Constraint-driven development

To obtain the full benefits of model-driven development (MDD) approaches such as MDA, a suitable level of abstraction needs to be chosen which enables the core functionality and properties of a system to be expressed, independent of programming language or implementation platform, so that this specification can be reused for a wide variety of different environments.This paper describes how constraints, together with UML class diagrams and state machines, can be used as a precise and platform-independent specification language. We describe the use of constraints in UML-RSDS and tool support for the synthesis of executable systems from constraints.
