Many times, we have seen people asking do we really need to build a data model where we just need to interact with downstream systems to get response?
Answer is absolutely NO!!
You don’t need to build a data model where you don’t need to deal with incoming data. If Pega plays a role as an intermediator between the systems to bring transparency and collaboration then you do not need a data model as it might limit your application scalability & extensibility.
Think about creating the data structure only when your application requires to know the data in details.
