摘要
在很多的实际应用中需要集成地访问异构的数据源,我们在DM异构数据源集成系统中采用了一种自描述的数据模型OEM,并在此基础上构造查询语言(MSL)和针对不同数据源的捆绑器。从而很好地实现了异构数据源的集成。
Many applications require integrated access to heterogeneous information stored at sources with different data models and access mechanisms. We describe in this paper a semistructured data model which we called OEM and a query language MSL adopted in the DM heterogeneous data integration system.
