跨数据库平台应用系统移植中间件的研究与开发

Research and Development of Middleware about Application Software′s Transporting in Heterogeneous Databases

软件业对跨数据库平台应用系统移植的需求日益增多,跨数据库平台应用移植的中间件成为一个重点研究方向。本文通过研究异构数据库之间的差异,以及异构数据库间相同的语义对象的转化,语义集成,完成对数据库操作语言对象化的转换。使应用软件对异构数据库的操作透明,实现应用软件在这异构数据库上的移植。

Because of the more requirements for application systems between different databases, the research is more important in this field. This article completes this research after lucubrates in the differences of heterogeneous databases. By researching semantic integration and transforming , the article achieves the transforming Data Manipulation Language into an object. Because database is transparent to the application software, it＇s more smooth to transport data in different databases and satisfies more requirements for applications in heterogeneous databases.
