Existing methodologies based on the request/response model for system software design, rooted in principles of object-oriented design, lead to tightly-coupled interactions, and lack coordination capacities. The publish/subscribe (P/S) paradigm is particularly suitable for loosely-coupled communication environment. A design of event and subscription models under an object-oriented environment was motivated by the idea of using P/S paradigm for an object-oriented environment. A compiler subsystem for object-oriented P/S Systems was studied. In the subsystem, its form, working process, and typical algorithms were analyzed from the point of object-oriented and technology of P/S paradigm separately. Experiment was simulated in the following two aspects: users model and middle code generation, and shows that using the P/S service improves the usability of P/S systems.
