Structure explanation

The most important table is the Songs table, which is the starting point for all song-specific info. To allow rapid requests, most of the information is present in the table itself, e.g. the Artist name is spelled out. The link between table Songs and other tables like Artists, Albums, ... happens with intermediary tables, e.g. ArtistsSongs. This allows us to assign multiple songs to one artist, AND multiple artists to one song.

The database contains custom events, called "triggers", that are executed when e.g. an artist is assigned to a track. For that example, the trigger will automatically increment the Artists table's Tracks counter field.
