object oriented database software

Notes on javaScript object-oriented and prototype, javascript object-oriented JavaScript is a special language. ECMAScript does not have the class concept and is different from other object-oriented languages, its objects are also

software development process, not all code is written in one file. You can imagine that a small program has about 10000 lines of code written in one file, are you still doing this? The correct method should be to split the program into one module. For example, you can put executable files in common bin directories and configuration files in conf directories.Store data in the db directory, log files in the log directory, libraries in the lib directory

only one change point (every class shocould attempt to make sure that it has only one reason to this, the death of each badly designed piece of software .) What remains unchanged in the software is changes. Poor design will cause the software to crash in changes, but good software can be easily changed. Each type

Object-oriented python: object-oriented python I. Classes and objects 1. What is a class?Class.Object refers to an instance of a specific abstract class. Does the above statement seem a bit cloudified. Yes, professional explanations are hard to understand. This is an expert. In fact, for a simple example, you can under

the concept of object-oriented, we know that all objects are depicted through classes, but this is not the case. Not all classes are used to depict objects. If a class does not contain enough information to depict a specific object, such classes are abstract classes. Abstract classes are often used to represent the abstract concepts we have come up with in the a

Object-oriented principles:Liskov substitution principle (LSP) depends on the Dependency inversion principle (DIP) interface isolation principle (ISP) composite/aggregate Reuse Principle, CARP) principle of minimum knowledge (principle of least knowledge, PLK, also known as the dimit Law) single responsibility principle (single responsibility principal, SRP) the principle of openness and closure is idealist

Three main features of Java object-oriented, java object-orientedJava object-oriented features: encapsulation, inheritance, and Polymorphism Encapsulation and inheritance are almost always prepared for polymorphism.I. Encapsulation First, attributes can describe the features

our intuition. Object-oriented technology is to use the objects in the software to simulate objects in reality. If a dog is not a cat, it cannot be inherited from a cat. However, in actual software development, it is quickly discovered that in some cases, even if Class A does "is a" Class B, inheritance cannot be used

The factory mode and constructor mode are introduced in javaScript object-oriented design and Javascript object-oriented design, as well as their advantages and disadvantages, today, we will continue to explain the prototype mode. Each function we create has a prototype attribute, which is an
