文中介绍.Net开发环境下，通过自定义数据库访问控件和对象关系映射技术（Object Relational Mapping，简称ORM）实现的一种全新的数据持久层中间件。该中间件实现数据库表对象到用户UI控件的自动映射，在降低对开发人员数据库开发技术掌握水平要求的同时，大大提高开发效率，使开发人员可以致力于后台逻辑与用户UI设计，为用户带来更好的体验。本中间件通过我公司在新疆维吾尔自治区开发的多个管理信息系统（MIS）的应用与实践，已经验证了其快捷性、稳定性和可伸缩性，能够有效的提高软件开发效率。%This article describes how to achieve a brand new middleware of data persistence layer under the .Net environment through custom database access controls and object relational mapping technology. The middleware can map database tables with UI controls automatically, reducing database development requirement of the developers, and greatly Improve development efficiency, allows developers and users committed to the buiness logic and UI designment for better user experience. Through our several management information systems in Xinjiang Uygur Autonomous Region, The middleware has verified its quickness, stability and scalability. It can make software development more effectively.
