ADO.NET facilitates the communication between programming languages and data sources (relational database systems, text files, excel documents, etc.). ADO.NET is part of the .NET Framework. ADO.NET is considered to be a successor of the classic ADO, but there are several important changes between ADO.NET and ADO. ADO.NET is used to manipulate data in databases, such as Microsoft SQL Server 2000, Oracle, MySQL and Microsoft Access and other data sources (text files, Excel files, etc.).
