【正文】 With the development and diffusion of Information Highway, people have been surrounded by the vast ocean of information. Due to the constant updating and increasing of information, the amount of information grows and expanses exponentially at a high speed, resulting in the “information explosion”. The “Information Trek” and “Information Overload” on the Inter have bee an increasingly serious problem. Information Push Technology (PUSH) is an effective solution to these problems. It achieves the “find people by information, service ondemand” by taking the initiative to push forward information to users. As a representative of the “PUSH” technology, RSS technology has been developing rapidly in the work news, emerce, BLOG, electronic publishing and other fields. The Information Push Technology, which is based on RSS, is an effective supplement to other push technologies, with the features of information editing, sharing and convenient transferring. The research goal of this topic is to realize the design of information subsystem which is based on RSS technology, using RSS technology and Struts framework, and to apply this system on the construction of bookpurchase portals. This paper firstly gives an introduction of the bookpurchase portal which has provided the research topic for this thesis. Next, it introduces the demand analysis and detailed design of the project database of this site. In Chapter 4, it provides a detailed analysis on the core technology, RSS, which is relevant to this topic. The analysis mainly includes the development process, structure, features and application models of RSS, and has designed the application on RSS in the project of bookpurchase portal, including the choice of class libraries, the production process of RSS Feed, system framework design and so on. Lastly, this paper introduces elaborately on the realization of several key issues in this system, including: the use of ROME RSS format to achieve the output, reading RSS Feed documents by browser and so on. There is also a system testing in the end.
