IBM Db2

Db2 is a Relational Database Management System (RDBMS) originally introduced by IBM in 1983 to run on its MVS (Multiple Virtual Storage) mainframe platform. The name refers to the shift from the then prevalent hierarchical database model to the new relational model. Although Db2 was initially designed to work exclusively on IBM mainframe platforms, it was later ported to other widely used operating systems like UNIX, Windows and presently in Linux. Db2 is an integral part of IBM’s information management portfolio. It is a full-featured, high-performance database engine capable of handling large quantities of data and concurrently serving many users.
