DataReader与DataSet对象之比较分析

Comparison and Analysis of the DataReader and DataSet Object

随着数据库技术在软件开发中的广泛应用,数据库访问技术在管理系统的设计中得到了广大开发人员的重视。通过对ADO.NET中经常用到的DataReader与DataSet数据访问对象的基本属性、方法以及应用环境的深入比较和分析,找出了他们之间的区别,同时给出了他们在实际应用中的程序设计案例,由此得出了DataReader对象适合在连接工作环境下使用,而DataSet对象更适合在非连接工作环境下使用的结论,同时给数据库开发人员提供有益的参考。

Along with the widespread application of the database technology in the software development, more developer attached importance to the database access technology in the management information system design. By the comparison and analysis of the DataReader and DataSet object＇s basic property, method and applied condition in the data access objects of ADO, NET, has discovered the difference of them, and simultaneously has provided the programming case of using them in the practical, thereout it can be found out that DataReader object adapts to the connection working condition, but the DataSet object adapts to t the non -connection working condition,and at the same time the database system developer can be provided the beneficial reference.
