MySQL is one of the world’s most popular relational database management systems (RDBMS). It is used to store, organize, and manage data for websites, web applications, content management systems, and business applications.
Many popular platforms, including WordPress, Joomla, Drupal, Magento, and PrestaShop, rely on MySQL databases to store content, user accounts, settings, orders, and other important information.
Table of Contents
How Does MySQL Work?
MySQL stores information in tables consisting of rows and columns.
For example, an online store may have separate tables for:
- Customers
- Products
- Orders
- Payments
- Categories
These tables can be connected through relationships, allowing applications to efficiently retrieve and process data.
MySQL uses SQL (Structured Query Language) to communicate with databases. SQL commands allow users and applications to:
- Create databases and tables
- Insert new data
- Modify existing records
- Delete information
- Search and filter data
