First to identify the problem!
Are the definitions of your information properly understood? Does it mean the same thing to everyone? Or is there ambiguity? Do you need a common language to give a common understanding?
Within the MOD and in many commercial organisations legacy systems have written data/information to databases in isolation. With the amalgamation of organisations and the need to share and reuse data and information for business purposes these separate legacy systems also need to amalgamate in order to share data and allow date to be extracted for reuse as information. But there is a problem.
It is likely that the data in each separate legacy confirms to a different set of data standards and business rules. Also there maybe many different definitions and descriptions for the same data item depending on the system.
