Summary This article analyzes the architecture mode of web applications and introduces the UML extension mechanism to model various objects in Web applications. This paper discusses the UML modeling and development methods for Web applications under the. NET Framework and applies them to a practical management system. The actual application shows that this method can reduce the development complexity, short

Http://www.uml.org.cn/oobject/200901203.asp UML practice-use case diagram, sequence diagram, state diagram, class diagram, package diagram, and collaboration Diagram Author: Randy Miller Source: Network The key to dealing with object-oriented problems is modeling. Modeling can abstract many important details in the complex world. Many modeling tools encapsulate UML (that is, the Unified Modeling Langu

-UML class diagrams are often used to describe the static structure between classes when describing the design mode. The purpose of this article is to allow the readers to understand the UML class diagrams and to figure out several relationships in the UML class diagrams. -In the subsequent design model learning process, only these two points are adequate.

In the past, I felt that I could not use UML. I didn't know what I was doing, that is, I knew there was a use case diagram, a class diagram, and a sequence diagram. At most, I wanted to express my needs, express the design to reach consensus. I recently worked on a project to know that UML is actually quite useful. From requirement to analysis, from analysis to design, from design to coding,

First, the nature of object-oriented abstract , when the system reaches beyond its processing power, we can abstract the scope we can deal with to commission abstract level , which allows you to build larger, more complex systems. 1, A way to map the real world to the object world. 2, A method of describing the real world from the object world. 3, A way to verify that the world behavior of an object reflects the real world correctly

When learning UML, you often encounter UML class diagrams. Here we will introduce the meaning of UML arrows and lines, I believe that you have a clearer understanding of the meanings of arrows and lines in UML through the introduction in this article. AD: This section describes the meanings of

meet their needs. They can't modify them and try again. How to analyze and export the requirements, and verify whether the design results meet the requirements. It is difficult for many experienced designers to express a reasonable derivation process.There is a gap between the real world and the object world-this gap is called abstraction, and abstraction is the essence of object-oriented. It is also difficult. The difference between OO design masters and cainiao lies in abstract capabilities.F

Do you know what the situation in UML is causing chaos? Know what kind of functionality is available in UML but not in Java? Do you know why we need another computer language other than Java? UML is not just a substitute for Java or any other language. UML is not just a substitute for Java or any other language.

representation of UML, the representation of a class is a rectangle, which is composed of three squares, namely, class name, class attribute and class operation. Class names and abstract methods in abstract classes are represented in italics. -Class Name: Capitalize first letter -Class Properties: Format for Visibility property name: Type = default value , such as-name:string There are four types of visibility: + Public -Private # protected * Pack

Class diagram is used to describe the classes contained in the system and the relationship between them, to help people simplify the understanding of the system, it is an important product of the system analysis and design phase, but also the system coding and testing important model basis. Let's talk about the composition of the class diagram, and we'll discuss the relationship between class diagrams in the next article.First, the composition of the class diagram1. General classis a

UML (Unified Modeling Language), the Unified Modeling language, is an open method for explaining, visualizing, building, and writing an open approach to the development of an object-oriented, software-dense system. UML presents a series of best practices that are validated for modeling large-scale, complex systems, especially at the software architecture level.Here first summarizes the UML's overall framewo

It also introduces the system-level debugging function.

diamond + solid ArrowCombination: The relationship between the part and the whole, and the life cycle is the same. For example: Man and hand7. Dependency (Dependency): indicated by a dashed arrow, for example: animals and oxygen8. Cardinality: The numbers at both ends of the line indicate that the class at this end can have several instances, such as: A bird should have two wings. If a class can have countless instances, it is represented by ' n '. Association, aggregation, and composition are

reality. 4) important systems must be processed using a set of independent models. In an object-oriented software system, to understand the system architecture, you need several complementary and chained views: use case diagram, design view, process view, implementation view, and implementation view. 1.3 Object-Oriented Modeling Oriented Algorithm Modeling becomes difficult to maintain after the demand changes or the system grows. Object-Oriented Modeling uses objects and classes as the mai

IOS design patterns-(2) UML inter-class relationships Before formally speaking about the design mode, it is necessary to introduce the relationship between UML class diagrams, because class diagrams will be widely used in some tutorials, books, including my subsequent articles, describes the relationships between classes. This is an intuitive and simple method. Of course, the capabilities and energy are lim
