  1. Allfusion™ Plex Putting Patterns to Work Data Management and Application Development Session Code: DA480SN Willem de Vries: Remia C.V. Simon Jasperse: Kiboko

  2. Agenda • Introduction • Positioning Allfusion Plex • Patterns at Remia • Weaving patterns: explanation and demo • Some pattern-examples and their use • Session Summary

  3. Introduction • Software Development at Remia • Development as main IS strategy • iSeries • Model-based Data-centric approach • Using 2E since 1990 • Allfusion Plex • Modernization of user interface • Multi-platform support • Logical “next step” from Allfusion 2E • Great support for abstraction: Patterns

  4. Agenda • Introduction • Positioning Allfusion Plex • … model driven • Patterns at Remia • Weaving patterns: explanation and demo • Some pattern-examples and their use • Session Summary

  5. Positioning Allfusion Plex – Model Driven • Model Driven Architecture: concepts • Defined by Object Management Group • Layered Models • Platform Independent Model • Platform Specific Model • Code Model • Definable Transformations from model to model • Based upon Model Object Facility

  6. Positioning Allfusion Plex – Model Driven (cont’d) • Model Driven Architecture: a picture

  7. Positioning Allfusion Plex – Model Driven (cont’d) • Model Driven Architecture: status • Important parts under development • Transformation language not standardized • No Action language • Tool support • Mostly ‘stub’-generation • Tools often Platform Specific: Java

  8. Positioning Allfusion Plex – Model Driven (cont’d) • Allfusion Plex and MDA • Proprietary model • Openness by Model-API and XML export • Platform Independence based on Variants • Generation ‘based on’ Plex Meta language • Websydian • Remia’s ‘early’ Model XML-export • Mature • Action Diagramming

  9. Plex: Advantage of Model Driven Allfusion Plex delivers today what MDA promises for a distant future……

  10. Agenda • Introduction • Positioning Allfusion Plex • … pattern based • Patterns at Remia • Weaving patterns: explanation and demo • Some pattern-examples and their use • Session Summary

  11. Positioning Allfusion Plex - Reuse • Reuse concepts in Software engineering • Modules: result of decomposition • Components: base for ‘re-’composition • Classes: inheriting properties and behaviour • Aspects: separation of concerns • Patterns: high level design experience

  12. Positioning Allfusion Plex: Aspects • Croscutting functionality • Logging • Tracing • Weaving implementation • AspectJ for Java-implementation • Currently submitted to Eclipse

  13. Positioning Allfusion Plex - Patterns • Originally ‘documentation’ of proven design • Erich Gamma, Martin Fowler, David Hay • Pattern-efforts mainly directed towards ‘cataloging’ • Patterns mostly have structure and behaviour • Currently popular concept • Attention for process (POAD) • Support in development tools starting off

  14. Positioning Allfusion Plex – Patterns(cont’d) • Building blocks of Patterns in Allfusion Plex • Framework: Foundation • Multiple inheritance • Edit Points • Replacement • Meta Language • Weaving-mechanism resembling Aspect Orientation • Joining based on ‘structure’ and ‘naming’

  15. Weaving Patterns – Multiple Inheritance .. is a .. Basic Entity Entity +Commit Download Entity Upload Entity .. is a .. .. is a .. Gambling Profit

  16. Agenda • Introduction • Positioning Allfusion Plex • Patterns at Remia • Weaving patterns: explanation and demo • Some pattern-examples and their use • Session Summary

  17. Patterns at Remia • Restructuring of Base Layer • Separation of Logical and Physical datamodel • Explicit structuring of Replacement objects • Patterns ‘ by design ‘ • Data-replication • User Managed Data • XML • Patterns ‘ by discovery ‘ • Combobox • Work-management: Documentflow, Proces/activity

  19. Agenda • Introduction • Positioning Allfusion Plex • Patterns at Remia • Weaving patterns: explanation and demo • Some pattern-examples and their use • Session Summary

  20. Weaving Patterns – Requirements Data Synchronization pattern • Exchange data between platforms • a-synchronous environment (off line account managers) • Data consolidation • handling data conflicts • match user (autonumber) keys • XML exchange • uses Remia XML pattern • isolate design changes from implementation

  21. Weaving Patterns – Design • Data Synchronization Pattern Upload Download

  22. Weaving Patterns – Demo • Implementing a Data Transfer Entity • Impact on functions and Dbase Structure • Meta coding to call all upload functions • Example GamblingProfit is a Download & Upload entity

  23. Weaving Patterns – Demo • GamblingProfit is a Basic entity

  24. Weaving Patterns – Demo • GamblingProfit is a Download entity

  25. Weaving Patterns – Demo • GamblingProfit is a Upload entity

  26. Patterns at Remia– DataPattern Demo • Implementation Demo http://pilat.free.fr/svgopen/

  27. Weaving Patterns – Design • Data Synchronization Pattern Upload

  28. Patterns at Remia - Results Data Synchronization pattern • Applied on 130 entities • Ease of use and maintenance • Exchange with external partners through XML

  35. Session Summary • Flexibility and patterns • Balancing between developer and user • Weighing reusability and initial investment • Application building • Strong need for Impact Analysis • Huge number of objects • Practical results • Fast implementation when needed • Small team delivers
