What is Db2 for z/OS?

Db2 for z/OS is a relational database management system that runs on the IBM® zSystems platform.

A relational database is a database in which all of the data is logically contained in tables. These databases are organized according to the relational model. In a relational database, referential integrity ensures data integrity by enforcing rules with referential constraints, check constraints, and triggers. You can rely on constraints and triggers to ensure the integrity and validity of your data, rather than relying on individual applications to do that work.

Db2 is software that you can use to manage relational databases. IBM offers a family of Db2 products that run on a range of operating systems, including Linux®, UNIX, Windows, IBM i, VSE, VM, and z/OS.

z/OS is the main operating system for IBM's most robust hardware platform, IBM zSystems. Db2 for z/OS is the enterprise data server for IBM zSystems. It manages core business data across an enterprise and supports key business applications. Db2 for z/OS supports thousands of customers and millions of users.
