Do you usually read a little bit far? Analyze articles or design application architectures with minimal interaction with UML class diagrams. In fact, the most commonly used elements in UML class diagrams can be mastered in five minutes, so let's get to know them together:I. How the properties of a class are representedIn UML class diagrams, a class is represented

As a modeling language, the definition of UML consists of UML Semantics and UML notation.(1) UML semantic description precise metadata model definition based on UML. The meta-model provides simple, consistent, and general definitions for all

Maybe you are a newbie, maybe you have never touched UML. Maybe you have heard this word for the first time. It does not matter! Let's explain the UML in cainiao's eyes today. Maybe you have some reference for the first contact with UML. There is a more standardized definition in the Data. "The main achievement of the Research on object-oriented modeling technolo

UML for many people should not be a strange concept, the past two years, the UML has been more and more discussion. It seems that the subject of UML and I do not seem to have much of a relationship (it is language-independent, even if it is in itself a language-for communication). I'm here to talk about it for two purposes: 1.

This is a tutorial on the basics of UML; now that we're doing a project too tight, we haven't really done a real class-level detail design, let alone using UML to implement canonical modeling; This article is mainly about the relationship between several classes that I have been confused about before, Let's make it clearer when we really use UML for example class

(This is a long time ago wrote an article about UML, now put out and share with you) It is necessary to understand the basic knowledge of the association between classes and classes, as these relationships are like the cornerstone of our building and are the basis for orientation programming. There are six types of relationships in a class, namely, Association (association) relationships, Aggregation (Aggregation) relationships, combinatorial (composi

software maintenance.Tools include: 1, version control tools, 2, document analysis tools, 3, development information base tools, 4, Reverse engineering tools, 5, re-engineering tools, 6, configuration management Support Tools.Among them, the tools of reverse engineering are: program slicing, static analyzer, dynamic analyser, data stream Analyzer, cross-reference, Dependency Analyzer. Program Complexity metric 1. McCabe measurement method, 3 methods: (1) The number of regions in the flow graph

Objective With the continuous development of computer information systems, the system structure requirements more and more flexible, this flexibility is represented by the highly configurable program, may be the application of the workflow can be arbitrarily changed, the user interface can be arbitrarily changed, in the face of this constantly enhanced flexibility, it is impossible to modify the program code to achieve, The application system itself needs profound changes that require strong sc

Before formally designing patterns, it is necessary to introduce the relationship between UML class diagrams, because some tutorials, books, including my post, will use a lot of class diagrams to describe the relationships between the various classes. This is a very intuitive, minimalist way.Of course, the ability and energy are limited, the introduction of the UML here is only limited to a few common inter

In the process of learning UML, you often encounter UML class diagram relationship, here to introduce you to the UML arrows, lines represent the meaning, I believe that through the introduction of this article you have a more explicit understanding of the meaning of arrows and lines in UML.AD:This section to learn about UML
