  2. Outline • Intro • Future MDA tools • Today’s MDA tools

  3. Part 0: MDA Intro

  5. Why Model Driven? • Productivity? • Portability? • Interoperability? • Maintenance and documentation? • Raising the level of abstraction! • Handling more complex systems

  6. MDA: a Revolution • 1960-1970: from assembler to 3GL languages • 2000-2010: from 3GL languages to modeling languages

  7. Future software development New roles for people involved: • Model creator (PIM analyst) • Transformation engineer (PSM creator) • Transformation definition developer • Language designer

  8. Software Development in 2015

  9. Part 1: Future MDA Tools

  10. Model Editor Model Validator Model Repository Transform Def.Editor Transform Executor Language Def. Editor Language Repository Code File Generator Code File Editor(IDE) Transf. Def. Repository Tools • What type of tools are there? MDA Connectivity Bus

  11. Requirements: Modeling Tools • Multi-user • Easy switch between visual / overview and textual / detail view • Early error detection / debug options • Code completion • Version control • Everything programming IDEs offer today

  12. Requirements: Language Tools Language Def. Editor: • See Modeling Tools • Extra: support for defining semantics Language Def. Repository: • See Transf. Def. Repository

  13. Requirements: TD Editor • See Modeling Tools

  14. Requirements: TD Repository • Classifications of Transf Defs • domain->GUI, domain->Web, domain->DB • Java->ER, UML->C# • Realtime process control, data entry • Easy access: library system tags • Quality assessments

  15. Requirements: TD Executor • General (QVT) executors and hard coded ones • Tuneable • I.e. value of x in “transform all strings in UML model to CHARVAR[x]” • I.e. on/off switch for aspects • Output = input for another executor • Open source and proprietary tools • Quality assessments of tools

  16. Requirements: General • Connectivity bus that supports interoperability • For instance, by providing a single XMI parser • Open standards supporting interchange • Modeling Languages (UML XMI is not a good example) • Transformation Definitions

  17. Part 2: Today’s tools

  18. Modeling tools • Not really multi-user • Few validation options • Break between overview and detail view    

  19. Language tools It’s beauty. Look’s like a house. • No support for expressing semantics

  20. Transformation tools • No repositories • Executors mostly hardcoded • Exception: ArcStyler • Little connectivity • Not possible to make a chain of executors • Little tuneability / Do It Yourself tuneability • Some open source tools available • AndroMDA, Octopus

  21. Conclusion • Raising the level of abstraction will improve • Productivity, portability, interoperability, etc. • Fulfilling full potential needs extra attention • 100% feasible • MDA is necessary to cope with more complex client demands
