Modeling of Login Procedure for Wireless Application with Interaction Overview Diagrams

Vera Plavšić, Emil Šećerov

In this paper we describe in details UML modeling of login procedure, which is a part of UserBarCodeReader application, developed for large stores and intended for use as a customer support during the shopping session. Login procedure is realized within access control system, in this case over a wireless network. Paper gives the whole modeling and implementation cycle of login procedure, from Use Case diagrams to the Java source code. Login procedure is modeled using interaction overview diagram, new in UML 2.0, which gives concise representation and divides complex sequence diagram into several smaller. The link between these diagrams is modeled with OCL postcondition and precondition expressions.
