As you might have heard, AX 2012 has RTM'ed recently.
Now, the question you might ask is - OK, I have read the What's new in AX 2012, but that's not enough. The changes are too vast and I need more detailed information about them.
Well, worry no more :)
The information about AX 2012 is now available on TechNet, with a lot of new content still being added each day. And, finally, it's actually interesting to read. We now have various graphs, diagrams and tables that should help you understand each feature area a bit better.
Hint: The description of the functional modules of the application is under section 5. Use Microsoft Dynamics AX.
Enjoy!
