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 physical and logical DFD?
difference between physical and logical data flow diagrams.
What is the difference between dfd 0 and dfd 1?
dfd0 is a bigger scope in less detail than dfd1 which is much more detailed
The difference between context diagram and level 0 diagram?
they are not different they are similar as level 0 DFD represents the primary individual process in system at highest level it is also called context diagram. It describes the overall system at highest level describing which element is inside and which element is outside the system..... youngheart_riwaj@yahoo.com
What DFD depicts?
A Data Flow Diagram (DFD) visually represents the flow of data within a system, illustrating how inputs are transformed into outputs through various processes. It highlights the sources and destinations of data, as well as the interactions between different components, such as processes, data stores, and external entities. DFDs are useful for understanding system functionality and can aid in identifying potential improvements or issues within a process. They are commonly used in systems analysis and design.
How do you create DFD for solving general quadratic equation?
