1, what is UML UML class diagrams can quickly examine code structures. 2. Theme The use of UML class diagrams in Pycharm. 3. Preparation work (1) Pycharm version is 2.7 or higher (2) Installing the Python Interpreter (3) UML Plug-ins and UML class diagram plug-in installatio

of the system can make good use of the diagram. The symbols in the deployment diagram include the symbol elements used in the component diagram, and several symbols are added, including the concept of nodes. A node can represent a physical machine or a virtual machine node (for example, a mainframe node ). To model a node, you only need to draw a three-dimensional cube with the node name at the top of the

repetition, there is a list in a, which holds the B object's n references , that's it.Well, to here, already put the above diagram of the relationship is finished, I hope you can have some gains, I also spent a lot of time ah (drawing, generate code, write to the blog, alas, a sweat). But it's worth it if you can get a thorough understanding of these relationships in UML class diagrams. :)+++++++++++++++++++++++++++++++++++++++++++++++++++++In

OverviewTime series diagrams (Sequence Diagram) describe the chronological order in which messages are routed between objects, which are used to denote the order of behavior in a use case.The time series diagram contains 4 elements, namely the object (OBJCE), the Lifeline (Lifeline), the message, and the activation (Activation).Time series diagrams in UML are represented as two-dimensional graphs. Where the longitudinal axis is the timeline, the time

"By the way, I often see these class diagrams in some technical books. They are simple and easy to understand. I am confused with some labels. Otherwise, let me know ." Laruence: "In fact, I am familiar with this. I will give you an example to look at this figure, which includes the basic graph method in the UML class diagram ." UML class diagram example LargeBIRD: "First, you can see the rectangular box o

extension above. For example, if A and B have A "one-to-many" repetition degree, there is A list in A that stores N references of object B, that's all. Now, I have finished the class graph relationship above. I hope you will get something better. I have also spent a lot of time (drawing, generating code, writing to BLOG, alas, a sweat ). However, it is worth it if you can thoroughly understand the relationships of UML class diagrams. :) ++ ++ In

There are six kinds of relationships in UML definitions: dependency, generic, association, implementation, aggregation, and combination. The definition and presentation methods are described below. Dependency (Dependency): The change in element a affects element B, but the opposite is not true, then the relationship between B and A is dependent, B relies on A; the generic and implementation relationships are semantically dependent, but are described s

This chapter first introduces the history and present of UML, as well as the concept of object-oriented programming, and then describes how to construct an application using UML. It mainly consists of the following four parts: first, understanding the object-oriented mechanism and visual model. Second, understand the graphical labeling model. Third, understand the UML
