Study Notes
Use Cases
- Use cases describe interactions between systems and their environment
- Use cases do not describe internal workings of a system
- Use cases are typically depicted as ellipses in a use case diagram
Domain Model
- A domain model is a conceptual representation of the problem domain
- It represents concepts, behaviors, and rules of the problem domain
- A domain model helps in understanding the problem domain and identifies key concepts and relationships
Requirements Analysis
- Requirements analysis involves identifying and documenting stakeholder needs and expectations
- It involves understanding the problem domain and identifying functional and non-functional requirements
- Requirements analysis involves communication with stakeholders to gather requirements and validate assumptions
Interaction Diagrams
- Interaction diagrams show interactions between objects in a system
- Interaction diagrams can be used to model complex interactions and identify potential issues
- Interaction diagrams include sequence diagrams, communication diagrams, and timing diagrams
