浅析高职院校校园网建设中的数据库异构现象

Database Isomerism in the Building of Higher Vocational Campus Network

高职院校校园网建设的早期,由于缺乏整体规划,没有统一的信息标准,使得各个管理信息系统处于相对独立的状态,成为"信息孤岛",导致了数据异构现象。分析了校园网数据库异构现象的成因、异构数据库共享实现的迫切要求,尝试利用SQL Server的数据库异构技术,解决数据库系统内外异构数据的共享问题。此方法也可省略重构数据库的繁琐工作,节约成本,提高效率。

The lack of overall planning and a unified information standard at the early stage of higher vocational campus network building makes the information-managing systems independent from one another, becoming ＂information islands＂ with the isomerism of data. This paper analy- zes the causes of isomerism in campus network database, clarifying the urgent request of realizing heterogeneous database sharing. It proceeds to use SQL Server database heterogeneous technolo- gy to realize heterogeneous data sharing. This method can effectively avoid the reconstruction of database, reduce cost and improve efficiency.
