需要数据库结构具有良好的可重用性和可扩展性。通过对关系数据库管理系统的研究,结合软件技术发展趋势,提出了一种数据库结构可重用和可扩展的数据库实现方式,讨论了用这种方式实现数据库的过程,并给出了实现数据库的一个简单例子。

It is very important how the corporation information system （IS） can adapt the change on the modem enerprised, which especially demands that the database structure of the IS has good reusability and extensibility.built on the research of RDBMS and the trend of sottware techniques, a pattern to manufacture database was brought forward that the database structure could be reused and extended. The processes of implementing database was discussed using this pattern, and a simplified example for it was given.
