Dependence: A change in one thing can cause another to change. Descriptive: Dashed + solid triangle or dashed + solid arrowAggregation: A special association that describes the combined relationship of a whole and a pa

In UML class diagrams, the following relationships are common: generalization (generalization), implementation (realization), Association (association), Aggregation (Aggregation), composition (composition), dependency ( Dependency). Can be used in the PowerDesigner software, relatively simple. 1. Generalization (generalization) Generalization relationship: An inheritance relationship that represents a general and special relationship that specifies ho

1. Inheritance relationship (generalization relationship) Description: The inheritance relationship is a subclass (derived class) that inherits the parent class (the base class), or the child interface inherits the parent interface's relationship. The subclass object "is a" parent object, such as a bird is an animal. "UML Diagram": Diagram: Animal is the parent class, Bird class, Fish class, dog class inherit the animal class, they not only inher

First, in the analysis phase , the user's needs are described by the UML model. Second, in the design phase , the introduction of the definition of the software system in the technical details of the class (such as processing user interface, database, communication and parallelism problems such as the Class). Third, in the implementation phase , the object-oriented programming language from the design phase of the class to convert to actual code. T

1.UML Modeling A system development approach should be built by modeling language and development process groups. The modeling language is the representation symbol of the design, and the process is the step that describes how to develop it. The development process of UML includes requirements acquisition, system analysis, system design, realization and test 5 steps. First Stage Requirements acquisition

function requirements of the first submodule are completed. 9. Withdrawal sub-requirement module. 10. User Login Sub-module 11. Query the Balance sub-module. 12. User Interface module. 13. Drag all requirements to the functional requirements module to display. 14. Add a label to describe the name of the project--->ATM system functional requirements analysis. Two. Use case models 1. Add 1 Actor---> Users 2. Add 3 Use Case: query balance, user login, withdrawal The relationship bet

The three "allies" James Rumbaugh, Grady booch, and Ivar Jacobson created UML in 1995 and integrated their respective methods (OMT, booch development method, and OOSE) into a whole. In 1997, OMG used UML as an actual public standard. To a large extent, UML is a graphical language used to describe, record, design, and construct a solution. The powerful role of

In the process of learning UML class diagram, UML class diagram relation is a problem that must be mastered, and there are six kinds of relationships in UML definition: dependency, genus, association, implementation, aggregation and combination. The definitions and representations of the methods are described below.Introduction to

The 14th chapter uses UMLBefore exploring the details of UML, we should first talk about when and why to use it. The misuse and misuse of UML has caused too much harm to the software project.14.1 Why ModelingModeling is to figure out whether something is feasible. When models are much cheaper than real entities to build, we use models to study designs.14.1.1 Why build a software modelUML is used when we hav

UML State diagrams and activity diagramsThe Unified Modeling Language UML (Unified Modeling Language) is a non-patented third-generation modeling and specification language. UML is an open approach for explaining, visualizing, building, and writing an open approach to an object-oriented, software-dense system of artifacts. UM
