Design And Implementation Of User Management System And Public Access System For Knowledge Sharing System-POWAZI

POWAZI, knowledge sharing web system, can provide user with a tool which helps user with collecting and packing up the interesting data and information. It can also provide user with a share and communicating platform. We design the web system with Unified Modeling Language. We use the Use Case Diagram, Collaboration Diagram and Class Diagram of UML in the total design and the particular design. We design the database with MySQL and divide the database into table by classifying their business function. The web system uses Java 2 enterprise edition developing frame Strats+Ibatis+Spring to implement. Struts groupware is applied to the expression layer implementation. Ibatis groupware is applied to the data persistence function implementation. Spring, as a small J2EE frame, is applied to combining the expression layer groupware and the persistence layer groupware. POWAZI—knowledge sharing web system is divided into several subsystems, user management system, public access system, log system, rank assessing system. The aim of applying subsystem is to improve the agility and extend ability of the system. Once there is a requirement alteration inevitable, we can minimize the alteration of the system and minimize the infection brought about by the alteration of the class, the object, the attribute, the method.The dissertation expounds about the user management system and the public access system of the web system—POWAZI. Design and realize the systems with the theory and methods of course developing for software engineering. It includes the requirement analysis, the total design, the particular design, the database design, the developing and implementation, the system testing. The dissertation also discusses about the theory and methods which are used in the design and the implementation course of the systems.
