Technical Study Of Web Site Modeling Based On XML

Web has become the main platform for the exchange of enterprises payment. As the complexity and scale of web application increasing, the web needs a systemic method and model support to support it. The web site that contains mass data can be viewed as the data collection of one field. And this data collection has the character of web, that is the link between the data and the representation of these data.Web site is the abstract description of these data collection. As the development of the XML technology, using the XML as the description language of these data collections has the benefit to do nothing with language and easy for program processing.In this paper, the author brings forward a web site modeling method that bases on XML. This method is to use XML as the web describing language, and model a web site from four layers. It divides a web modeling work into the four layers work and the four layers describe different part of one web site. The four layers are the Semiticmodel, the structure model, the navigation model and the representation model. The structure model is also called the ER model.We can use different method to describe every model. In this paper, we use the OWL language or RDF language to express the Semitic model. The ER file is used to describe the structure model. And the navigation model is described by XML; the representation model is described using XSL.After the introduction of every model, we start to study the relationship of these four models. We can get the structure model from the semantic model. When designing the navigation model, we must use the structure model to show the structure of the database. The structure model can also be used to generate the database automatically.When the navigation file generated, we can parse this file to generate the XSP code that runs on the web server. After the XSP file and its XSL representation file are put on the Cocoon server, we'll get a web site.This paper also provide a web modeling tool to help useless modeling a web site using the method of this paper. The modeling tool of this paper can support the cycling of a web site development. And the XML based method also provides a new way of integration different applications.This paper involves the study of software engineering, database, artificial intelligence, XML and etc. It brings forward a web modeling method by way of delimitation. It also provide a modeling tool based on themethod of this paper. The web site developed using this method has the merit of easy reading and maintenance.
