摘要：
针对开放网格服务架构-数据访问与接口中间件只面向JDBC的局限性，提出构建一个基于.net架构的异构数据统一访问接口中间件。采用XML Web Service技术跨平台性和ADO.net增强的数据库访问能力，既实现了接口实现的通用性与易扩展性，又实现了接口对数据访问、数据库连接、数据格式转换、数据传输、数据库集成等底层细节的屏蔽。测试结果表明，该接口中间件具有通用性、灵活性和可靠性。

Abstract:
Aiming at the limitation of Open Grid Services Architecture-Data Access and Interface(OGSA-DAI) middleware only face to JDBC, an unified heterogeneous data access interface middleware based on .net framework is proposed. XML Web Service cross-platform technology and enhanced ADO.net database access capability are used, which not only get a common interface and easy scalability, but also shield the bottom of the details on interface for data access, database connectivity, data format conversion, data transmission, database integration etc. Test result shows that the middleware is current, flexible and reliable.
