MS SQL Server
Microsoft SQL Server is a powerful relational database server developed by Microsoft. With its efficient OLTP engine, the technology is able to provide up to 30x performance gains for applications and up to 100x for data warehousing, allowing speedy access and analysis of data. It also provides unprecedented security due to the fewest (among all enterprise DBs) vulnerabilities detected over the last 6 years. Apart from that, Microsoft SQL Server works perfectly in hybrid (on-premises plus cloud) environments.
