Some basics of ADO.NET

ADO.NET is an evolution of the ADO data access model that directly addresses user requirements for developing scalable applications. It was designed specifically for the web with scalability, statelessness, and XML in mind. ADO.NET uses some ADO objects, such as the Connection and Command objects, and also introduces new objects. Key new ADO.NET objects include the DataSet , DataReader , and DataAdapter . The important distinction between this evolved stage of ADO.NET and previous data architectures is that there exists an object -- the DataSet -- that is separate and distinct from any data stores. Because of that, the DataSet functions as a standalone entity. You can think of the DataSet as an always disconnected recordset that knows nothing about the source or destination of the data it contains. Inside a DataSet , much like in a database, there are tables, columns, relationships, constraints, views, and so forth. A DataAdapter is the object that connects to the datab
