True.
All data expressible in M is expressible in R -- equally true.

This is when using the term "Data" within the mathematical worlds of M and R.

Now take the information about a typical problem domain in a business. Take an expert in R and an expert in M and have them immerse themselves in the domain and then prepare R and M models, respectively. It is my experience (i.e. sans proof) that a) more information will be encoded in M b) the information will be easier to retrieve from M and c) the implementation in M will be easier to modify than the one in R (and then for those who care about performance, given that is the biggest killer of software projects, M will likely also perform better -- oh, and then there's the difference in hard and soft costs associated with R & M ...)
