What is the difference between an activity diagram and a sequence diagram?

The Activity diagram represents the UML, which is used to model the workflow of a system. The Sequence diagram shows the message flow from one object to another object. The Activity diagram shows the message flow from one activity to another. Sequence diagram is mainly used to represent the time order of a process.

What is difference between DFD and flowchart?

In summary, DFD and Flowchart are two diagram types that help to develop software. The main difference between DFD and Flowchart is that DFD is a graphical diagram that represents the data flow of a system while a flowchart is a graphical diagram that represents the sequence of steps to solve a problem.

What is an activity diagram and what is its purpose?

An activity diagram shows business and software processes as a progression of actions. These actions can be carried out by people, software components or computers. Activity diagrams are used to describe business processes and use cases as well as to document the implementation of system processes.
