This paper choosed Web, a subset of Internet, as its research object upon the widely developing requirements of application systems on Internet. It discussed some special problems in this set and compaired Web and legacy C/S system. Base on the discussion and comparison, several principles of Web-based application developing are proposed.The author developed IWDA (Integrated Web Database Architecture) . It includes Interpretation Layer, Secure Layer, Data Transform Layer, Query Layer and Application Layer, which cover most areas on Web-based application developing. It provides a higher developing platform for Web-based application developing.Meanwhile, the author proposed Fuzzy URL and rich FTP query technology and implemented it on IWDA. Fuzzy URL is compatable with standard URL, which could be used on standard common browsers. It extends semantics of standard URL, makes use of a lot of ignored file information, opens new information sources. It provides an assistant on resource locating and querying for URL, and could do fuzzy matches on the non-completed URI which was gave by users.The rich FTP query technology meets another kind of requirements, namely query on files in widely spreaded FTP sites. It provides richer querying and locating methods than original common FTP query services, such as Archie, and could help users find documents and files needed more accurately.The above two services are implemented on IWDA, but not limited to it. Its concepts and methods could be ported onto other systems and other Web servers.Besides, the author discussed methods of integration on Web and Database. The powerful data management and manipulation ability of database, as well as the widerange interaction ability of Web, provides new ways for Web extensions and new application fields of database on the Web. The author successfully stored content of Web sites into database and provided new methods for management and query for Web site data with the help of Fuzzy URL technology.The first chapter of the dissertation is introduction. In chapter 2 and chapter 3, the author introduced and analysed current research status on Web application development and database integration. IWDA is introduced in chapter 4, its objective, structure and implementation are also discussed. Fuzzy URL and rich FTP query technology are discussed in chapter 5 and chapter 6, respectively. In chapter 7, the author briefly introduces some ideas on integration of Web and database. Finally, the author summarizes the work and gives some future directions for fuither research.
