Datasets in Microsoft.Net


ADO.NET was designed to meet the needs of a new programming model: disconnected data architecture, tight integration with XML, common data representation with the ability to combine data from multiple and varied data sources, and optimized facilities for interacting with a database, all native to the .NET Framework.The ADO.NET DataSet is a memory-resident representation of data that provides a consistent relational programming model regardless of the source of the data it contains.

Datasets in Microsoft.Net - New DataSet
(Page 8 of 8 )

Once you’ve created your new DataSet with the appropriate structure, save your changes and close the XML schema designer. You’ve now created a DataSet schema file in your project. To add an instance of your DataSet to a designer, select DataSet on the Data tab of the Visual Studio .NET Toolbox just as you would if you wanted to add another component, such as a button, to a designer. Double-click on the Toolbox item, or drag-and-drop the item onto the designer or its components tray. Either of these actions will launch the Add Dataset dialog box, shown in Next Figure.

ASP.Net datasets

Now you are ready to use your dataset. In detail about operations that can be performed using Dataset and Typed Dataset will be covered in next part of this article.
