Research On Commercial Website Based On XML And .NET Technology

As good means of transmitting data between commercial applications, XML technology is becoming popular in that it can store, transform, and transmit data in an efficient way.This paper is based on a hotel management web site that is devised by .NET. Applying XML technology, the author does deep research on the change and advantage of traditional commercial web site, which is accompanied by the new data expression style and developing tool.The main ideas and conclusion is as below:(1) Applying XML data in commercial web site, the author does research on the change of establishing data model from the devising point of view, contrives a data model that is based on XML and Browser/Server structure. This model, compared with tradional one, has great advantages: Reducing data flux of web sites, integrating data from different sources, enhancing the ability of groupwaring, expandedness and repeated usage.(2) Due to the popularity of relational databases, we study the bi-way transformation between the XML documents and relational databases. Furthermore, we discuss the way of transforming XML query expression into SQL query.(3) Based on the 3-tier web application structure, the author presents a new idea of 4-tier structure (B/S/D/C), which synthetizes the merits of B/S and C/S structure, and has practical value.(4)Basic knowledge of XML and the application of .NET developing platform are introduced. Web services, data management and securing problem are also be discussed.(5)We turned the researching ideas into practice, and developed commercial web site with .NET platform. With regard to the different functional needs, our devising throughtways are diverse, and we successfully construct the 4-tier structure web applications.
