The computer software industry is a young industry born in 1950. It has only a history of more than 50 years. In contrast, architectural design can be traced back to the Egyptian pyramid era thousands of years ago, or even earlier. Therefore, computer software designers can learn a lot from architects. There are obvious similarities between the

changed. Obviously, such a decision must be the most important decision on the success or failure of system design and must be carefully studied and investigated.
The history of Computer Software began in 1950s, and its history was very short. In contrast, construction engineering started from the Stone Age, and humans have accumulated a lot of experience and lessons in architectural
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

I recently attended a lecture called a software architecture master. I had doubts when I saw the lecture. I listened to the lecture for five minutes and verified this question, after the lecture, I heard comments from my colleagues, which strengthened my judgment. However, I only listened to the audience for five minutes, but it was not easy to comment. I just felt that the metaphor used in the speech almost covered up engineering pract
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

constantly changing, it should be understood that "demand change" is a normal.There are many reasons why demand changes, such as:(1) Because some preconditions are not fulfilled, they are implemented according to the "compromise" scheme, but if these preconditions are satisfied at a certain point in time, they cause the change of demand.(2) There is no need to go through the approval process before a background operation, but because a customer's internal process changes, the need to go through
classes, and using multiple specialized interfaces is better than using a single total interface.For example, we have different ways of using computers, such as: writing, communication, watching movies, playing games, surfing the internet, programming, computing, data, etc., if we declare these functions in the computer's pumping class, then, our netbook, PC, Server, notebook implementation class are to achieve all of these interfaces, It's too complicated. Therefore, we can isolate these funct

around concurrency can cause the system to become essentially serial, limiting the ability to scale. Concurrent programming is not difficult, and there are some simple principles that can help when building a scalable system.If you do need to hold locks (such as local objects, database objects, etc.), try to hold them as short as possible.Try to reduce contention for shared resources and, as far as possible, compete to avoid critical processing paths
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.

My friend asked me, what can I do with my computer? I can do anything you think. In fact, I am quite ignorant of this.

netbook, PC, server, and notebook implementation class will implement all these interfaces, this is too complicated. Therefore, we can isolate these functional interfaces, such as work learning interfaces, programming and development interfaces, online entertainment interfaces, and computing and data service interfaces, computers with different functions can selectively inherit these interfaces.
This principle can improve our software development by

The structure he creates is far more stable than a simple top-down or bottom-up structure.

In this way, they can use knowledge of similar problems to solve some subproblems,
In addition, abstraction helps them make inferences and judgments.
When building a system, we should select the architecture that best meets the current needs and implement functions under the framework of this architecture.
