ADO技术在电网故障仿真培训系统中的应用

传统的基于数据库的客户机/服务器模式的电网故障仿真培训系统互操作性差,移植困难。在传统的二层客户机/服务器之间增加一层中间件能有效解决这一问题。本文引入的ADO技术是中间件的一种。ActiveX Data Obiect(ADO)是Microsoft有关高级数据库接口的策略,它能使开发人员与OLE DB和ODBC技术完全分离。本文对比了几种数据库的访问技术,介绍了ADO技术的特点和优越性,并给出了具体实例。

Application of ADO Technology in Power Network Fault Emulation Training System

The traditional power network fault emulation training system used client/server mode based on database is stiff and difficult to transplant. It is an efficient way to add a layer of middleware. ActiveX Data Object (ADO) is a strategy of Microsoft about the advanced database interface, it separate the programmer from OLE DB and ODBC. In this paper the author compares the several ways to access the database, introduces the features and advantages of ADO, and gives some particular examples.
