Excursion (2/3)Identification of Attributes

• Linguistic analysis of the problem description - extraction of adjectives and participles

• Rules of thumb:

  • attributes describe objects and should be neither class-valued nor multi-valued
  • derived attributes should be marked as such
  • context-dependent attributes should be assigned to associations rather than to classes

• The list of attributes is usually incomplete in the problem description
