database
Within the MariaDB data directory, each database is represented by a separate directory. The InnoDB system tablespace, which can hold table data from multiple databases within a MariaDB instance, is kept in its data files that reside outside the individual database directories. When file-per-table mode is enabled, the .ibd files representing individual InnoDB tables are stored inside the database directories.
For long-time MariaDB users, a database is a familiar notion. Users coming from an Oracle Database background will find that the MariaDB meaning of a database is closer to what Oracle Database calls a schema.
