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 [[Advanced 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 various [[Artist|artists]], [[Release|releases]], and [[Track|tracks]] can be linked together with [[Advanced Relationships|relationships]] that enrich the depth of collectible data. For example, relationships can provide information about web resources (e.g. Wikipedia pages, download locations, review pages, etc), or they can indicate instrument/vocal performances on a piece of music. These relationships allow MusicBrainz to capture most of the data contained in the liner notes of an Audio CD.
