Package diagrams is a combination of model elements that are represented in UML in a notation similar to a folder, each element in the system can be owned by only one package, one package can be nested in another, and a package diagram can be used to classify the related elements into a system that contains a package, chart, or individual element. In simple terms, we can directly understand the package as a
UML class diagram relationships include association, aggregation/combination, dependency, and generalization (inheritance ). The Association is divided into two-way Association, one-way Association, and self-Association. Let's take a look at what these relationships are and what their differences are. 1.

Unified Modeling Language (UML) use case diagramThe use case diagram describes a functional unit provided by the system. The purpose of the use case diagram is to help the development team understand the functional requirements of the system in a visual manner, including the relationship between "Roles" based on the ba

To learn UML, you must first learn 14 types of UML graphics. To learn graphs, you must first know what elements are on the graphs. [Note] This document is not a basic tutorial Of the use case diagram, but a graphical Summary of the use case diagram. The use case diagram is

Sequence diagramA sequence diagram is a form of an interaction diagram that shows the evolution of an object along a lifeline, and the interaction between objects over time is expressed as a message from the source lifeline to the target lifeline. The sequence diagram is a good indicator of how those objects communicate with other objects, what messages trigger t

The test is not based on the Java file automatically generated, but need to write their own dot syntax related code, such as, then give up1.UML Plotting
The interaction diagram is used to describe how objects interact in the system, that is, how a group of objects transmit messages. An interaction diagram consists of a group of objects and their relationships, including: What objects are required, what messages are sent between objects, what roles start a message, and how messages are sent in what order. Interaction graph classification: Interaction graphs

Component diagram, English name Yue: Component diagrams is used to describe the organization and dependencies between a set of artifacts, for the static implementation view of a modeling system, which can be executable programs, libraries, tables, files, and documents, and includes implementation information for logical classes or logical classes.

artifacts must be on the nodes that correspond, rather than being isolated. iv. Explanation of the deployment diagram(1) Node: the common name of the compute resource. Includes processors and devices. Where the processor is the hardware structure that can execute the program, such as computers and servers. A device is a service that is performed externally through an interface, such as a printer. Each node should give the appropriate tag description,
through the time sequence diagram, this process enables me to constantly modify and improve my classes and methods so that I can complete this learning stage. After this stage is completed, I think back to the whole process. I have benefited a lot from the reflection on the above experiences. If you have many clues when you want to solve the problem, but you do not have a main line, I suggest you write down all the clues, because your clues may be th
