databaselink - How can I connect database(MSSQL Server) with Mathematica?

Newly I started working with database(MSSQL Server 2012).

by google help, I created Table name as EmployeesList and also Insertedvalues into the table.

know I want to connect database with Mathematica.for that I seen documentation and founded OpenSQLConnectionfunction.but still not connected.

 databaseInstalizationLink="C:\\Program Files\\Microsoft SQL Server";  
 Needs["DatabaseLink`"];
 OpenSQLConnection[databaseInstalizationLink]

I seen JDBCfunction also but I didn't get it.
