| In UML or BPMN, the gateways are used as a decision points, to apply some conditional logic. There is a way how to easily remember how they work: Inclusive gateway - has "O" inside. It is used as a logical operator OR. Inclusive gateway is used to model decisions where one or more paths can be taken. Exclusive gateway - has "X" inside. It is used as a logical operator XOR. Exclusive gateway is used to model decisions where only one path can be taken. Parallel gateway - has "+" inside. It is used as a logical operator AND. Parallel gateway is used to model decisions where all paths are taken simultaneously. | |||||||||||
