Synchronous join
Definition
The point of convergence within a workflow following alternative, mutually exclusive paths.
Key Points
An OR-Join (Fig. 1) represents a point within a workflow where two or more alternative workflow branches re-converge following an OR-Split into a single common activity as the next step within the workflow. In contrast with an AND-Join, no parallel activity execution has occurred at the join point, therefore no synchronization is required. With an OR-Join a thread of control may arrive at the specific activity via any of several alternative preceding activities.
