The ADO.NET xref:System.Data.DataSet is a memory-resident representation of data that provides a consistent relational programming model regardless of the source of the data it contains. A xref:System.Data.DataSet represents a complete set of data including the tables that contain, order, and constrain the data, as well as the relationships between the tables.
There are several ways of working with a xref:System.Data.DataSet, which can be applied independently or in combination. You can:
-
Programmatically create a xref:System.Data.DataTable, xref:System.Data.DataRelation, and xref:System.Data.Constraint within a xref:System.Data.DataSet and populate the tables with data.
-
Populate the xref:System.Data.DataSet with tables of data from an existing relational data source using a
DataAdapter. -
Load and persist the xref:System.Data.DataSet contents using XML. For more information, see Using XML in a DataSet.
A strongly typed xref:System.Data.DataSet can also be transported using an XML Web service. The design of the xref:System.Data.DataSet makes it ideal for transporting data using XML Web services. For an overview of XML Web services, see XML Web Services Overview. For an example of consuming a xref:System.Data.DataSet from an XML Web service, see Consuming a DataSet from an XML Web Service.
