But if a band can have songs in many albums and an album can have songs
from multiple bands, it's a many-to-many relationship, NOT one-to-many. Short of the full track design suggested by
PFC,you'd normally
implement a many-to-many table as follows:
CREATE TABLE bands_on_album (
band_id integer REFERENCES band (id),
album_id integer REFERENCES albums (id),
PRIMARY KEY (band_id, album_id)
)
This of course precludes the same band being listed twice in a given
album. If you do need that info, then you're really asking for "tracks".
