一种新的数据库访问技术——OLE DB接口技术

A New Data Bases Access Technigue——OLE DB Interface Technique

由于数据结构的差异 ,关系型数据库和非关系型数据库很难在同一平台上实现统一的编程接口。为此 ,本文通过介绍基于COM的OLEDB接口技术 ,以及与ODBC等其它数据库接口技术的对比 ,阐明了OLEDB的技术优势 ,并在VC平台上实现了异构数据源访问接口。

It is very difficult to make the unitive programming interface between the relational databases and the irrelational databases in a same platform because of the difference of the data structure. The paper states the advantages of OLE DB and uses ADO realizing the interface of visiting the isomerous databases on the VC platform through introducing the new COM based interface technigue OLE DB and comparing with other database interfaces, for example ODBC etc.
