Study Notes
Data-Flow Models
- Data-flow models are useful for tracking and documenting how data associated with a particular process moves through the system.
- Data-flow models help in understanding how the system reacts to internal and external events.
Data-Driven Modeling
- Data-flow diagrams (DFDs) are used to illustrate the processing steps in a system.
- Sequence diagrams are used to show interactions between actors and the system, as well as between system components.
