Microsoft SQL Server 2008 ... "with high scores in database programmability,
security, availability, and application/data integration"

"... for applications that require the most-comprehensive DBMS features and
functionality, look at Oracle, IBM DB2 for LUW, Microsoft SQL Server, and
Sybase."

"Microsoft: The most aggressive DBMS vendor with a strong road map. Microsoft
has done reasonably well in the database business but over the past three years
has shown increasing focus and commitment to going after the enterprise market.
SQL Server 2005 and, more recently, SQL Server 2008 have enabled Microsoft to
take market share in moderately sized to large enterprises, delivering good
performance, scalability, security, and availability functionality. Five years
ago, hardly any enterprises ran multiterabyte databases with SQL Server to
support critical applications. Today, hundreds of enterprises are running
10-terabyte and larger transactional SQL Server databases."

"Suitability: SQL Server is known for its easy-to-use, simplified enterprise
DBMS and for delivering the best price-performance for most business
applications. Many enterprises like the breadth and depth of the packaged
applications SQL Server supports across various industries. In addition, SQL
Server 2008 offers strong support for unstructured and semistructured data.
Enterprises that want a cost-effective and easy-to-use enterprise DBMS should
look at SQLnServer."
