what happens when deleting an album with songs? what happens when deleting a band with songs? what happens when deleting an artist with an album?

In the first case that is the only one that has been programmed so far, to delete an album with songs, the relation is has_many: songs, dependency:: nullify which will allow to erase the album and leave the songs in the database without album assigned. Actually, I defined the album param as optional for songs. Eventually, a song can never have an album (e.g .: singles). If I made the decisions, I would leave the children alive and orphans in the three cases (it will also require a depuration task in the future). Anyway, this is clearly a business rule that must be defined by the product owner, then we write the programs so that they work accordingly.
