Question 6

3 types of exceptions

Question 6

3 types of exceptions

Answer 6

1. internal:
   something goes wrong inside an activity, whose execution must be interrupted through an error event
2. external:
   something goes wrong outside the process, this is handled with message event
3. timeout: an activity takes too long and must be interrupted through a timer event

⇒ all these events are catching intermediate “boundary” events
