Web Database Systems Research And Practice

With the rapid development of information technology, the whole society is now linked with network communication. The increasing popularization of Internet and the rapid progress of Web technology brought the tremendous impact to DB technology. Under this background, Web-DB came into being with the combination of Web technology and database technology. Combining the advantage of Web technology and database technology, the Web Pages can be expand from static to dynamic pages which driven by database, and the development and using environment can be separated.We developed a Web-DBS-the Talents Database of Science and Technology in GuangDong. It aims to realize the sharing of talents of science and technology resources in GuangDong, and to improve the efficiency of talents of science and technology management This system is useful for the government departments to manage and trace the information of talents of science and technology in time, so that to strengthen the combination of production, studying and research.This paper mostly describes the research and realization of some key technologies in the talent database of science and technology in GuangDong, which include the system architecture, Web-DB accessing technology, application programming model, capability optimize and security.1) There are many kinds of architectures of Web-DBS, such as B/S architecture, B/S/S architecture and multi-tiered B/S architecture. We adopt B/S/S architecture in The talent-database of science and technology in GuangDong.2) We analyzed and researched Web-DB accessing technology and application programming model, and applied MVC model in the development of application system, adopted the Web-DB accessing technologies based on Java such as JSP, Servlets, JavaBean and JDBC, and realized the department of presentation layer, application layer, and data alyer of application.3) To improve the system capability, our system applied the DB connection pool technology which improved the efficiency of Web-DB access.4) The platform of Web-DBS-Intemet is open, so we researched the security of Web-DBS, and designed and realized the security of our system in many way.
