MySQL
The storage structure of
MySQL consists of several layers, primarily the storage engine layer and the file system layer.
MySQL supports multiple storage engines, with InnoDB being the most commonly used, which provides features like transactions, foreign keys, and row-level locking. Data is stored in files on disk, with each table typically represented by one or more files, depending on the storage engine. Additionally,
MySQL uses a data dictionary to manage metadata about the tables and their structures.
