Study of A Content Oriented Web Architectural Model

摘要

Many larger and complex web applications, such as e-commerce, ASP, portals, are content oriented, in which content is the critical elements and always under constant updates: content organization and presentation generally is required custom-tailored. Developing and maintaining such web applications demands a suitable model that can capture its features. For architectural descriptions address high-level aspects of the systems such as the overall organization, the decomposition into components, and the way the components interact, we first analyze the features of typical content oriented web application framework. In succession, this paper defines the types, structure, semantics, constraints of component and connector in our conceptual model of web content component, within which a web content component is regarded as an independent process unit performing necessary content organizing, processing and presenting functions. In component standpoint, a web application is regarded as a collection of web content components and some other service components providing certain content service. In this paper, our first concern has been to identify, classify, and support a variety of web content components and their connections, serving more effective development and maintenance of web applications.
