MySQL is a relational database management system. A relational database stores data in different tables instead of putting all data in one large warehouse, which increases speed and flexibility.
The SQL language used by MySQL is the most commonly used standardized language for accessing databases. MySQL software adopts a dual licensing policy and is divided into community version and commercial version. Due to its small size, fast speed, low total cost of ownership, and especially the characteristics of open source, MySQL is generally chosen as the website database for the development of small and medium-sized websites.
Due to the excellent performance of its community version, it can form a good development environment with PHP and Apache.
At present, the database is the basic component for data storage in most systems. The efficiency of the database has a vital impact on the stability and efficiency of the system; in order to have a better user experience, the optimization of the database is extremely important. So from what aspects should we optimize our database? Let us discuss and learn together in the course "Boolean Education Yan 18 MySQL Optimization Video Tutorial"!
