Philosophy
Computing systems may be modeled in VDM-SL at a higher level of abstraction than is achievable using programming languages, allowing the analysis of designs and identification of key features, including defects, at an early stage of system development. Models that have been validated can be transformed into detailed system designs through a refinement process. The language has a formal semantics, enabling proof of the properties of models to a high level of assurance. It also has an executable subset, so that models may be analyzed by testing and can be executed through graphical user interfaces, so that models can be evaluated by experts who are not necessarily familiar with the modeling language itself.

Famous quotes containing the word philosophy:
“It was fit that I should live on rice, mainly, who loved so well the philosophy of India.”
—Henry David Thoreau (1817–1862)
“The result of civilization, at the Sandwich Islands and elsewhere, is found productive to the civilizers, destructive to the civilizees. It is said to be compensation—a very philosophical word; but it appears to be very much on the principle of the old game, “You lose, I win”: good philosophy for the winner.”
—Herman Melville (1819–1891)
“The sun of her [Great Britain] glory is fast descending to the horizon. Her philosophy has crossed the Channel, her freedom the Atlantic, and herself seems passing to that awful dissolution, whose issue is not given human foresight to scan.”
—Thomas Jefferson (1743–1826)
