3.2. Process Nodes
Executable processes consist of different types of nodes which are connected to each other. The BPMN 2.0 specification defines three main types of nodes:
Events
The start of a process and the end of a process are both types of events. Intermediate events indicate events that could occur during the execution of the process.
Activities
Activities are actions that need to be performed during the execution of the process.
Gateways
Gateways are used to define paths of execution through a process.
