The Object-Oriented Modeling (OOM) approach is used for developing the model of the focused case study i.e. Crises Management System. Our approach targets the requirements specification and design phase of the software development process. We choose to focus on the single system i.e. bCMS.
The method uses UML 2 collaborations for service structure and activity diagrams for both global behaviour (choreography) and local component behaviour (orchestration). The behaviour of each system component is designed as a composition of the roles it plays in different services.
