Real software developers will use this method to predict the future

There are always fox friends asking ： Tell me directly , What is object-oriented , Can quickly complete a function ？

The most direct way in the world , Can put my way of thinking , Instead of teaching specific knowledge points to others , Probably only conscious transmission .

in fact , There is no conscious transmission yet , So there is no separate direct , I can tell you , What is object-oriented ？ Because using object-oriented thinking to develop software , It is a systematic thinking , Instead of thinking in isolation . To complete a function , Need knowledge points of several classes , And how .

I have seen some code of fox friends , Each function starts with creating a database connection , Various maintenance states , Various IF, A thousand lines at a time .

Is this code valuable ？

Yes ！ Commercially valuable , Technology if every function is such code , Will create more and more technical debt .

It will eventually lead to understanding a business flow , It's a very painful thing , Too many IF, Too much code that has nothing to do with business flow . If it's new , There is no way to take over such code .

Using object-oriented thinking , Yes, it can be predicted that the functions may be increased in the future , Will change , In programming, you can reserve positions , Provide the best scalability .

So how to reduce this technology debt ？

Study , communication , Many people have written programs for more than ten years , I thought I had mastered the truth of writing software , On the contrary , We should always improve ourselves , Kung Fu is beyond poetry , Master object-oriented , It's easier to write programs , After you have the specifications , Newcomers can develop according to this specification , The team was set up .
If you have new people , I don't know , Cats can teach , Can help you take .

Some people also asked whether the original software could be integrated into the Qiyou three-tier development framework （ Cat frame ）, The answer is yes , Later I will write more about how to integrate .

Is it a good idea to put the code in the database

Now Qiyou has a three-tier development framework （ Cat frame ） It's through BS CS APP Applet official account payment Object storage SMS and other functions .

Recorded hundreds of G In the video , No matter where you want to get started , Cat cat courses can let you enter the real modern software development mode .

Some people like to put code in a database , Then dynamic execution and so on , Personally, I don't like it .
Internet applications , A large part of the bottleneck is brought about by the database , So the first step of optimization is to separate read and write , So how about putting the code in the database ？

Learning mentality

Object oriented thinking includes process oriented thinking , A level higher than process oriented thinking , Please don't fall into point-to-point comparison , It's easy to get into trouble .

We can learn a knowledge system , The content of its course , There is a certain order . Namely ——

The content of the next lesson ,

Must be heard after 、 On the basis of mastering the previous section ,

To understand .

therefore , Half a barrel of water is the easiest ——

Want to get... Quickly , But not enough .

Want to learn quickly , But it's impossible .

This kind of phenomenon , I often see it in my life , It's a midlife crisis , Or unemployment , Looking for a sideline to make money . But all of a sudden , others 「 Relaxed 」 What can be done , I don't seem to know anything .

therefore , Buy all kinds of classes , Learn various methods , Add various communities , Trying to quickly make up for this lack .

But the result is , No dice .

Because money can only buy methods 、 skill 、 knowledge , These belong to know .

But between knowing and doing , It's one hundred and eight thousand miles apart .

It takes ability to do .
And ability , It takes practice .
Deliberate practice , It takes a lot of time , Boring repetition .
Obviously , It can't be done quickly .

《 Treat time as a friend 》 There is an example

“ Theoretically speaking , How long does it take a person to accumulate fat , I want to use up the fat , It will take about the same time .” therefore , If a person 25 I began to gain weight at the age of ,35 When I came to the gym at the age of 40 Kilogram fat , Then ask the coach to help him in 3 Lose fat within months 、 Return to standard figure , It's just a dream . Of course , Work harder , You can put 10 The year is shortened to 5 year , Even twoorthree years , But this time must be much longer than those who plan to achieve it overnight .

This explains why so many people always fantasize about something “ Fast track ” Methods ？
Because I lay flat for too long , Suddenly I got a big test , Find that there is not enough time , The deadline is coming , So we can only hope “ Fast track ” The existence of methods .
We can also make a surprise attack on the previous exam , Now in the real world , No, 60 branch , Only can or can not be .

《 Treat time as a friend 》

The book also gives some solutions ——

therefore , The right strategy should be ： Find ways to predict in advance what skills you need to master , Make sure they are skills that you can really master through practice , And then make a long-term plan , Steady implementation bit by bit .

This strategy , For everyone , Every field , Every profession .

And the most important point , Learn from the best people around you , It could be your boss , friend , Relative , Master at least one computer language to improve work efficiency .
