NTO has multiple systems across its enterprise landscape including salesforce, with disparate version the customer records. In salesforce, the customer is represented by the contact object. NTO utilizes an MDM solution with these attributes: 1. The MDM solution keeps track of customer master with a master key. 2. The master key is a map to the record ID’s from each external system that customer data is stored within. 3. The MDM solution provides de-duplication features, so it acts as the single source of truth. How should a data architect implement the storage of master key within salesforce?
