I have found that there are sometimes differences in the way we identify an Object in Mainframe DB and the integrated apps i.e in Mainframe DB an object can be uniquely identified by 4 fields whereas in the Integrated applications, only 2 fields might be required to identify the same Object. This usually leads to incorrect Data issues and can be very tough to identify as only a part of the overall data is affected by these issues.
How can we attempt to solve this issue? IS there any platform/software which we can use to highlight such Data Model differences? All suggestions are welcome!
