subject-oriented programming

programming Program composition that supports building

object-oriented systems as compositions of subjects,

extending systems by composing them with new subjects, and

integrating systems by composing them with one another

(perhaps with glue or adapter subjects).

The flexibility of subject composition introduces novel

opportunities for developing and modularising object-oriented

programs. Subject-oriented programming-in-the-large involves

dividing a system into subjects and writing rules to compose

them correctly. It complements object-oriented programming,

solving a number of problems that arise when OOP is used to

develop large systems or suites of interoperating or

integrated applications.
