Study Notes
UML Diagrams and Concepts
- A sequence diagram is a behavioral diagram in UML that describes dynamic aspects of the system.
- A "black box" process is a process whereby there are insufficient inputs to generate the output described.
- In UML, a data store is represented by a rectangle with a dashed horizontal line.
- An actor in a use case diagram is an external entity that interacts with the system.
- A generalization relationship between classes is represented by an open arrowhead symbol (↝) in UML.
- In a class diagram, a multiplicity of * (star) signifies zero or more instances.
Data Flow Diagrams
- Circles can be used to represent processes that take data inflows and transform them to information outflows in data flow diagrams.
Relationships
- A composition relationship indicates that there is a whole-part relationship between the participating objects, but the part object(s) cannot exist without a whole object.
Additional Concepts
- There are several types of flow of events, but "black box" is not one of them.
