class to know the properties and methods of another class, such as: teachers and students, the relationship between husband and wife can be two-way or one-way. Two-way associations can have two arrows or no arrows, and one-way associations have an arrow. "Code embodiment": member variable Arrows and points: solid lines with normal arrows, pointing to the owner In the picture above, the teacher and the student are two-way association, the teacher has many students, the student may also have man

An introduction to the graph of adjacency matrix The direction graph of adjacency matrix refers to a direction graph expressed by adjacency matrix. The above figure G2 contains a total of 7 vertices of "a,b,c,d,e,f,g" and contains " The matrix on the right of the above figure is a schematic diagram of the adjacency matrix in memory of the G2. A[i][j]=1 means that the first vertex to the J Vertex is an edge, a[i][j]=0 represents not an edge, while

Brief introduction Graph represents the relationship between points, in C # by the set of node objects to represent the point (Vertex), with the adjacency matrix (adjacency) to represent the relationship between the points. Here's a C # implementation. PS: This article is my review of notes, code comments are very complete. Don't spit the groove. Object that represents the point The following implementation code: Class Vertex { publicstring Data; Publicbool isvisited;

situation using MySQL to run better performance. The following MySQL installation diagram will give you a detailed description of how to install MySQL.The installation process, like other Windows installers, first appears in the Installation Wizard Welcome screenClick "Next" directly, continue, select the type of installationThere are 3 types: typical (typical), complete (full), custom (customized). Select "Custom" to install, then click "Next" Next,

In the nine diagrams of UML, the class and object graph are static graphs, and the reaction is the static process of the system. The class diagram is described earlier, and the following is the object graph. One, the object graph summary Two: Object Graph example The object graph is concrete, and the class diagram is abstract. such as the admin class in the class

This article mainly introduces the Python matplotlib implementation of the 3D diagram of the sample code, with a certain reference value, interested can understand Matplotlib can also draw 3D images, unlike two-dimensional images, drawing three-dimensional images mainly through the Mplot3d module implementation. However, using matplotlib to draw a three-dimensional image is actually shown on a two-dimensional canvas, so it is also necessary to load t

Method of generating logical structure diagram of river????? Sometimes in order to show the relationship between rivers, you need to generate a logical structure diagram of the river. This logical diagram is a bit like the logical structure of a wire network, to the need to show the basic structure and connectivity, without the need to show real spatial geographi

IntroductionBeef Brisket News Release system looks very feel, a line of feeling, after all, this is a system implementation of the tutorial, including a variety of details, although just looked at 10 episodes around, but deeply by the beef brisket Teacher's explanation of ideas brought in, especially some of the previous learning process neglected details, rice teacher said, At present, learning knowledge, follow-up learning will also be encountered. Really, learning is a circle, this feature is

UML Class Diagram Relations Daquan1. AssociationBidirectional Association:C1-C2: Refers to both sides know each other's existence, can call each other's public properties and methods.This is described in the GOF design pattern book: Although this relationship is applicable in the analysis phase, we feel that it is too abstract to describe the class relationship within the design pattern, because the association relationship must be mapped to an object

What is a class diagramClass diagram are mainly used to describe the structural design of a system. Class diagrams are also the most commonly used UML diagrams, with class diagrams showing classes, interfaces, and the static structure and relationships between them.2. Elements

In the painting ER diagram when looking for a more useful and professional point of the tool, looking for a half-day finally chose the seemingly less professional EA to draw ER diagram Briefly explain how the EA is implemented to draw ER graphs First, the Operation procedure 1. After creating a new project in the EA, select the model below 2. Then double-click the design Model on the right

In HR, the personnel organization structure is usually displayed in the form of Treeview. It gives people the feeling that the structure is not intuitive, the image is not displayed, and the size is relatively small, except for the name and cascade relationship, there is no other information. If you can export it to a Visio model diagram, that would be great? Next we will talk about how to export the organizational structure

I. Introduction to the time sequence diagram (Brief Introduction) Sequence digraphs are graphs that show interactions between objects. These objects are arranged in chronological order. The sequence diagram shows the order of message interaction between the objects involved in the interaction and their objects. The time sequence diagram contains the following mod

VS comes with the "view Class Diagram" function is a bit too weak to explode, can only generate inheritance relationships, even more basic association relationship can not be generated. Let's look at how to use the modeling tools EA to generate powerful class diagrams.The following example demonstrates the EA 11.0.1106 as an example1. New ProjectCreate a new project for File, new project. In the pop-up model patterns, select class, click OK, and then

. When the socket is closed, its host TCP sends a fin of its own. We point out in the diagram that this occurs when the application process calls close, but recognizes that when a UNIX process terminates either voluntarily (calling exit or returning from the main function) or involuntarily (receiving a signal to terminate this process), all open descriptors are closed. This also causes a fin to be emitted on any TCP connections that are still open. Fi
