The join waits for both to perform and continue. However, the Concurrent_Activity and result of decision between Activity 1 and Activity 2 (that merged into one output) are synchronize incoming concurrent flows. So, Activity 2 and Activity 3 are our alternate flows and only one of which will arrive. Why?: Otherwise, the join will wait for both flows. Merge should not be used to synchronize concurrent flows.Ī decision is used after a fork, the two flows coming out of the decision need to be merged into one before going to a join. Merge node is a control node that brings together multiple incomingĪlternate flows to accept single outgoing flow. Join nodes are introduced to support parallelism in activities. Outgoing edge and is used to synchronize incoming concurrent flows. Once you have a prescription, you go to an optical dispensary, where you select your frames and place the order for your glasses. The first step is to see an eye doctor who will give you a prescription. Join node is a control node that has multiple incoming edges and one Draw a use-case diagram and a set of activity diagrams for the process of buying glasses from the viewpoint of the patient.
