Question
What symbol(s) indicate a true/false condition on a systems sequence diagram?
Question 4
Select one:
- a. /
- b. [ ]
- c. { }
- d. *
Solution
Break Down the Problem
- Identify the context of a systems sequence diagram.
- Understand what symbols indicate conditions (true/false) in such diagrams.
- Evaluate the options provided.
Relevant Concepts
- In UML (Unified Modeling Language) sequence diagrams, conditions are typically represented by specific symbols that denote branching or alternatives in the flow of the system.
Analysis and Detail
- **Option a: / ** - This symbol is often used to indicate a guard condition for transitions in state diagrams, but not specifically in sequence diagrams.
- Option b: [ ] - Square brackets are commonly used to denote conditions in UML diagrams, including sequence diagrams. This is the format for specifying guards or conditions.
- Option c: { } - Curly braces might represent a set or grouping but are not standard for true/false conditions.
- **Option d: * ** - The asterisk is often used to represent repetition or iterations, not conditions.
Verify and Summarize
Upon analyzing the options, it is clear that option b: [ ] is the correct symbol used to indicate a true/false condition in systems sequence diagrams.
Final Answer
The correct symbol that indicates a true/false condition on a systems sequence diagram is b. [ ].
