Database management systems
A database management system (DBMS) provides structures, processes, services, and tools for handling data safely, quickly, and efficiently.
It provides the underlying support for most data management strategies.
The Information Management System (IMS) product from IBM works in OS/390 and z/OS environments to provide unparalleled reliability and performance for large-scale data processing applications. Organizations all over the world depend on IMS to handle massive amounts of data, process huge volumes of transactions rapidly, and serve thousands of users simultaneously.
IMS provides a solid foundation on which you can build strategies for preserving integrity, improving availability, and conserving resources. Despite the general reliability of IMS, you still need to develop a dependable recovery strategy.
