UML – A Part of an Interlocking System Development Process
The analysis of functional requirements and their definition presents a very important task in the development of software of an interlocking system. If the UML-based modelling is used, then specific rules and conditions of use need to be defined with respect to the application field, already existing default assumptions, given goals, and target platform properties that will consequently implement the software. This paper deals with the use of a multiple inheritance during the software development with the help of IBM Rational Rhapsody development environment. The specific problems that could lead to ambiguity are explained, since they often lead to systematic failures, and recommendations on how to correctly use the multiple inheritance are proposed.
