Simple rules do define enterprise shared and sector data.

After discussing models of data sharing across enterprise users we want to make some rules to distinguish between sector data versus shared data. First of all we want to define sector data. Actually our enterprise data split into information worlds. Each information world contains data that serve the needs of certain professional workers group and act as a part of that professional group business logic. Such professional group could be finance peoples, human resource peoples, marketing peoples and so on.

From information world definitions you can easily map enterprise information into certain information world. Usually each information world, due to it business logic (workflow), has dedicate system to deal with that business logic. Therefore each information world data is managed by that system that handles information world business logic.

For mapping shared enterprise data you need detailed BPM’s (Business Process modeling) of your enterprise. The logic here is pretty straight forward, every data that participates in a cross group’s business process consider as shared data and should be access across enterprise users.
