Database management system (DBMS) is the software that manages a database. Though with different names (Microsoft, Oracle, MySQL, IBM DB2, Sybase) they help in the organization, storage and retrieval of information. The Database management systems market is worth more than $27 billion as of 2009 and is expected to reach $32 billion by 2013. Some of the special features of MySQL Enterprise 5.1 server include partitioning that helps manage very large databases and Event Scheduler to help create and schedule jobs.
