Difference between activity diagram and dfd?
In data flow diagrams, the lines between "boxes" represent data that flows between components of a system. Because these only show the flow of data, they do not give an indication of sequencing.In activity diagrams, those lines are simply transitions between activities and do not represent data flow at all. They more represent the sequencing of activities and decisions. You can tell from these what order things happen in.
Difference between dataflow diagram and sequence diagram?
The purpose of a data flow diagram is to show you how the data flows through an information system. A sequence diagram shows you information regarding how the processes work together and in what order they operate.
