The MusicBrainz Database is built on the PostgreSQL relational database engine and contains all of MusicBrainz' music metadata. This data includes information about [[Artist|artists]], [[Release Group|release groups]], [[Release|releases]], [[Recording|recordings]], [[Work|works]], and [[Label|labels]], as well as the many [[Relationships|relationships]] between them. The database also contains a full history of all the changes that the MusicBrainz community has made to the data. |

The MusicBrainz database stores all the data of the MusicBrainz '''music metadata catalogue'''. This data includes all the data about [[Artist|Artists]], [[Release|Releases]], [[Track|Tracks]], [[Advanced Relationships|AdvancedRelationships]] between them, but also the MusicBrainz users ([[Editor|editors]]) and the changes they entered into the database ([[Edit Type|edits]]). |
