Case study of PSA-MECEL
  • Routing system
  • Evaluate project results on:
    • Methodology
    • RT Profile adequation
    • Tools efficiency
    • Model exchange
    • Code generation
    • Validation capabilities
the uml 2 0 component concept
The UML 2.0 component concept

 It supports the specification of both

  • "logical" components(e.g. business components, processcomponents)
  • "physical" components  UML 1.4(e.g. EJB components, CORBA components, COM+ and .NET components)
  • A component is modeled throughout the development lifecycle and successivelyrefined into deployment and run-time
a two views component model
A two-views component model
  • A component has an external view(or. “black-box” view)by means of its publicly visible properties
    • Protocol state machine attached to ports/interfacesmay define the external view more preciselyby makingdynamic constraints in the sequenceof operation calls explicit
  • A component also has an internal view(or “white-box” view) by means of its private properties which are itsinternal classifiers and how they are connected.
today in u2 proposal 2 possible models
Today, in U2 proposal, 2 possible models
  • a component has Ports typed by Interface
    • components communicated together via messages going through their ports (like processes in SDL or capsules of "ROOM" model)
  • a component has directly Interfaces(required and provided)
    • components communicating also via messages but in this case,messages go through the interfaces themselves (like usual component model, e.g. CCM-CORBA Component Model, ... )

 still under construction …

… and should be completely revisited in incoming version !

  • Component definition 2 possible views:
  • “Black box” (= external view)
  •  set of interfaces
  • “White box” (= internal view)
  •  sub-system

Decomposition heuristics & component model

ER1 = Heuristics to ease decomposition of a system into a sub-systems model

ER2 = Model mappings to transform resulting sub-systems model into component model

- required & offered interface

- component connexions / association links

The ACCORD/UML RT-Component Model
  • ACCORD/UML component Model based on
  • UML2 component Model + RT_QoS

    • operations also with QoS specif.
    • receptions (signals) with QoS specif.

The ACCORD/UML RT-Component Model based on a MDA approach…

ER2 = These mappings take into account specified RT features of the sub-system model  PIM-to-PIM

ER3 = Mappings definition from the RT-Component Model of ACCORD/UML towards a platform model (e.g., RT-CCM model)PIM-to-PSM
