I wish! It's more of a loose collection of random business softwares in various states of abandonment. D365 CE is a platform for Sales teams to organize and track leads, quotes, contracts, etc. D365 BC is an ERP platform born out of the ashes of NAV, the core of which Microsoft bought decades ago. D365 F&O, D365 S&M, and others are various flavors of AX, another ERP platform Microsoft bought over a decade ago. They are direct competitors to D365 BC for some reason. None of these softwares can communicate directly with each other, and none allow direct access to the Azure SQL. Occasionally Microsoft will throw a bone towards integration stuff like DualWrite or Synapse or Fabric, but they can never seem to commit and eventually abandon those too.

I would actually be much happier if it was just crummy databases instead of an archipelago of rotting digital islands.

Frankly it's a bit like HyperCard.

One of the things we learned early on in trying to integrate a D365 system into our UI integration test automation, was that when you changed pages, the previous page was actually still in the DOM and so if you didn't update your locators to the new "context" or screen, you'd be trying to interact with things from two screens ago. I dunno honestly what they would have done without someone like me who could actually RE that. The guy that had seniority over me was completely lost.
