IBM Information Server, Version 8.1To integrate data throughout the enterprise, companies must access and respond to all the information that affects them. A significant amount of corporate data continues to reside in mainframes.
Mainframes play a key role in many enterprises. In some cases, the volume of data is too large to be moved off the mainframe, for example the data stored in very large databases (VLDB). In other cases, there are no migration paths, such as from IBM® IMS™. Mainframes can also be the most reliable platform upon which to run corporate data for day-to-day business functions.
Some data integration efforts, such as decision support, occur off mainframe systems to avoid tying up mainframe resources and to provide the fastest possible response times. The mainframe-connectivity tools in IBM Information Server are designed to help companies transmit data between mainframe systems and their data warehouse systems.
