Analysis of the data object ing mode in php design mode, analysis of design mode There are many different design modes in php. Here we will introduce you to an uncommon data ing mode. I hope this article will help you. The data in

Before studying the design patterns of object-oriented design, I had a vague understanding of Java interfaces and Java Abstract classes. When I first learned the Java language, it was hard to understand why the concept of interfaces was required. Although multi-inheritance can be implemented, there is only a method nam

describes how to implement the "open-closed" principle in the object-oriented design. (1) interface-oriented programmingInterface-oriented programming has the following advantages:A. reduce coupling between various parts of the program and make it possible to swap program m

can be built by sticking design patterns, how the interfaces of these patterns, whether the existing models are sufficient, and what types of models should be used. 3,How can we systematically develop applications using the design mode.

direction as much as possible, that is, the top-level classes should share work in a unified manner according to the design. (13) do not create all-powerful classes/objects in your system. Be especially careful about the classes whose names include Driver, Manager, System, and Susystem. Plan an interface instead of implementing an interface.(14) be careful with classes that define a large number of access methods in public interfaces. A large number

Object-oriented design principlesBorn to support maintainability multiplexing, these principles are embedded in many design patterns, which are the guiding principles that are summarized in many design scenarios, and understand Object
