This lesson introduces the ADO.NET

Almost all applications cannot be built without having interaction with a database which serves the purpose of data storage so the data can be retrieved later via either a SQL query or a database application. All those applications need a mechanism to connect with databases and ADO.NET serves that purpose.

Most of the nowadays .NET applications are dependent on ADO.NET but it was not like in the past when the .NET, developers were using data access technologies such as ODBC, OLE DB, and ActiveX Data Object (ADO).

When Microsoft introduced .NET they created completely new data access technology and new way to work with data, called ADO.NET. ADO.NET is actually a set of classes exposing data access services to .NET programmers, providing a rich set of components for creating distributed, data-sharing applications.
ADO.NET is an integral part of the .NET Framework and provides access to relational, XML, and application data. ADO.NET classes are found in System.Data.dll

This technology supports a variety of development needs, including the creation of front-end database clients and middle-tier business objects used by applications, tools, languages, and Internet browsers. Hence, ADO.NET helps connect the UI, or presentation layer, of your application with the data source or database.
