What you model is what you build is what you execute...

In not so distant past I learned that 'Every thing happens twice, it first happens in mind'. Extending it further one might find it only natural that one solves a complexity in the way one models its solution, for e.g Sir Tim Burners Lee modeled 'The Internet' as a document sharing platform much of the things followed like HTML, browser etc. to solve the document sharing problem. It is only interesting to think what other ways Internet could have been engineered had he been from say database background. Not that, I'm about to show my creativity here to extrapolate the possibilities but just a point in case that our solutions are limited by our abstractions of the problem.
