Study Notes
System Modeling Diagrams
- Use Case Diagram: represents the interactions between a system and other 'actors'
System Design Diagrams
- State Machine Diagram: used to model the behavioral aspects of a system
- Class Diagram: represents the static relationships between design entities
- Sequence Diagram: used to represent the synchronization and coordination of system activities
Notations and Diagrams
- Black Box Notation: primary purpose is to model a system without considering its internal workings
- Composite Structure Diagram: described as being more concerned with 'structure' and less explicitly related to any one viewpoint
- Architecture Style Diagram: related to an architectural style focused on transaction-based forms, such as Client-Server architecture
Data Flow Diagrams (DFDs)
- Primary Purpose: to model the flow of data through a system
- External Entities: components that represent an external source or sink of information
- True Statement: DFDs can be used to model systems at different levels of abstraction
- De Marco's Distinction: DFDs focus on the flow of data rather than the control flow of the system
- False Statement: DFDs are only used to model the internal workings of a system
- Potential Drawback: DFDs can become complex and difficult to understand for large systems
