composite relationships. Generalization ): Dependency: for example, logwapper depends on log, The so-called dependency, the dependency program is relatively speaking, not necessarily because logwapper cannot "survive" without a log ". In the specific business logic, logwapper needs logs to assist with the completion of a specific task, which is also dependent. Class "recursion" relationship and "Triangle" Relationship Recursive relationships are self-contained relatio

directly with each other, then these two classes should not have direct interaction, and if one of the classes needs to invoke a method of another class, the call can be forwarded through a third party. The fundamental idea of this principle is to emphasize the loose coupling between classes, and the weaker the coupling between classes, the more beneficial the reuse, the more weakly coupled class is modified and does not affect the related classes. In the structure design of a class, each c

What is a simple Factory mode:By defining a class specifically, you are responsible for creating instances of other classes that typically have a common parent class. UML class diagram for simple Factory mode: The roles contained in the Simple factory model and the corresponding responsibilities are as follows: Factory class Creator: The core of the simple factory model, which is responsible for creating in

Overview A deployment diagram (deployment divisor) is used to display the physical architecture of software and hardware in the system. From the deployment diagram, you can understand the physical relationship between software and hardware components and the component distribution of processing nodes. The deployment diagram shows the structure of the runtime syst

extension (Extension) use case, and then extends it from the extension point (Extension points) declared in the base use case to make the base case more concise and more focused. The extension use case adds new behavior to the base use case. An extension use case can access the properties of the base use case, so it can determine whether to execute itself based on the current state of the extension point in the base case. However, the extension use case is not visible to the base use case.Examp

Activity Diagram can be used to model the dynamic behavior of the system, mainly to refine the use case, that is, the details inside the use case can be described in the form of an activity diagram. The activity diagram describes the sequence of activities, the flow of control between the main table activities, the internal processing-driven process, which is ess

class is responsible for coordinating other jobs. After learning about classes and class diagrams, I began to draw class diagrams. This is really a headache. When I was writing a document, I felt very eager to draw a UML diagram, because it was useful at that time, but now I have a chance, and I really didn't know how to start it. I also read the class pictures drawn by others, but they said that you sho

Before learning UML class diagrams, recommend a good website with lots of open source projects: Http://www.oschina.net/project. Also recommend an open source project: STARTUML, all of the following class diagram and the diagram between the classes are drawn with STARTUML. Let's take a sample before learning UML: Comme

Reading videos or tool books, including summaries, is in the theoretical stage. "The last word on the paper is superficial. I know that this is a must ." Now we are in the UML document stage, and it won't work unless we do it. I have done the "Data Center Charging System" before. To put it bluntly, I am blind. I have no rules to follow the feeling. The training solution provides the following explanation: "We have already done this because of the data

Recently has been learning the basic knowledge of UML, after watching the video, and did not have a good summary, in the process of drawing found a lot of problems, the following is the process of reading their own summary of the UML use case diagram of a little knowledge, share with you. First, the concept A use case diagram
