Learn moreĬomponent Diagram Component diagrams describe the organization of physical software components, including source code, run-time (binary) code, and executables. State diagrams are especially useful in modeling reactive objects whose states are triggered by specific events. State Diagram Statechart diagrams, now known as state machine diagrams and state diagrams describe the dynamic behavior of a system in response to external stimuli. In many ways, a communication diagram is a simplified version of a collaboration diagram introduced in UML 2.0.
They describe both the static structure and the dynamic behavior of a system. They're a special instance of a sequence diagram, except time is shown to increase from left to right instead of top down.Ĭommunication diagrams model the interactions between objects in sequence. You should use the same notation on interaction overview diagrams that you would see on an activity diagram.Ī timing diagram is a type of behavioral or interaction UML diagram that focuses on processes that take place during a specific period of time. They model a sequence of actions and let you deconstruct more complex interactions into manageable occurrences. Interaction overview diagrams are a combination of activity and sequence diagrams. Sequence Diagram Sequence diagrams describe interactions among classes in terms of an exchange of messages over time. Typically, activity diagrams are used to model workflow or business processes and internal operation. An activity represents an operation on some class in the system that results in a change in the state of the system. Learn moreĪctivity Diagram Activity diagrams illustrate the dynamic nature of a system by modeling the flow of control from activity to activity. Use Case Diagram Use case diagrams model the functionality of a system using actors and use cases. They can be used to test class diagrams for accuracy.Ĭomposite structure diagrams show the internal part of a class. Object diagrams describe the static structure of a system at a particular time. Package diagrams organize elements of a system into related groups to minimize dependencies between packages. Package diagrams are a subset of class diagrams, but developers sometimes treat them as a separate technique. Watch this short video about UML Class Diagrams They describe the static structure of a system. These diagrams are organized into two distinct groups: structural diagrams and behavioral or interaction diagrams.Ĭlass Diagram Class diagrams are the backbone of almost every object-oriented method, including UML. The current UML standards call for 13 different types of diagrams: class, activity, object, use case, sequence, package, state, component, communication, composite structure, interaction overview, timing, and deployment. To learn more about creating UML diagrams: The key to making a UML diagram is connecting shapes that represent an object or class with other shapes to illustrate relationships and the flow of information and data. It also renamed statechart diagrams to state machine diagrams, also known as state diagrams. The four new diagrams are called: communication diagram, composite structure diagram, interaction overview diagram, and timing diagram.
