Before the start of this chapter, the commercial application system development has gone through three stages: The first stage takes the computation as the center, the analysis design revolves the program The running efficiency, the algorithm merits, the storage optimization carries on. The 90 's university courses are all about that. The second stage takes data as the center, analyzes the design around the data flow, and simulates the business process with the data flow. This is the so-called

The first time I saw OO this concept was in a C + + book. There's an example of an animal in it. The concept of inheritance, polymorphism, etc. of animals, such as birds, mammals, insects, etc. Think of a college reading in C language inside a program logic diagram. I feel this oo is really amazing. And then contacted. NET. Start writing programs in the C # language based on the. NET platform. At first it f

Basic skills of OO programming (1) This series will talk about the basic skills of some OO programming languages. The basic skills of programming determine the code quality, programming ideas, and programming level, which is the top priority in the work. This article begins with an introduction to the basics and highlights of OO programming-ensuring abstract cons

The five principles of OO refer to SRP, OCP, LSP, DIP, ISP.Open Closed Principle is the most basic design principle in the Java world, which guides how we build a stable and flexible system.Defined:A software entity such as classes, modules, and functions should be open to extensions and closed for modification.Softeware entities like classes,modules and functions should is open for extension but closed for modifications.The opening and closing princi

Object-oriented Thinking of design patterns, design patterns OO [This article is my own learning notes. You are welcome to repost it, but please note the Source: http://blog.csdn.net/jesson20121020] Object-oriented (OO) thinking: 1. Consider classes Term2.

Originally wanted to share with you about the WCF related East, the first thought is SOA this thing, is now very fire, in the internet also saw a lot of this aspect of things, found that there are many with O. What the east, so put it together and share with you, but also for the understanding of these concepts and the understanding of SOA this stuff.Overall: Service Orientation,so represents a design concept, like object Orientation,oo, component-ori

The sum of these numbers for each non-empty set interval.Analysis: Use L[i],r[i] to represent the nearest approximate in A[i].Timeout code:1#include 2#include 3#include 4#include 5#include 6#include string>7#include 8#include Set>9#include Ten#include One#include A using namespacestd; -typ

Php: use serialization or session object to make oo php support object-oriented programming. This allows us to use classes and objects as much as possible during programming to simplify our program, reduces the workload of code maintenance. however, because the variables are released after the script is executed, the objects generated on this page may be in trouble when they are used on other pages. however, in many cases, some tasks are php: serializ

Software Engineering Tutorial" is actually a practice of YOURDONG, which provides two examples. Reading independently makes it easy to feel like a blind person.The two Chinese OO masters of "object-oriented system analysis" have their own values and are more suitable for China's national conditions. However, the content is still somewhat outdated. After all, it is based on "object-oriented analysis" and "object-orien

So far, we have a good macro-encapsulated code style, a basic class object structure simulation code, but never touched the core implementation of OO. This time, we finally need to enter the actual content-Object Inheritance and interface implementation.Memory layout of a single object In "the syntax of Crest-macro magic show", we implemented a simple object that contains member variables and member functions, as shown in. Buffer points to the charac

Every Ajax framework extends JavaScript and provides many common functions, enhancing the development efficiency of JavaScript. Here we will give a brief introduction to some common functions in Dojo. Because many common functions of dojo are used, these common functions are divided into five categories for your convenience. This article introduces the second part: common functions of object-oriented (OO) and package system. * Most of the content of t
