Programming with Models — Modeling with Code The Role of Models in Software Development

By: Dave Thomas

Abstract

Models provide a representation of partial truths about the software system, but only the actual code contains the whole truth. The art of programming is about managing the half-truths at higher levels of abstraction in a way such that they are just sufficiently correct to make progress, and sufficiently vague that they can be refined at the next level. Good software evolves like a book outline starting with an initial set of key ideas which are ruthlessly refactored into the final form. Model refinements and compositions can at best be captured as a set of annotated hyperlinks which describe the evolution of the software as a literate program.
