The goal of this lab is to complete an initial component model that will be the basis of the deployment.

Lesson outline

• The teacher recapitulates the principles of component-based design (slides 1-20).
• The teacher explains the Component Identification (slides 21-26)
• Students update their design class diagrams
  • All use cases have their scenarios reflected in the class diagram as operations of interfaces. Update specification of use cases if necessary.
  • All "management" classes  (often singletons) are transformed into interfaces.
• Students create an initial component diagram
  
  • All packages and interfaces of the class model appear in the component model as components and their interfaces
  • Add external systems and their interfaces (slide 28)
• The teacher briefly explains the Component Interaction and Component Specification (slides 31-57)
• Students specify contracts (pre- and post-conditions) of two interfaces so that the part of the class diagram looks like the one on slide 51. Choose them at your own preference. Use either OCL or non-structured (but clear!) text specification.
• Students define important invariants of two components in the component diagram
  • Focus mainly on the specification of the provided-required interfaces relationship (slide 55)
  • Use either OCL or non-structured (but clear!) text specification.
