Microsoft Dynamics AX 4.0 data model overview

I have great news for you, readers :)
Recently, on an internal Microsoft discussion group, I received a nice document with an overview of the data model for Dynamics AX 4.0.
After permission was received to publish this document to an external audience, I uploaded it to my personal web-site, so that all of you can download it at a convenient time.

The link is below. Enjoy!
