This article is about what UML class diagram dependencies are about. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

UML class diagram dependencies

Relationships between classes: dependency on Dependency, generalization of Generalization, and structural relationship relationship between objects (Association), representing the implementation relationship between specification and implementation in a class (Realization)

Using dependent Usage

First take a look at the dependency relationships used in the UML class diagram. Using: Use, declaring that using one model element requires the use of another existing model element, so that the consumer's functions (including invocation, instantiation, parameters, and sending) can be properly implemented.

Call call: declare a method by which one class invokes the operations of another class.

Parameter parameter: declares the relationship between an operation and its parameters

Send send: declare the relationship between the sender and the receiver of the signal

Instantiate instantiate: declares that an instance of one class is created with the method of another class

Abstract dependency Abstraction:

Trace trace: declare that there are some connections between elements in different models, but not as accurate as mapping

Refined refine: declares mappings between elements at two different semantic levels

Derived derive: declares that one instance can be exported from another instance. At the end of the introduction to abstract dependencies, let's take a look at authorization dependencies in UML class diagrams.

Authorization depends on Permission:

Access access: allow one package to access the contents of another package

Import import: allow one package to access the contents of another package and add aliases to the components of the accessed package

Friend friend: allows one element to access another element, regardless of whether the accessed element is visible or not

Binding depends on Binding:

Bind bind: specify a value for the template parameter to generate a new model element.
