Use cases in object-oriented software development
Klaas van den Berg, Mehmet Akşit, P.M. van den Broek · University of Twente Research Information · 1999
In this document we describe use cases and its role in the software development process. There is no precise semantics of use cases. Use case descriptions can be formalized with control flowgraphs. Based on this formalization, the use of the standard technique of sequence charts can be improved, in particular for the uses relation and the extend relation between use cases.
