Role-based database design for managing complex objects and their relationships on the Web
There are many applications that have complex structures, complex relationships and dynamic changes. There is a trend to publish information and do work on the Internet. The traditional object oriented method cannot fulfill the need of such systems. We define a new process method. First we use the semantic network to describe the requirement of the application. Then role theory and the authorization tree are used to design the database of the system. This method is very distinct and easy to use in the development of Web-based applications.
