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:
“A cosmic philosophy is not constructed to fit a man; a cosmic philosophy is constructed to fit a cosmos. A man can no more possess a private religion than he can possess a private sun and moon.”
—Gilbert Keith Chesterton (1874–1936)
“People who love soft methods and hate iniquity forget this,—that reform consists in taking a bone from a dog. Philosophy will not do it.”
—John Jay Chapman (1862–1933)
“My philosophy is that to be a director you cannot be subject to anyone, even the head of the studio. I threatened to quit each time I didn’t get my way, but no one ever let me walk out.”
—Dorothy Arzner (1900–1979)
