In software engineering, a class diagram 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. 在软件工程中,类图在统一...
For example, the Owner interface might specify methods for acquiring property and disposing of property. The Person and Corporation classes need to implement these methods, possibly in very different ways. Class Diagram Example: Order System

The class is a model element in the class diagram, and is a specialization of the EncapsulatedClassifier and the BehavioredClassifier. It summarizes a set of instances. Object instances within a class have the same characteristics (attributes) and behaviors (methods). They also have the same sem...
(the term for attributes or methods in a class). members can be classified as either instances or classifiers. classifiersare often recognized as static, meaning thatattribute values remain the same in all instances, and method invocation doesn't affect the instance's state. in comparison, ...

In a UML Class Diagram, entities are represented by a sectioned rectangular box identified by a role name centered in the top compartment. The middle compartment holds attributes (properties of the class) associated with each instance. Statics (data obtained through a function) are underlined. ...
If you have defined interfaces on the components in a component diagram, you can drag an interface fromUML Model Exploreronto the class diagram. In the class diagram, you can define the methods that the interface includes. SeeUML Component Diagrams: Guidelines. ...
Aristotle's pupil Theophrastus classified plants according to their uses and methods of cultivation. Little interest was shown in classification until the 17th and 18th cent., when botanists and zoologists began to devise the modern scheme of categories. The designation of groups was based almost en...
