So what do you need to know in the process of adjustment? Among them, the most important are mentality, skills and technology.
In the process of learning computer training, we need to master more problems.
I. Mentality In the practice of any project, the issue of mentality is the most important, followed by technical issues.
Why is mentality the most important issue? Because for the old functional modules over 10 years old, the most complicated functional module is actually business logic, not technical implementation.
Therefore, for the reconstruction of the old system, it is necessary to sort out the business logic accumulated on a large scale in the module, which in itself provides invisible pressure for the reconstruction.
Coupled with the core business module, the lack of business logic will lead to a decrease in online income, which will eventually lead to a lot of time for programmers.
This series of backgrounds makes the psychological pressure in the process of reconstruction even greater.
The best way to reconstruct a project is to sort out all the business logic carefully, and then draw a picture with your mind, so that you can clearly understand all the business logic in the past.
Clear business logic is very helpful for subsequent system redesign and coding, and it is also a decisive part of the role.
Second, the experience and skills of skill reconstruction are far more important than technical strength, because experience can reduce a lot of unnecessary troubles.
Before speaking my mind, I want to ask a question: If you encounter a problem in the process of refactoring, it will make the project better, but if you don't solve it, it won't have much impact. What will you do? In this case, Shandong Beida Jade Bird suggested that it is best not to do it, and it is best not to do it without affecting the reconstruction goal. This is not laziness, but you never know how big the pit will be waiting for you.
Third, technology is the last step, but not the most important one. At least in the process of reconstruction, I can basically complete 60% of the work due to my lack of mentality or technology.
The reconstruction technology in my project can be completed in less than 10% time.
Refactoring technology is actually more about using design patterns and presenting complex business logic with concise codes.
In short, it uses design patterns to carry complex business logic and make the code as concise as possible.
Refactoring needs more tests, mainly in-depth understanding of business and further application of abstract thinking.
If the business is deep and abstract, you can choose Shandong Beida Jade Bird for learning and design mode.
If it is the opposite, there is no way.
