I have a scenario where I want a Person Hub in my business vault where I merge and consolidate person records from a couple source systems to create a single view of customer/employee/advisor etc. There is a Party table in System A and a Person table in System B. There is a Venn diagram of overlapping parties where 80% are in both systems but some are only in System A and some are only in System B. We will be adding more party sources to this later.
How would you setup the business keys in a the Business Vault Person Hub in this kind of scenario? We don't have an MDM platform or registry yet.
