(programming)

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.
