the specification or interface defined in the target element Refine Adornments represent the relationships between different semantic hierarchies. Substiute The source element is an alternative to the target element. Trace We use this dependency to track things such as dependencies from requirements to classes, or how changes in a model are practiced in other models. Use The target element to be used when the source

In software systems, classes do not exist in isolation, there are various relationships between classes and classes, and UML provides different representations for different types of relationships.1.

First, the concept: Introduction to the basic concepts of UML: UML:UML (Unified Modeling Language) provides a unified, standard, and visual modeling language for object-oriented software design. It is suitable for describing the whole process of software design which is driven by use case and is architecture-centric.

UML Class Diagram Relations Daquan1. AssociationBidirectional Association:C1-C2: Refers to both sides know each other's existence, can call each other's public properties and methods.This is described in the GOF design pattern book: Although this relationship is applicable in the analysis phase, we feel that it is too abstract to describe the

I. Purpose It is used to describe the static structure of the system. In all UML diagrams, class diagrams are the most familiar to us. We may have seen them when we are not in contact with UML. Class diagram, as early as in vs2005, there is a small icon "View
