advantages of the pad chart: (of course, these are all compared, and these three figures can be compared and learned)
1. It must be structured.
2. Clear
3. The program structure is easy to understand and easy to remember
4. It is easy to convert a pad chart into a program in advanced language.
5. You can describe the data structure.
6. Supports Top-Down refinement process
Of course, we can also use the table tool such as table determination and pseudo-code to implement these designs. Here we w

The relationship between software and human beings is the core issue that architects must face. It is also a problem that has occurred since the software entered the stage of history. Like this, the relationship between architecture and human beings has been the core issue that architects must face since building. British Prime Minister Church
into the calling class? You may declare it as a member, and you can pass the function arguments through the constructor. But IOC allows you to generate the actual configured class through a configuration file, a configuration file read by the service Container.

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.

EIT is a basic Structure, a Concept (Concept); we call it "EIT Form )".
Likewise, a circle or an ellipse is a basic geometric structure. It is called the geometric structure of amicide.

Control as the most basic elements of the Organization interface, I believe we will not be unfamiliar, today want to talk about this humble topic. The article from the reality of the control transition to the software interface, and then use the three input method of the control as a practical case explanation, full-text dry, to receive!First, the real-world control"After the bell rang, Xiao Ming immediately rushed home, home after a change of shoes i
, if we put the dough, shape, heat, and cooling in the same machine, then this machine can only make one kind of cake. However, if we divide these functions into different machines, some machines and faces, and some machine stereotypes, we can think of them. For example, a new cake can be made when the surface is first joined, heated, finalized, and cooled. You can even make a variety of things that are not cakes. Then we want to cope with the changes. We want to add the function of adding eggs
In fact, what is the use of financial software? I think it gives people a quick impression on how to use their existing wealth, how to allocate and design new financial solutions.
Generally, we don't need complicated financial management tools. We need to use this mathematical tool only for large items. For example, when buying a house or calculating income tax,
This study is mainly in the design process of the inspiration method and design practice of some experience.For detailed programming work, it is normal to expect deterministic behavior because software design is nondeterministic. Flexible and skillful use of a set of effective revelation methods (heuristics). becomes t
