Net。 看看Wiki上的MDAC定义:“Microsoft Data Access Components（MDAC）是微软专门为数据访问功能而发展的应用程序开发接口，做为微软的统一化数据访问（Universal Data Access; UDA）解决方案的核心组成，最初的版本在1996年时发表，其组成组件有ODBC，OLE DB以及ADO，其中ADO是在Visual Basic上唯一的数据访问管道，而OLE DB则是基于COM之上，供C/C 访问与提供数据的接口，ODBC则是统一化的数据访问API。”也就是说，ODBC, OLE DB, ADO都是这个解决方案的组件。 再看看这张调用图，很多事情就不言自明了。(其实我觉得这图有些不准确，.
Net Managed Provider应该有条专线直通Data Stores, 这样才能体现出Sql Server的性能优越性嘛...) 2. 总结一下就是：以前访问oracle，就要用oracle 的api, 要访问db2，就要用db2的api，这样写出来的代码都是不一样的，一旦领导层要更换数据库，结果程序员就倒血霉了，这不是好方法，ODBC因此应运而生。 3. ODBC 算是较早期的数据访问库，现在已经过时, 但还偶有用处, 看下面图片: 下面是其wiki描述： "In computing, ODBC (Open Database Connectivity) is a standard C programming language interface for accessing database management systems (DBMS).
It was developed by the SQL Access Group in 1992 to standardize the use of a DBMS by an application.
ODBC provides a universal middleware layer between the application and DBMS, allowing the application developer to use a single interface.
