摘要
随着信息技术的发展和企业间协作的加强,企业的各种异构数据资源之间的协同也成为一个研究的热点。在将这些异构数据源进行协同的同时,不可避免地会出现数据的流动或迁移问题。提出在协同数据库的基础上实现数据迁移的一种模型,分析迁移模型的功能组成与实现,给出关于异构数据迁移的几个建议。建立该模型的意义在于减少协同数据库系统中数据库的数量和降低维护的成本。
With the developmentofinformationtechnology and deeply collaboration of the enterprises, thecooperationof heterogeneous datasources is studied with keen interest. At the same time, data flow or data migration will inevitably come up. A data migration model is brought forward based on cooperative database, which mainly focuses on the function components and implementation of the migration model. At last, some advices about heterogeneous datasources are given. The significance of this model is to decrease the number of databases in cooperative database system and reduce the cost of maintenance.
