Don ' t Repeat yourself (DRY)DRY is one of the simplest laws and is the easiest to understand. But it can also be the hardest to apply (because to do so, we need to do a lot of work on generic design, which is not an easy task). It means that when we find some similar code in two or more places, we need to abstract their generality into a unique new method, and change the existing code so that they can invo
Finally, I have read Mr. Zhang Yi's book "Essentials and patterns of software design", and I am deeply impressed by his understanding and explanation of software design, I have a new understanding of the software
maintenance personnel often find problems in the system, but do not dare to modify it easily, especially the underlying part of the system. The reason is very simple: the system has been running well and there are no errors, and because there is no complete documentation, there is a worry that new problems will occur after the changes. This concern reflects the fact that programmers have doubts about whether the current
Object-oriented design is mainly about the concept of design, software architecture, system design, detailed design, application design mode, user interface design and

This article introduces some of the principles in software design, which are learned after long-term experience. Every programmer should understand them. I believe it will be of great help to everyone in the process of software design.
Don't repeat yourself (dry)Dry is the simplest rule and the easiest to understand.
, it is also conducive to user improvement to achieve a real win-win situation.Requirement analysis refers to the process of turning user requirements into software requirements. These two processes are complementary to requirement research, further research is required during the analysis process. Clarify the business model, business logic, and operation process.The architecture design and detailed
designers (perhaps the company is not willing to pay the price), so I define the general web designer as coder Designer.
But how can we make reasonable arrangements for those who do not have the ability to be outstanding and to do a stable project? In practical applications, we often use the definition of a unified design method (whether dominant or not dominant), or more specifically using such methods as templates, JS, SSI output, for a developmen

A good start is half the success
The initial architecture design determines the survival of software products. "A good start is half the success ".
The initial architecture design is also the most difficult. We need to investigate the situation and technical characteristics of similar products and learn about the theoretical support and technical platform suppor
time to create an object.
First, let's look at the features of objects. The types that represent the abstract meanings, such as interfaces and abstract classes, cannot create object instances, which means that the objects we want to create are all related to object types. That is to say, the creation of objects involves implementation details in the design, which leads to an enhanced coupling between the creator and the specific creation. For example
The vicissitudes of software R D over the past decade and the painful experience of first-time bankruptcy have given me a deeper understanding of software product development. When the New Year is approaching, I will write a speech to share with you.
