Juste une petite question suite à ma première et fraîche install de Wampserver. C'est normal les 4 petites bases de données que je vois sous phpMyAdmin ? Leurs noms : - information_schema - mysql - phpmyadmin - test Ca vient d'où ? C'est normal ? Puis les supprimer ?
source : site mysql 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 you will not actually see any file associated with them.
