For some bad ideas about strong symbols, weak symbols, strong references, and weak references in C language, please correct them.First of all, I am very tragic. I did not know that C has strong symbols, weak symbols, strong references, and weak references before I read "Programmer self-cultivation-links, loading and li

Three major injuries to UML: A brother attacked UML and said that he had a personal understanding. For the original article, see the link below. At least the use case diagram, activity diagram, state diagram, class diagram, and time sequence diagram in UML are still very useful (I only use this degree at present ). The use case diagram mainly provides a large v

behavior of the system: the static structure defines the attributes and operations of important objects in the system and the relationships between these objects; dynamic Behavior defines the time characteristics of the object and the mechanism by which the object communicates with each other to complete the target task. UML is not a programming language, but we can use a code generator to convert a UML mo

This article mainly sorts out the UML modeling tool Visual Paradigm (VP-UML) official FAQ, hope to be helpful to visual paradigm users. Can the persistent layer generated in the VP-UML be redistributed? Does VP-UML support generating source code through diagrams other than class diagrams? Platforms supported by

Because of learning Java to do course assignments need to spend class UML diagram, online Search a lot of methods. This is the way to install the green plugin. Sometimes want to write our class to generate a UML diagram, is the code looks more clear, so we found a Java class under eclipse automatically generated UML diagram Plug-ins, find a lot, found green

This essay is well written, in PHP to explain the UML (or vice versa) can be said to be an innovation, through this article, I also found a good station: www.phppatterns.com. The translation of the UML terms comes from the UML User Guide (the Unified Modeling Language user Guide) that I am looking at. UML (Unified mod

Unified Modeling Language (UML) has rapidly become the de facto standard for building object-oriented software. This tutorial provides a technical overview of the 13 UML diagrams supported by Enterprise Architect. For a detailed semantic explanation of UML 2, see the new UML 2 tutorial.First of all... What is

UML-Deja Vu and uml-Deja vu When I saw the UML, I felt that it was very tall. There was such a cultural name, and there was a more meaningful explanation: design tools, there was a kind of visual feeling immediately. Software Engineering is a design idea, while UML is a design tool. It has not yet begun to learn. How c

integration-symbol integration and semantic integration. Symbol integration means that the model must fully express the view. Semantic integration is further refined by defining what information can be exchanged and how it can be exchanged. The inconsistency can be determined only after what and how. The Unified Modeling Language (UML), like other general software system development models, cannot meet the preceding semantic integration requirements.

The UML class diagram above the big talk design pattern: Class UML Representation The rectangular box of an animal indicates a class. A class chart is divided into three layers. The first layer displays the class name. If it is an abstract class, it is represented in italic; the second layer shows the class characteristics, usually the class fields and attributes; the third-layer display operat

Unified Modeling Language (UML) defines a series of standard symbols for describing object-oriented systems.

Simplified and graphicThe most effective simplified method used in modeling is graphics. Compared with a long string of complex commands, people find that the brain is easier to process graphics. Most modeling methods are built on Visual languages, such as UML, object-relationship diagram, or flowcha
