微软公司的ADO（ActiveX Data Objects）是一个用于访问数据源的COM组件。它提供了编程语言和统一数据访问方式OLE DB的一个中间层。允许开发人员编写访问数据的代码而不用关心数据库是如何实现的，而只用关心到数据库的连接。访问数据库的时候，关于SQL的知识不是必要的，但是特定数据库支持的SQL命令仍可以通过ADO中的命令对象来执行。

ActiveX Data Objects ADO
（重定向自ActiveX Data Object）
In computing, Microsoft's ActiveX Data Objects (ADO) comprises a set of Component Object Model (COM) objects for accessing data sources. A part of MDAC (Microsoft Data Access Components), it provides a middleware layer between programming languages and OLE DB (a means of accessing data stores, whether databases or not, in a uniform manner). ADO allows a developer to write programs that access data without knowing how the database is implemented; developers must be aware of the database for connection only. No knowledge of SQL is required to access a database when using ADO, although one can use ADO to execute SQL commands directly (with the disadvantage of introducing a dependency upon the type of database used).
