dataset和DataApater
ADO.NET DataSet 是数据的内存驻留表示形式，它提供了独立于数据源的一致关系编程模型。DataSet 表示整个数据集，其中包含表、约束和表之间的关系。由于 DataSet 独立于数据源，DataSet 可以包含应用程序本地的数据，也可以包含来自多个数据源的数据。与现有数据源的交互通过 DataAdapter 来控制。
-dataset and data DataApaterADO.NET DataSet express the form of the presence of memory, which provides an independent data source on the relationship between consistent programming model. DataSet express the entire data sets, including tables, constraints and table relationships. Since the DataSet is independent of data source, DataSet can contain data from local applications, but also can contain data from multiple data sources. With existing data sources to control the interaction through the DataAdapter.
