An Introductory Guide to SQL Database Systems: Understanding MySQL(mysql英文)
MySQL is a popular open-source Structured Query Language (SQL) database system that helps store and manage data. It is widely used by private and public organizations to store and retrieve data. This article provides an introduction to the basics of MySQL and how it can be used to build robust, reliable and secure database systems.
First, it is important to understand the terminology used when talking about MySQL. SQL is the language used to communicate with the database and retrieve data. A database is an organized collection of related data. MySQL is a type of relational database, meaning it stores data in separate tables that are linked together by relationships.
A few of the most commonly-used commands in SQL, like CREATE or SELECT, can be used to create or view the data stored in a MySQL database. The most common way of accessing data from a MySQL database is via a query. Often, queries are written in the Structured Query Language (SQL), which is a standardized language for data retrieval.
The vast majority of web applications or websites make use of MySQL databases to store and retrieve data. This is because MySQL databases are easy to set up and maintain, and are very cost-effective.
To get started with MySQL, you will need to download and install MySQL on your server or local computer. Once installed, you’ll need to create a database. This can be done with the command line tool or by using a graphical user interface like phpMyAdmin.
Once your database has been created, you can start creating tables and entering data. This can be done through the command line or through the MySQL command line tool. To access the data stored in your tables, you will need to write SQL queries.
Overall, MySQL is a powerful and reliable database system. It provides a simple way to store and retrieve data, and is easy to set up and maintain. With the right commands and queries, you can easily build complex and secure web applications.
If you are interested in learning more about MySQL and how to use it to develop robust databases, there are numerous resources available for you. There are a variety of tutorials and guides available online, as well as books and courses specifically devoted to learning the language. With a little practice and advice, you can master MySQL and start building productive and secure database systems.
