CWM11 — Optimize Instance data values

  • Key: CWM11-89
  • Legacy Issue Number: 4482
  • Status: closed  
  • Source: Adaptive ( Mr. Pete Rivett)
  • Summary:

    The Instances (hence MultiDimensional) metamodel is very wasteful
    in requiring a separate DataValue object for each simple string slot value:
    this in effect doubles the number of objects for value-oriented schemas such
    as Dimension definitions (in MultiDimensional where DataValue is inherited
    into MemberValue). This is a problem for XMI files and their processing, but
    even more so for repository implementations which tend to have management
    overheads associated with each object. Moreover these DataValue objects end
    up being directly contained in the MemberSet for the Dimension, which surely
    was not the intention. This means that when navigating from the Dimension to
    process its Members one also has to filter out a large number of these
    unwanted Data/MemberValue objects.
