Alloy (specification language)

From Wikipedia, the free encyclopedia

In computer science and software engineering, the Alloy specification language is a declarative language for expressing complex structural constraints and behavior in a software system. Alloy provides a simple structural modeling tool based on first-order logic. The mathematical underpinnings of the language were heavily influenced by the Z notation, although the syntax of Alloy owes more to languages such as Object Constraint Language.[1] Alloy is targeted at the creation of micro-models that can then be automatically checked for correctness. Alloy specifications can be checked using the Alloy Analyzer.

The first version of the Alloy language appeared in 1997. It was a rather limited object modeling language. Succeeding iterations of the language added quantifiers, higher arity relations, polymorphism, subtyping, and signatures.[2]
