Is mysql a relational database?

MySQL is a relational database management system. A relational database stores data in different tables instead of putting all the 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 edition and commercial edition. Due to its small size, fast speed, low total cost of ownership, and especially its open source nature, MySQL is generally chosen as the website database for the development of small and medium-sized websites.

4. Support SQL, which can be used for complex queries.

Disadvantages of relational databases

1. The huge price paid for maintaining consistency is poor read and write performance;

2. Fixed table structure;

3. High concurrent reading and writing requirements;

4. Highly efficient reading and writing of massive data;
