head first object oriented analysis and design

1. Explanations of themProcess-oriented analysis method is structured, the analysis method has the characteristics of the structure, from the overall point of view to think about the modeling process, such as to create a library book management system, the overall layout design ideas,

project, the organization defines The name of the class, you need to follow certain rules, preferably with the class name as the center, or you can add a uniform prefix or suffix shape into filenames, such as xxx_classname.php, classname_xxx.php, and classname.php, and so on. This example attempts to load the MyClass1 and MyClass2 classes from the myclass1.php and myclass2.php files, respectively Code Snippets Copy the Code code as follows: function __autoload ($classname) {Require_once $c

dependency is the detail depends on the core, When the details change, the core will not be affected, which is a stable dependency. Following this design, we are able to add or change the storage type for the program without affecting the core of the program, as seen in Figure 6:　　 　 Figure 6 　　It is noteworthy here that persistence and application are divided together, because the services in persistence are based on the needs of ap

1, structured analysis methodThe structure method is mainly used to analyze the function of the system, and it is a kind of analytic method that divides the function level directly according to the data stream; The basic feature of structured methods is to use graphical symbols whenever possible when expressing problems, even if non-computer professionals are also easy to understand, design data flow chart

The memory location analysis of static properties and methods in object-oriented PHP, object-oriented static In this paper, we analyze the memory location of static property and method in PHP object-

Js object-oriented design: {} is good or function () {} is good. You have replied and I feel good. I would like to share it with you. I have read many JavaScript projects on the Internet, and the objects used are in the form: For example, jQuery and TinyMCE all have the following shapes: The Code is as follows: Var Dialog ={Int: function (){....},Insert: funct

In-depth analysis of JavaScript Object-Oriented Programming and Object-Oriented Programming Ii. Javascript Object-Oriented Programming: inheritance of Constructors This section describe

Putting these two concepts together is really not neat. But for those who are keen on design, we only need to use it. First, we will explain these two concepts. What Is Oo? Haha, maybe everyone will laugh at me. Oo, who doesn't know? Don't talk to me about encapsulation/Inheritance/polymorphism! These are all so-called features. My question is: what is oo doing? For example, suppose you are a project manager. Now you have a task on hand that you need

Simply put, the structural analysis method is mainly used to analyze the functions of the system, according to the internal logic of the system to decompose the complex system into easy to understand and analyze the subsystem, is a direct data flow based on the function of the analysis method of the hierarchy, The object-orie
