Microsoft SQL Server 2012 offers customers the ability to run, grow and transform their IT to meet the most demanding business needs, and provides many benefits over comparable database products from Oracle, IBM DB2 and MySQL. Both IBM and Oracle only include a limited number of features in their base products and charge hefty prices for the "advanced" features, selling them as costly separate options, while MySQL is missing many key enterprise capabilities altogether.:
By contrast, SQL Server 2012 Enterprise Edition includes all the advanced features in the base product at no additional cost, significantly lowering the Total Cost of Ownership (TCO) for enterprise customers.
