A UML diagram can represent structural information, or general types of behavior. Structure diagrams help document architecture of software systems. There are many types of structure diagrams, One case is a class diagram that represents attributes and relationships. Another case is a component diagram that represents how components split into software systems. The third diagram is deployment diagram that describes the tools used in system implementations.
The fourth diagram is an object diagram that illustrates the structure of the model system. The last diagram is a package diagram that splits a system into logical groupings. Behavior diagrams represent what happens in the system being modeled. Like structural diagrams, behavior diagrams have a representation too, and cases as well. One diagrams is an activity diagram, which represents how the business works and operates. Another diagram is a use case diagram, that describes the functionality of a system, and the use cases dependencies among the use of cases. Another case is an interaction diagram, which provides an overview and represents communication diagrams. The last diagram for behavior structured diagrams, is state machine diagrams, which represent states and state transition.
