MySQL is a widely-used open-source relational database management system (RDBMS). It is known for its reliability, robustness, and ease of use. MySQL is based on the SQL (Structured Query Language) language, which manages and manipulates relational data stored in tables.
MySQL supports various data types, including numbers, strings, and dates, and it allows for the creation of complex data structures such as tables, views, and stored procedures. It also provides a wide range of built-in functions for data manipulation, such as mathematical functions, string manipulation, and date functions.
MySQL uses a client-server architecture, with the MySQL server handling data storage and retrieval and client programs sending SQL statements to the server to be executed. The server can be run on various platforms, including Windows, Linux, and macOS.
MySQL also supports data replication, which allows for data to be automatically copied from a master server to one or more slave servers. This helps ensure high availability and allows for load balancing across multiple servers.
MySQL is commonly used in web-based applications, particularly those built using the LAMP (Linux, Apache, MySQL, and PHP) stack. It is also used in many other applications, such as data warehousing, e-commerce, and logging. It is known for its high performance, scalability, and robustness.
