摘要
根据校园数据集成系统的具体需求,设计了一个异构数据库系统,以能够充分地利用学校现有的数据库资源。介绍了局部数据库变化数据的几种提取方法并对其进行了改进,探讨了XML文档与数据库的转换方法以及数据库异构性的解决办法,对数据在传输过程中的安全性问题进行了研究。
According to specific the demand ofcampus data integration system, a heterogeneous database integration system is designed, which can fully utilize the existing information resources. Firstly, several extracting methods of the Changed data of local database are introduced and improved. After that, the conversion method between XML document and database and solutions of database heterogeneity are explored. Finally, the safety problem in the course of data transmission is studied.
