The four Objects from the .Net Framework provide the functionality of Data Providers in ADO.NET. They are Connection Object, Command Object , DataReader Object and DataAdapter Object. The Connection Object provides physical connection to the Data Source. The Command Object uses to perform SQL statement or stored procedure to be executed at the Data Source.

The DataReader Object is a stream-based , forward-only, read-only retrieval of query results from the Data Source, which do not update the data. Finally the DataAdapter Object , which populate a Dataset Object with results from a Data Source . The following link shows how to use these Objects in ASP.NET applications.
