This category has seven sub-types: State Machine Diagrams (State Machines or State-chart Diagrams). The four new diagrams are called: communication diagram, composite structure diagram, interaction overview diagram, and timing diagram. UML Class Diagram. A Timing diagram is a special form of the Sequence diagram that is used to show the behavior of objects over a certain time constraint. A sequence diagram generally shows the interaction between objects in a sequential order. The best way to understand UML is to look at some examples of UML diagrams. The class diagram is the main building block of object-oriented modeling. An Interaction Overview diagram displays a sequence of behaviors and helps users simplify complex interactions (rectangular frames) into simpler forms in a system. Furthermore, the relationship between a Class and an Object in software development can be described as the relationship between, for example, the class "Food" and the brand "KFC" or the general class "User" and a specific username called "David" or what else. This may include the forward design and the backward design for different activities, roles, actors, and so on; Visualize Programming Language - Different types of UML diagrams in a certain system can be translated into code directly to save time for software or related application development; Business Analysis - In reality, the UML diagram can also be used to analyze the business sales pathway in order to improve customer service; The two most main categories of UML diagrams are the Structure UML diagram and the Behavior UML diagram. An activity represents an operation on some class in the system that results in a change in the state of the system. UML, short for Unified Modeling Language, is a standardized modeling language consisting of an integrated set of diagrams, developed to help system and software developers for specifying, visualizing, constructing, and documenting the artifacts of software systems, as well as for business modeling and other non-software systems.

The final result (different states) of the game can be different based on players' specific strategies. The objects are nothing but real-world entities that are the instances of a class. They describe both the static structure and the dynamic behavior of a system. 7. It has become the standard way to design and document software. The above UML object diagram contains two objects named Ferrari and BMW which belong to a class named as a Car. Interaction overview diagrams are a combination of activity and sequence diagrams. The purpose of class diagram is to model the static view of an application. Composite structure diagrams are used to show the internal structure, the behaviors of classifiers, and the relationships between classes in a system. Object diagrams describe the static structure of a system at a particular time. The site provides graphical notation reference and examples of all types of UML diagrams.
