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:
“How can you tell if you discipline effectively? Ask yourself if your disciplinary methods generally produce lasting results in a manner you find acceptable. Whether your philosophy is democratic or autocratic, whatever techniques you use—reasoning, a “star” chart, time-outs, or spanking—if it doesn’t work, it’s not effective.”
—Stanley Turecki (20th century)
“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)
“Irish? In truth I would not want to be anything else. It is a state of mind as well as an actual country. It is being at odds with other nationalities, having quite different philosophy about pleasure, about punishment, about life, and about death. At least it does not leave one pusillanimous.”
—Edna O’Brien (b. c. 1932)
