subject
     
         In {subject-oriented programming}, a subject is
        a collection of {classes} or class fragments whose {class
        hierarchy} models its domain in its own, subjective way.  A
        subject may be a complete application in itself, or it may be
        an incomplete fragment that must be composed with other
        subjects to produce a complete application.  Subject
        composition combines class hierarchies to produce new subjects
        that incorporate functionality from existing subjects.
