说明：  数据库开发的文件说明，ADO(ActiveX Data Object)是Microsoft数据库应用程序开发的新接口，是建立在OLE DB之上的高层数据库访问技术，请不必为此担心，即使你对OLE DB，COM不了解也能轻松对付ADO,因为它非常简单易用，甚至比你以往所接触的ODBC API、DAO、RDO都要容易使用，并不失灵活性。
(database development documented, ADO (ActiveX Data Object) is a Microsoft database applications open the new interface is built on top of the OLE DB database access technology senior, Please do not worry, even if you right OLE DB, COM ignorance can easily deal with ADO, because it is very easy to use, even more than the past, you have contact with the ODBC API, DAO, RDO easier to use, and not lose flexibility.)
