Composite

Composite

  • A compositerepresents an entity as a whole made up of other entities that are considered its parts.

Composite in se

Composite In SE

  • Abstraction

    • High level languages

    • Models

  • Composite

    • Classes


Composite se vs others

Composite: SE vs Others

  • Other

    • Object Physical structure

      • hierarchical decomposition

    • Model ≠ Real object

  • SE

    • Any kind of decomposition

      • Structural, functional…

    • Model = code = application = Real object

Cadse

CADSE

  • Computer Aided Domain Specific Environment

    • Domain specific

    • Extend generic environments

      • IDE

      • SCM

    • Allow manipulating an application model

      • Conform to a domain model

  • A Domain is an area in which a number of stakeholders is repeatedly performing similar activities.

CADSE (Computer Aided Domain Specific Environment)


Domain model

Domain Model

  • System Model

    • Abstract, coarse grain view of a system

    • Come from SCM

    • Describes logical organization of product

  • Domain model = System model


Domain model example

<< A >>

<< A >>

Composite2

composition link

Composite

  • A composite is an item composed of all items that constitute the destination of a composition link starting from that item.

  • A composite must be such that, when closed, it can be safely used, for a given purpose, in place of the set of items it contains.

Composite mechanism

Composite mechanism

  • Closed a composite => remove its components.

    • Links are Resolved/Unresolved.

  • Closed a composite => close the composites it contains.

  • A close operation must ensure that build of the composite is OK.

  • Derived link mechanism.

  • Read Only mechanism.

  • Experiences

  • Conclusion and future works


Experiences

Experiences

  • Since 2006, daily used

  • Many CADSEs

    • Melusine, APEL, OSGi, iPojo, Think

    • DOCOSOC, FOCAS and CADSE

  • Usability

    • Composite builders are complex to define.

  • Implementation

    • Derived link decrease performances

    • Versioning management part is very complex


Experiences1

Experiences

  • Abstraction => 10 to 100 smaller

  • Point of view

  • Operational object => improved build perf

  • Model and semantics

  • Composite management

  • Experiences

  • Conclusion and future works


Conclusion

Conclusion

  • Model = operational high level software view point

    • CADSE synchronize model and artifacts

  • SE composites ≠ Other composites

    • Operational ≠ descriptive

    • Open/Close => abstraction, scalability

  • Composite aspects

    • Structuring, abstraction, scalability, operational, point of view, concurrent engineering


Future works

Future works

  • Implicit derived links => explicit

  • Switch from source to binary

  • Improve build mechanism
