UML Interaction diagrams

Interaction diagrams:
Interaction diagrams (mainly the communication and sequence diagrams) are used to model the dynamics among system objects (mostly in correspondence to a given class diagram). Commonly, each of the interaction diagrams realises a specific use case of the system.

Example 1: Communication diagram for teacher removal

 

Example 2: Sequence diagram for teacher removal

 

Example 3: Sequence diagram for student enrolment into a course
