Ooa-ood-oop IntroductionI. OOA OOA: (object-oriented Analysis, object-oriented parsing method). is to analyze the problem according to the object-oriented thought after conducting the system business investigation in a system development process. There is a big difference between OOA and structural analysis. OOA emphasizes the analysis and collation of the material for the OO method based on the systematic investigation data, r

This article is translated from codeproject.ArticleRanking 3rd in the top articles, I think it is very good after reading it. I will translate it for the reference of students who do not want to read English. The wife of the author (Shubho), Farhana, plans to become a new software engineer (she was born and gave up later ), so the author tried to help her learn object-oriented design (OOD) based on her experience in software development and design ).

From: The principles of OOD What is object oriented design? What is it all about? What are it's benefits? What are it's costs? It may seem silly to ask these questions in a day and age when then ally every software developer is using an object oriented language of some kind. yet the question is important because, it seems to me, that most of us use those classes ages without knowing why, and without knowing how to get the most benefit out of them. Of

Although there are lights in the tunnel, the designer is worried that the tunnel will stop, so there is a sign at the entrance of the tunnel, Remind the pilot to turn on the light before entering the tunnel. But it made the pilots forget about the lights when they saw the beautiful scenery.Draw the under

[OOD-More C ++ Idioms] Inner Class)The purpose of an Inner Class is to implement multiple interfaces without having to inherit multiple classes. At the same time, it can naturally convert Up-casting ). Multiple implementations of the same interface are provided under a single abstraction. Alias motivation The virtual function Signatures provided by the two independent libraries through different interfaces may conflict. If you need to implement these

Interfaces represent common, so-called interface-oriented programming, which is to abstract the common denominator of different conceptsThe different points of these concepts are then packaged in specific classes, so that interface-oriented programming equals object-oriented programming.In fact, it's a concept. The IOC is going to postpone the dependency on detail to the runtime, completely independent of detail during coding and during compilationAOP is the typical "orthogonality" principle und

About the Ood in the Richter replacement principle, we familiar with can Cheung, no longer open, you can refer to the design pattern of the six design principles of the Richter replacement principle. Here are some attempts to discuss two forms and solutions that are often violated.The root cause of violation of the Richter scale substitution principle is the ambiguous relationship between the subclass and the parent. Our design succession relationship

OOD: Object-oriented design (object-oriented Design,ood) method is an intermediate transition in Oo method. Its main role is to further standardize the results of OOA analysis so that it can be directly accepted by OOP.OOP: Object-oriented programming (object Oriented Programming,oop, OO programming) is a computer programming architecture. One of the basic tenets of OOP is that a computer program is compose

system. After changing the role, congratulations! Your design has improved your control capabilities. Suppose you have completed the conversion. You are the chief designer of the highway system. While designing the road, you must solve the problem of our fuel. But you don't know when we need to refuel. What should we do? First, it is necessary to design necessary gas stations on the highway, and then, more importantly, put forward signs on the road so that cars can receive information and know
