Statement: This series of blog reference "Big Talk design mode", author Geoscience. It is generally considered that code that complies with the following six principles is easily extensible and reusable: the six principles of any object-oriented language should be adhered to, in order to make your code easy to expand high-consumption as far as possible to meet th

With the C # language foundation, we still need to learn the design pattern principle before learning the design pattern. This is the premise of the design pattern and is the criterion for us to judge whether the design is reasonable. So in this blog, I will first learn and

database, in the file system in the C + + language after the processing is completed, the final storage is appended to the table. 　　 This is the experience of telecom billing system design. (3) If a table is found to have too many records, such as more than 10 million, the table is split horizontally. Horizontal segmentation is done by dividing the table's records horizontally into two tables with a value

Seven Principles of Software Design The general principles of design patterns are as follows: 1.Open-closed principle ):A software entity should be responsible for extended development and should be closed for modifications. when designing another module, the module should be extended without being modified. in other

General principles of design pattern adherence:1. Open-Close principle (open-closed Principle, OCP): a software entity should be developed for expansion and closed for modifications. The point is that when designing a module, the module should be extended without being modified. In other words, It should be possible to change the behavior of the module without having to modify the source code, and to extend

I recently encountered a problem with the design principles of OOD during the written examination. From http://www.cnblogs.com/xwang/archive/2009/01/13/1374652.html Five Principles of OOD: (1): SRP, single responsibility principle (only Buddha should assume the responsibility to publish xuanmiao secrets ...) A class should have only one reason for change. Because

Database Design Principles 1. The relationship between the original document and the object can be one-to-one, one-to-many, and many-to-many. In general, they are a one-to-one relationship: an original document corresponds to only one entity. In special circumstances, they may be one-to-many or many-to-one relationships, that is, an original document corresponds to multiple entities, or multiple original do

In the object-oriented Master Robert C. in Martin's Agile Software Development: Principles, patterns and practices, only the OCP, LSP, SRP, dip, and ISP mentioned above are listed as the design principles of Ood. Indeed, these principles are the cornerstone

know as little as possible about other objects.Basic idea: reduce coupling.g: the principle of synthetic multiplexingInstead of using inheritance, it is preferable to use a combination rather than an inheritance principle, which is to use the composition/aggregation method first.Basic idea: In taking advantage of the object's lowest point, the combination is preferred, not the inheritance, because any changes to the parent class can directly affect the behavior of the subclass.eg. To pack an el

Several Python Function Method Design Principles summarized This article mainly introduces several Python function method design principles, this article explains how to do one thing for each function, keep it simple, keep it short, input and use parameters, and output and use return statements. For more information, s

principleDefinition: The client should not rely on interfaces it does not need, and the dependency of one class on another should be based on the smallest interface.The problem is that class A relies on class B through interface I, Class C relies on class D through interface I, and if interface I is not the smallest interface for Class A and Class B, then Class B and Class D must implement methods that they do not need.Solution: Split the bloated int

the necessary guidance and "reward" feedback for their exploration and learning behavior.PrototypeRegardless of style, the interface form depends on the actual function. Good design solutions are inseparable from pre-production planning, especially through sketches or wireframe prototypes. Identify the core use case requirements, use prototypes to continually try and validate, and lay a solid foundation fo
