摘要
基于网格的异构数据库整合是将各种异构数据库资源封装成网格服务,网格用户无需了解各异构数据库的细节,通过网格服务访问、操作数据库.服务基于XML规范和本体论整合与交换信息,利用本体与数据库的映射生成标准操作语言访问数据库.
The heterogeneous database integration based on grids is to pack various kinds of heterogeneous database sources into a grid service.The users visit and manipulate the databases without need to understand the details of various heterogeneous databases.The grid service integrates and exchanges information based on XML standard and ontology.The databases are accessed by standard operation languages which are generated by the mapping between databases and ontology.
