CDM with External DQ integration
I am new to CDM iMplementation & Have the Following Doubts.
1) DQ layer will clean data & Send it to OIC.
2) OIC layer will check for Dublicates in CDM. If Duplicates found, it will inform Data Steward & will not create a new record in CDM.
3) Else new record will be created in CDM & Receivables.
1) How to Handle updates? - Source system is very old & does not maintain Audit fields. So DQ layer will not know if this is a new record or an updated one. With the above Architecture, there can be a chance that updated value is received in OIC & CDM will identify as Duplicates.
