IBM's main database management system is DB2. It is powerful, and capable of handling extremely large databases. It is found on z/OS, Linux, Unix, Windows, System i (AS/400), and other places.

DB2 lends itself to business applications of all sizes, especially where flexibility in structuring the data is essential.

The language used to access data is SQL, which can be executed in many places, including in a COBOL program, through an on-line system such as CICS and IMS/DC, and on TSO/ISPF.
We have DB2 manuals, published books, and model program code. Click on a link at the left.
