software Improving productivity and quality with domain-speciﬁc modeling BY JAMES L. HAMMOND s calls for increased software development productivity continue to mount, organizations are constantly searching for effective ways to satisfy the demand. Domain-speciﬁc modeling (DSM), with its capacity for automated full code generation, is achieving increased attention as a proven approach that achieves this productivity goal, while also improving quality. This article will introduce the fundamental concepts and beneﬁts of DSM, and discuss the implementation of a DSM language for the development of IP telephony services using the latest release of MetaEdit+. Domain-speciﬁc modeling is a model-based software development approach that focuses on the use of visual models as primary artifacts in the development process. DSM raises the level of abstraction beyond normal programming languages by directly specifying the solution in a language that uses concepts and rules from the problem domain. Raising the level of abstraction has historically been the catalyst for signiﬁcant development productivity improvements (e.g. the move from assembler to third generation languages), and the abstraction rise that occurs with DSM is another jump forward. Once these high-level models are created, code can then be automatically generated from them using customized code generators. Code can be produced in any programming language or for any development paradigm. Existing platforms, libraries, components, and legacy code can all be effectively utilized during the generation process. While it certainly is possible, DSM does not require that all code is generated from the models – but it does take the position that anything modeled by the modeler should generate complete code that does not need to be changed manually afterwards. The generated code is functional and efﬁcient– ideally looking like the code handwritten by the lead developer that deﬁned the generator(s). DSM helps to hide the implementation concepts from the models – A 20 APRIL 2008 | embedded systems design europe | www.embedded.com/europe 020-021-022-023_ESDE.indd 20 10/04/08 15:42:13 http://www.embedded.com/europe
