I've built both models (and more too) over decades. There are lots of questions one might ask before deciding between these two (or other) approaches: * Where does this team want the boundary between client and server in terms of user experience, server load and substantial UX interaction latency? * Can this frontend team independently plumb a changes all the way through the database? * Are backend teams always available for (or interested in) every minor update? * Are both halves of the application deployed on the same schedule? These are a handful of the first questions I'd ask before trying to push either solution at this point in time, the answers would likely lead to more questions.
