The System.Data.SqlClient namespace is the SQL Server™ .NET Data Provider.

A .NET data provider describes a collection of classes used to manage connections between an ASP.NET Web application and a data store, such as a relational database or a hierarchical XML file.

This namespace includes the core SqlClient classes for specifically accessing and manipulating an SQL Server™ data source, and essentially consists of the SqlConnection, the SqlCommand, the SqlDataReader, and the SqlDataAdapter classes.
