What is DataAdapter

DataAdapter is a part of the ADO.NET Data Provider. DataAdapter provides the communication between the Dataset and the Datasource. We can use the DataAdapter in combination with the DataSet Object. That is these two objects combine to enable both data access and data manipulation capabilities.

The DataAdapter can perform Select , Insert , Update and Delete SQL operations in the Data Source. The Insert , Update and Delete SQL operations , we are using the continuation of the Select command perform by the DataAdapter. That is the DataAdapter uses the Select statements to fill a DataSet and use the other three SQL commands (Insert, Update, delete) to transmit changes back to the Database.
