Use Case Diagram (UML)

Use case diagram consists of use cases, actors and relationships among them. It presents a user interaction with the system and defines the specifications of use cases.

Sequence Diagram (UML)

A sequence diagram models communication among objects in sequential order. It shows object, classes and actors involved in the scenario and exact order of messages. It consists of vertical lines which belong to lifelines and horizontal lines of messages.

Activity Diagram (UML)

Activity diagram is a behavior diagram, which shows a scenario using a flow of actions. It models a sequence of actions, decisions based on conditions, concurrent branches and various cycles.

Communication Diagram (UML)

UML Communication Diagram shows interactions in form of messages between objects and parts, which are represented by lifelines. Communication Diagram is a modified form of UML Sequence Diagram, but unlike it, its elements do not have to be ordered horizontally and may have any position in the diagram.
