  8. Another companion paper

  9. Symphony vs. CacOphoNy ?

  10. Symphony and CacOphoNy : Same Goals

  11. Symphony and CacOphoNy : Same Goals

  12. Symphony and CacOphoNy : Experiences Distilled SIEMENS NOKIA DASSAULT SYSTEMES

  13. Symphony or CacOphoNy ?

  14. Symphony or CacOphoNy ? Just ask what is software architecture? 165 definitions of "software architecture" [SEI] "Architecture is a domain where everybody disagree with everybody" [SETRA2004 speaker]

  15. CacOphoNy, no Symphony Software architecture is about controlled CacOphoNy "Whether something is part of the architectureis entirely based on whether the developers think it is important. Architecture is a social construct because it doesn"t just depend on the software, but on what part of the software is considered important by group consensus." Martin Fowler

  18. Hypothesis Hypothesis Everythingis a model This is not Bézivin' Guest Talk

  19. Hypothesis "Everything is a model" (from Bézivin' Guest Talk) This is not Bézivin' Talk

  20. Hypothesis "Everything is a model" (from Bézivin' Guest Talk) Ceci n'est pas letableau de Magritte

  21. Hypothesis "Everything is a model" (from Bézivin' Guest Talk) Ceci n'est pas untableau de Magritte

  22. Hypothesis "Everything is a model" Ceci n'est pas untableau de Magritte

  23. Hypothesis "Everything is a model" Ceci n'est pas uneoeuvre de Kozuth

  24. Research Questions • Foundations of Model Driven Engineering? • Is MDE the next Software Engineering Paradigm? • Is MDE new? • Why it might work this time? National Research Project "Action Spécifique MDA" 7 University + 1 Research Institute Final report available soon at http://www-adele.imag.fr/mda

  25. CATIA software • 70 000+ classes • 3 000+ DLLs • 8 000+ "components" • 5 000+ "interfaces" • 800+ "frameworks" • xxx "solutions" • zzz "médias"… • ttt "products" A 7 years Case Study... • Dassault Système (DS) • World leader in CAD/CAM • One of the largest software companies in Europe • Pioneer with Microsoft in component engineering

  35. IEEE 1471 Megamodel IEEE 1471 IEEE Standard for Software Architecture • Nobody agreed about a standard definitions of architecture • Nobody really cared • Reverse engineering environment for a large component-based software engineering • Experience distiled => Metamodel driven methodology Ceci est l 'Architecture
