A New Approach of Web Systems Modularity Increase Using Combination of Event-Driven Software Architecture and Relationship Mechanism Based on Message Passing

By increasing the rate of Web Systems sizes, other classic methods and styles of software production don't meet the needs anymore. In a big Web System which includes different elements and functions, the organizing method and the relations of these elements with each other and decreasing their complication is the main task of software architectures. In this paper, the authors are going to use software architecture style which is based on event-driven and relation mechanism based on Message Passing to determine a framework for internal and external structures of Web Systems and their internal parts to modularity increase of system. In fact, the authors try to provide a modular frame for Web System which divides it to two parts of core and broken independent modules and then design a structure according to the architecture based on event driven for these parts. The authors also want to use message exchange method with the structure based on XML to create relation and exchange Information among different modules with each other as well as system core which finally can improve system quality features such as security, modularity, extensibility, reusability and interaction between system haste and modules. Along with systems production based on a concrete and integrated frame, the authors can obtain a suitable efficiency in modular Web Systems.
