> “You should also have a layer of software that lies on top of the message store that checks that any application above it which is trying to write a message, conforms to the agreed data dictionary. Otherwise, you can just write freestyle to the message store, which is what they were doing. There was no application interface in there, no agreed data catalogue or anything.” I think we can see that this sentiment has wider support in the software community - I would put many NoSQL database adaptions into this category. Another interesting development that shares this sentiment is frontend developers desire to bypass backend layer and get direct access to the data to "easy" and "speedup" their development.
