In software engineering, a class diagram [1] in the Unified Modeling Language (UML) is a type of static structure diagram that describes the structure of a system by showing the system's classes, their attributes, operations (or methods), and the relationships among objects. The class diagram is the main building block of object-oriented modeling.
Classes can be derived from one or more existing classes, thereby establishing a hierarchical relationship between the derived-from classes (base classes, parent classes or superclasses) and the derived class (child class or subclass) . The relationship of the derived class to the derived-from classes is commonly known as an is-a relationship. [21]
Class diagram – A class diagram is a type of static structure UML diagram that describes the structure of a system by showing the system's classes, its attributes, and the relationships between the classes. The messages and classes identified through the development of the sequence diagrams can serve as input to the automatic generation of ...
A class diagram exemplifying the singleton pattern.. In object-oriented programming, the singleton pattern is a software design pattern that restricts the instantiation of a class to a singular instance.
Class diagram - a type of static structure diagram that describes the structure of a system by showing the system's classes, their attributes and the relationships between the classes. Classifier - a category of UML elements that have some common features, such as attributes or methods.
Classes have lifecycles which are modeled in Executable UML with a statechart diagram. The statechart diagram defines the states, transitions, events, and procedures that define a class' behaviour. Each state has only one procedure that is executed upon entry into that state. A procedure is composed of actions, which are specified in an action ...

Class-responsibility-collaboration (CRC) cards are a brainstorming tool used in the design of object-oriented software. They were originally proposed by Ward Cunningham and Kent Beck as a teaching tool [ 1 ] but are also popular among expert designers [ 2 ] and recommended by extreme programming practitioners. [ 3 ]
