Message Models vs. Data Models

In this episode Skayl jumps right into the deep end and starts discussing message models — and how they differ from data models. As software developers, we have spent years building messages to send between our systems. We high-five each other for clever byte-packing schemes that save 10% network traffic. We celebrate efficient code that marshals and de-marshals our data in fewer than six operations.

But how does all of this relate to data models? Do message models have a place in the data modeling universe? Are they the same thing? If not, how are they different?
