About sequence diagrams

Sequence or event diagrams help create an overview of how a system works. Sequence diagrams show how all the different parts interact with each other over time, carry out the required actions, and complete processes. A sequence diagram descends from top to bottom showing a sequence of interactions and sequence diagram notations.
