Study Notes
Process Models
- Process models reveal how the system being developed is used in broader business processes.
- UML activity diagrams may be used to define business process models.
Interaction Models
- Modeling user interaction helps to identify user requirements.
- Modeling system-to-system interaction highlights communication problems that may arise.
- Modeling component interaction helps understand if a proposed system structure is likely to deliver required system performance and dependability.
- Use case diagrams and sequence diagrams may be used for interaction modeling.
Use Case Modeling
- Use cases were developed originally to support requirements elicitation and are now incorporated into the UML.
- Each use case represents a discrete task that involves external interaction with a system.
- Actors in a use case may be people or other systems.
- Use cases are represented diagramatically to provide an overview and in a more detailed textual form.
Sequence Diagrams
- Sequence diagrams are part of the UML and are used to model the interactions between actors and objects within a system.
- A sequence diagram shows the sequence of interactions that take place during a particular use case or use case instance.
- Objects in a sequence diagram represent something in the real world, such as a patient, a prescription, or a doctor.
Classes and Associations
- Classes and associations are used to model the structure of a system.
- In the MHC-PMS, classes and associations are used to model the system's structure.
Generalization
- Generalization is an everyday technique used to manage complexity by grouping entities into classes.
- In modeling systems, generalization is used to examine classes and identify common characteristics.
- In object-oriented languages, such as Java, generalization is implemented using class inheritance mechanisms.
