UNE BASE DE DONNEES

Définition

Une base de données est une entité dans laquelle il est possible de stocker des données de façon structurée et avec le moins de redondance possible. Ces données doivent pouvoir être utilisées par des programmes, par des utilisateurs différents. Ainsi, la notion de base de données est généralement couplée à celle de réseau, afin de pouvoir mettre en commun ces informations, d’où le nom de base. On parle généralement de système d’information pour désigner toute la structure regroupant les moyens mis en place pour pouvoir partager des données.

l’utilité d’une base de données ?

Une base de données permet de mettre des informations à disposition d’utilisateurs pour qu’ils puissent les consulter, les modifier, les mettre à jour…
Voici quelques exemples courants d’utilisation.
Une base de données peut être locale, c’est-à-dire utilisable sur une machine par un utilisateur, ou bien répartie, c’est-à-dire que les informations sont stockées sur des machines distantes et accessibles par réseau.
L’avantage majeur de l’utilisation de bases de données est la possibilité de pouvoir être accédées par plusieurs utilisateurs simultanément.
