What are the information_schema tables I see when viewing my database?

The answer could probably best be answered by MySQL.com - INFORMATION_SCHEMA provides access to database metadata. Metadata is data about the data, such as the name of a database or table, the data type of a column, or access privileges. Other terms that sometimes are used for this information are data dictionary and system catalog. INFORMATION_SCHEMA is the information database, the place that stores information about all the other databases that the MySQL server maintains. Inside INFORMATION_SCHEMA there are several read-only tables. They are actually views, not base tables, so there are no files associated with them. Therefore, you can safely ignore these tables. They are read-only so they can't be edited or removed. For more information on this, please visit http://dev.mysql.com/doc/refman/5.0/en/information-schema.html | |
