ADO. NET is an object-oriented class library used to interact with data sources. Generally, the data source is a database, but it can also be a text file, an Excel table or an XML file. Ado. Net supports two data access models: the connectionless model and the connection model. The connectionless model downloads data to the client and encapsulates the data to the memory on the client. Then, it can
