A method for developing software based on role modeling and RSI

Abstract

UML modeling has been widely applied in software engineering. Use Case method has become a common method to define and analyze application requirements. However, there are several disadvantages with Use Case method. To improve UML modeling, the technology of role modeling (RM) and requirement-service-interface (RSI) are introduced in this paper. In the end, an example of the development procedure of Internet Bank is given to illustrate how to use these two technologies synthetically in the analysis and design of application systems. This method is very practical in financial systems based on Internet. © 2012 Springer-Verlag GmbH.
