  2. Modelling in domain terms vs. modelling your code Map to code, implement Assembler Map to code, implement Code Generate,Add bodies Map to UML UML Model No map! Generate DSVLModel Components and code DomainIdea FinishedProduct Solve problem in domain terms

  3. Converging research areas • Methods, CASE, metaCASE • 50% use no method, 25% standard method, 25% customised • Visual Programming Languages • Domain-specific approaches • Textual DSL, Visual DSVL • Product family engineering • Code generation • Generative & template programming • Models to code: mostly structural, behaviour from state charts • Components/patterns • Raise level of abstraction • Reuse by reference, not copy and paste • Pattern languages

  4. Main benefits of DSVLs • Fundamental productivity improvements (3-10 times) • Shorter intervals: Fast • Lower costs: Cheap • Better quality: Good • Faster change responsiveness • Manage changes in domain instead of code • Allows developers to design products with domain terms • Apply familiar terminology • Solve the RIGHT problems! • Solve problems only ONCE! • Leverage expertise inside the team • Put the expert’s knowledge in a tool • “Hide” domain complexity (DSVL includes domain rules)

  5. DSL Case Study: USAF • Development of message translation and validation system (MTV)* • Declarative domain-specific language • + code generators and customisation of components Compared DSL against component-based development: • DSL is 3 times fasterthan code components • DSL leads to fewer errors: about 50% less • DSL gives “superior flexibility in handling a greater range of specifications” than components * Kieburtz et al., A Software Engineering Experiment in Software Component Generation, ICSE, 1996

  6. DSVL Case Study: Lucent • 5ESS Phone Switch and several DS(V)Ls * • Reported productivity improvements of about 3-10 times • From several cases • From several DSLs • DSVLs out-performed DSLs • Shorter intervals between product releases • Improved consistency across product variants • “DSL should be used always if more than 3 variants” * D. Weiss et al, Software Product-Line Engineering, Addison-Wesley, 1999

  7. DSVL Case Study: Nokia • DSVL and related code generators for mobile phone* • Order of magnitude productivity gains (10x) • "A module that was expected to take 2 weeks... took 1 day from the start of the design to the finished product" • Focus on designs rather than code • Domain-oriented method allows developers to concentrate on the required functionality • Training time was reduced significantly • “Earlier it took 6 months for a new worker to become productive. Now it takes 2 weeks” * MetaCase, Nokia case study, 1999

  8. How to implement a DSVL Done a few times before! Expert (few) DSVL metamodel Code generation Component library DomainIdea FinishedProduct Easy! Generate callsto components DSVLModel Normal (many) Components

  9. Apply in software production • Develop applications using the DSVL infrastructure • Continuously evolve your DSVL • Domain & platforms evolve
