摘要:: 在全程办税系统中,不同的税务部门采用了不同的操作系统和数据库系统,因此访问异构分布式数据库成为关键技术之一。针对该系统不同数据库类型现状,分析了异构分布式数据库访问方法的优劣,提出了采用基于ADO.NET的数据访问中间件实现异构分布式数据库访问的思想、全程办税系统数据访问中间件的体系结构和中间件模型,详细讨论了基于ADO.NET的数据访问中间件的具体实现技术,并对中间件进行了测试。测试结果验证了该中间件访问异构分布式数据库的可行性和有效性。该中间件具有较强的独立性、移植性与复用性,具有较好的推广价值

Abstract:: The different tax＇s departments adopted different operating systems and database system in whole process tax system.Thus access of heterogeneous distributed database becomes one of the key technologies.Aiming at heterogneity of database in whole process tax system,this advantages and disadvantages of access heterogeneous distributed database is analyzed.This article introduces the design idea for using ADO.NET-based database middleware to access heterogeneous distributed database.And system structure and model of middleware to access database is introduced.The way to realize database middleware based on the ADO.NET is discussed,middle-ware is tested.Test results show the feasibility and validity of the middleware of heterogeneous distributed database access.The middleware has strong independence and portability and reusability.It has a good promotion value
