What you need to learn for back-end development is: 1. Related knowledge of programming languages, such as Java, PHP language, etc.; 2. Related knowledge of databases; 3. Related knowledge of frameworks commonly used for development; 4. , Relevant knowledge of http protocol.
The main content of back-end development is as follows: first, the learning of programming languages such as Java, etc., and then the learning of databases and commonly used development tools. Framework learning, in addition to learning http protocol, etc.
There are many beginners who want to learn back-end development technology, but don’t know how to learn. Next, I will share with you how to learn the backend in the article, which has a certain reference effect and I hope it will be helpful to everyone.
For a back-end beginner, first you need to know some knowledge about front-end technology, such as html, css, and js. Because when working on the backend, we often have to take into account the optimization of the front-end
Programming language learning
For beginners, getting started with Java is a good choice . It is an object-oriented programming language. In addition to learning its basic syntax, we also need to understand features such as encapsulation, inheritance, and polymorphism, because the technologies in the framework we learn later all depend on it. Therefore, you must lay a good foundation when learning Java. The following are books and videos recommended for everyone to learn Java
Book recommendations: "Java Core Technology", "Java Programming Thoughts", "Design Patterns"
Video recommendation:Java tutorial
Database
You must not do without back-end development Database support, which is a library used to save data information. We can think of the database as a data table in Excel. Each table in the database is similar to a sheet in Excel, db is each Excel file, and sql statements are instructions that can help us operate the data inside. For database learning, I think the mysql database is the most suitable for getting started. Recommended books and video tutorials are as follows

Framework learning
The framework has improved a large number of method encapsulations for our development, and we can call it directly to solve problems and greatly improve development efficiency. At the same time, the framework can help us write code in layers to facilitate later maintenance. In addition, it can also do some security protection to protect our data security
Recommended books: "Mastering SpringMVC (Fourth Edition)"

http protocol
The browser and the server interact through the http protocol, which actually means transmitting information between each other. A string in a specific format. Information such as get parameters, post parameters, url, and cookies are actually included in this string. Therefore, the http protocol is an important existence, and it is also an essential point for us to learn back-end development
Book recommendation: "http authoritative guide"
VideoRecommendation:http tutorial
Summary: After learning the above knowledge, you can do simple back-end development knowledge, but if you still find development difficult, then Requires a little more development experience. Continuously improve your knowledge and skills through the accumulation of projects
