基于ADO.NET数据访问技术的研究和应用

Research and Application of Data Access Technology Based on ADO.NET

通过几种数据访问技术的比较说明了ADO.NET技术的特点,并对ADO.NET数据访问技术的对象模型、访问模式进行了研究。在大型物理实验装置"神龙一号"数据库系统中使用ADO.NET技术实现了应用程序与数据库之间的交互,并给出了使用ADO.NET访问数据库的的步骤和源码。利用ADO.NET技术开发的数据库应用系统,满足了研究人员对实验数据进行在线、离线分析以及二次开发的要求。

By analyzing and discussing some data access technology the character of ADO.NET was explained,also object model and object system of data access technology based on ADO.NET was expounded.In ＂DRAGON-Ⅰ＂ database system the communications between application programs and database were achieved using ADO.NET technology,simultaneity the process and method of using ADO.NET were introduced by some codes in this paper.The database system based on ADO.NET meet the requirement of researcher who utilize the data on-line、off-line or later analysis.
