<
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.
