Extending the Value of Mainframe Data

 The vast majority of Fortune 500 companies hold large amounts of critical business data on the mainframe.  Much of this 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.   Take as an example a bank ATM application, or airline reservation system which may be IMS based.  IMS being a hierarchical vs.…
