what is the best way to configure data warehouse, which is responsible for managing access information for more than one applications? Both Synchronization and (de)provisioning shall be performed on the data warehouse.

I've a central repository(target system) for many of my applications which keeps user accounts, roles (along with application mapping) and user-role association. I want it to integrate within D1IM v7, so that, for all applications, data synchronization data and provisioning of roles is done using D1IM to a single target. Any suggestion what would be the best way to implement it in D1IM.
