A process flow is a set of activities arranged in a sequence to perform a specific task(s). Combining various activities, that is, Source, Target, and Schema creates a process flow. After creating these activities, combine them to create a process flow.
The execution of a process flow is controlled by the Process Designer. The Process Designer starts the execution of process flow instances and all the activities present in a process flow. When the process flow is executed, data from the source is converted to the intermediate form and then it is dispatched to the target.
