How to better design the software architecture is an eternal key topic in the software engineering field. Over the past few decades, the international software engineering community has made great strides in Software Architecture Design
The input signal of the access control system includes:
Landing Lever position sensor: Two position value signal (up/down)
Car entry sensor: Two values (True/false)
Car Gate sensor: Two values (True/false)
The output signal of the access control system includes:
Motor control signal for landing lever: (Up/down)
Traffic light signal: (Red/green)
The passing process of a car is:
The landing lever is in the falling state and the traffic light is red.

The entire software development process is a rather complex process. Instead of simply writing software on the other side by a few design engineers, we need to start from the beginning to the end, including many people and different experts, different specialties and different knowledge are combined to form a complete softwar

To be able to use these principles well and without dogma, my experience is as follows: (I th

Software design method (reproduced)
In order to solve a problem on the platform, the last basic discovery can be implemented after a long time.
During migration to the project, we found that there was an issue that could not be solved by the platform. The problem has not been solved for a long time, and it is even unclear where the problem exists.
At last, my colleagues analyzed the problem step by st

At this time, the stars in the sky are like countless starsThe Treasure of the dark night sky dotted with a few flashes. With this, the software development department on the third floor of Yijing company is brightly lit. The sky
web| design is now a larger scale of the site, involving the department, the number of people is more and more. Naturally, the size of the Web Development group is increasingly complex, resulting in more and more difficult management, in the following article, I will discuss some of the relevant web design concepts.

What is architecture
Software designers who have high technical skills and rich experience need to design the architecture of the software system, that is to say, we need to design how the system's components are divided, how components interact, and how logical, physical, and important decisions are made in the system
Write the outline design instructions correctly
Before the need is clear, ready to start coding, to do the outline design, and the detailed design may be most of the company did not do, and do most of it and coding synchronization, or after coding. Therefore, for most companies, the profile design document is the only

Overview
Software design is the most important part of converting requirements into software systems. The advantages and disadvantages of system design fundamentally determine the quality of software systems.
This article mainly describes five core components of
