UML14 — Class "Model" is too prescriptive

  • Key: UML14-869
  • Legacy Issue Number: 1509
  • Status: closed  
  • Source: Anonymous
  • Summary:

    Summary: "Different Models can be defined for the same modeled system, specifying it from different viewpoints, like a logical model, a design model, a use-case model, etc."

    This statement is too prescriptive in suggesting that the modeled system should be partitioned into a logical model, a use case model, etc. The user may wish to partition the system using some other criteria, for example on functional lines, and may wish to "package" all the views for a particular function or facility within a single package. The partitioning suggested above can be easily obtained by using UML Packages named "Logical Model", "Use-Case Model" etc. Also note that class "Model" adds no attributes or associations to its superclass - it simply suggests a groping concept.

    Hence I recommend complete elimination of class "Model". The modeled system is simply a hierarchy of "Packages".
