See CPS-1434: VES Message to update CPS DB - Developer Wiki - Confluence (onap.org) for a dynamically maintained wiki for CPS DB update.
CPS DB provides a central database to keep track of Configuration of RAN and other elements. CPS Core DB is based on yang models. The CPS NCMP (Network Function CM Proxy) provides mapping and translation function to use CPS Core DB for a particular NF. There is also a Data Model Inventory (DMI ) plug-in which facilitates the identification of particular NF elements and their yang models.

As shown in the figure below, the primary model update can happen though DMI Plugin and NCMP and secondary model update still uses the CPS-E-02 interface which happens via CPS-TBDMT. Below is the sequence prepared for Network Slicing use case. We planned to make use of SDN-C for triggering CPS update for primary-model, as mentioned already. You might need to introduce a new module in place of SDN-C.
(Shankar) Update from 12/13 SON call discussion with CPS team (Toine Siebelink and Tony Finnerty ). It may be possible/preferred to collapse and combine steps 4 and 5 in the figure below and have DMI plug-in receive the VES message directly. This assumes the VES message has information to identify the attributes, and update them in an efficient manner. In this case, step 8 trigger to TBDMT will come from CPS NCMP.
