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:
“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)
“I am still a learner, not a teacher, feeding somewhat omnivorously, browsing both stalk and leaves; but I shall perhaps be enabled to speak with more precision and authority by and by,—if philosophy and sentiment are not buried under a multitude of details.”
—Henry David Thoreau (1817–1862)
“Why does philosophy use concepts and why does faith use symbols if both try to express the same ultimate? The answer, of course, is that the relation to the ultimate is not the same in each case. The philosophical relation is in principle a detached description of the basic structure in which the ultimate manifests itself. The relation of faith is in principle an involved expression of concern about the meaning of the ultimate for the faithful.”
—Paul Tillich (1886–1965)
