A swimlane activity diagram looks like this. It depicts all of the events that take place during the college management process flow. There are four swimlanes in the diagram, each with a separate data category. We got the admin section in the first lane. In the first lane, it lists all administrative tasks. Each component of the school information system is represented in the second lane. All of the actions are still connected with lines and segregated into lanes, as in a flow chart.
