What type of data is stored on the mainframe?
These days, the vast majority of Fortune 500 companies hold large amounts of critical business data on the mainframe, and much of this data may be stored in relational structures on Db2 for z/OS. However, there is also a wealth of data stored on non-relational mainframe data sources, such as Adabas, IMS, IDMS, VSAM, and flat files.
What are some examples of non-relational mainframe data sources?
However, there is also a wealth of data stored on non-relational mainframe data sources, such as Adabas, IMS, IDMS, VSAM, and flat files. Take, as a few examples, a bank ATM application or airline reservation system, both of which may be IMS-based (IMS being a hierarchical vs. relational data store).
