Object diagram
This diagram represents the state of classes in the system and their relationships or associations at a specific point of time.

State Diagram
This diagram represents different states that objects in the system undergo during their life cycle.

Sequence diagram
This diagram is used to explore logic of complex operations, function or procedure. In this diagram, sequence of the interactions between the objects is represented step by step.

Collaboration diagram
This diagram groups together the interaction between different objects.

Activity diagram
Activity diagram gives detail view of the business logic.

Deployment diagram
It shows deployment view of the system. It shows how hardware and software works together to run system.
