Introducing ADO.NET
ADO.NET is the .NET Framework area that provides the capability to access data from databases, and can be thought of as the .NET version of ActiveX Data Objects (ADO), which was the data access technology prior to .NET, based on the COM architecture. ADO.NET can be observed from two perspectives, known as connected and disconnected modes. It can access data from different data sources thanks to data providers.
