    <p>Each table in the information_schema database is a TEMPORARY MEMORY TABLE</p> <p>For example, notice <code>information_schema.tables</code></p> <pre><code>mysql&gt; show create table information_schema.tables\G *************************** 1. row *************************** Table: TABLES Create Table: CREATE TEMPORARY TABLE `TABLES` ( `TABLE_CATALOG` varchar(512) NOT NULL DEFAULT '', `TABLE_SCHEMA` varchar(64) NOT NULL DEFAULT '', `TABLE_NAME` varchar(64) NOT NULL DEFAULT '', `TABLE_TYPE` varchar(64) NOT NULL DEFAULT '', `ENGINE` varchar(64) DEFAULT NULL, `VERSION` bigint(21) unsigned DEFAULT NULL, `ROW_FORMAT` varchar(10) DEFAULT NULL, `TABLE_ROWS` bigint(21) unsigned DEFAULT NULL, `AVG_ROW_LENGTH` bigint(21) unsigned DEFAULT NULL, `DATA_LENGTH` bigint(21) unsigned DEFAULT NULL, `MAX_DATA_LENGTH` bigint(21) unsigned DEFAULT NULL, `INDEX_LENGTH` bigint(21) unsigned DEFAULT NULL, `DATA_FREE` bigint(21) unsigned DEFAULT NULL, `AUTO_INCREMENT` bigint(21) unsigned DEFAULT NULL, `CREATE_TIME` datetime DEFAULT NULL, `UPDATE_TIME` datetime DEFAULT NULL, `CHECK_TIME` datetime DEFAULT NULL, `TABLE_COLLATION` varchar(32) DEFAULT NULL, `CHECKSUM` bigint(21) unsigned DEFAULT NULL, `CREATE_OPTIONS` varchar(255) DEFAULT NULL, `TABLE_COMMENT` varchar(2048) NOT NULL DEFAULT '' ) ENGINE=MEMORY DEFAULT CHARSET=utf8 1 row in set (0.00 sec) mysql&gt; </code></pre> <p>Also, notice that whenever you run mysqldump using --all-databases, <code>information_schema</code> NEVER SHOWS UP.</p> <p>The sole purposed of the information_schema database is to store metadata of the physical files and logical description of tables in the database. Whenever you run <code>service mysql start</code>, mysqld will create all the information_schema tables. Afterwards, mysqld populates these temporary memory tables with information concerning the physical files.</p> <p>In terms of reloading a databases, please let mysqld handle the information_schema database.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
