摘要
ADO．NET是微软针对AD0的缺陷而重新设计的一种全新的数据库访问模型，它支持工业标准，集合了所有用于数据处理的类型。论述了ADO．NET的结构和其中的主要对象，ADO．NET的显著特点就是结合了XML技术、实现了在断开的概念下、基于多层架构实现数据库的访问，是专门针对Web设计的。以访问国网南京自动化研究院水情所的水库水文WDS数据库为例，探讨了利用ADO．NET技术访问数据库的方式，为利用．NET（ASP．NET）开发电网水调自动化系统提供数据基础。
ADO.NET is a new method model of visiting database aiming at ADO＇s deficiency, it supports industry-standard, and gathers all categories of data processing. The paper expounds ADO.NET＇s framework and it＇s dominant object, its outstanding feature is to combine XML technique, and to realize visiting the database on disconnection, which based on muhilayer architecture, special directed towards Web design. It takes visiting WDS database, for a example, explores method of visiting database with ADO.NET, and offers data-basis for Hydropower Dispatching Automation System for Power Grid.
