ODBC is generic one & useful for times when the underlying database might change like Oracle database to a SQL server database like wise. The SQL Server Native client driver has been proven to be much faster & you can access only SQL DB..

Jaganathan Bantheswaran · Answer

What you mean by directly connecting to SQL Server? If you want to access the DB, then you should have drivers [mostly dlls] & use one of the following way. .NET Framework Data Provider for SQL Server: Provides data access for Microsoft SQL Server. Uses the System.Data.SqlClient namespace. .NET Framework Data Provider for OLE DB : For data sources exposed by using OLE DB. Uses the System.Data.OleDb namespace. .NET Framework Data Provider for ODBC: For data sources exposed by using ODBC. Uses the System.Data.Odbc namespace. .NET Framework Data Provider for Oracle: For Oracle data sources. The .NET Framework Data Provider for Oracle supports Oracle client software version 8.1.7 and later, and uses the System.Data.OracleClient namespace. EntityClient Provider : Provides data access for Entity Data Model (EDM) applications. Uses the System.Data.EntityClient namespace. .NET Framework Data Provider for SQL Server Compact 4.0: Provides data access for Microsoft SQL Server Compact 4.0. Uses the System.Data.SqlServerCe namespace. For detailed info, http://msdn.microsoft.com/en-us/library/a6cd7c08%28v=vs.110%29.aspx
