Rules
- Do not label start and end events
- A message flow is only needed when two entities are separate apart with other entities in between. If two activities are next to each other and linked with a process flow, you can attach the data object to the process flow without a dedicated message flow.
- Documents are always attached to the flow, not entity.
- In the scope of this unit, we don’t need anything in the external pool (vendor) and treat it has a black box. Any message flow sent to that black box points to its edge.
Layouts of BPMN
Simple layout
Consists no swim lanes and databases. It provides a quick overview of a process.
Swim-lane layout
Simple layout can be converted to swim-lane layout showing the activities performed by each resources.
Database interaction layout
Message flow in one direction, either retrieving or sending information from/to the database (the one on the slides is not good). You can have gateways in the database interaction layout.
