利用ADO技术对基于BDE架构的数据库应用程序的改造

The Change of Data Base Application Program Based on the BDE Structure by ADO Technolegy

数据库引擎是实现各种不同数据之间的相互存取的技术。随着数据类型的增加 ,数据库引擎也趋于复杂化 ,对其的选择将成为影响系统执行效率的关键因素。本文首先介绍了何谓BDE架构和ADO架构 ,并着重分析了二者各自的优缺点和适用场合 ;然后给出了一个如何从BDE架构向ADO架构转换的示例。

Data Base Engine is a Technology,which realizes the access of different kinds of data.With the increase of datatypes,Data Base Engine tends to complication and the selection of it will become a crucial factor that affects the executable efficiency of system.Firstly,this article introduces what are BDE frame and ADO frame,analysizes their advatages and disadvantages and their scope of application,then it present′s an instance about how to change from BDE frame to ADO frame.
