Question

I want to make a music playing website where users can save playlists of songs to be regenerated later. I’m kind of a newbie to sql, but it seems like databases are meant to hold fixed-length variables, whereas a user-generated playlist would be an arbitrary length. There are a couple ways I’ve thought of to handle this:

• Separate tables (maybe another table for each playlist? )
• XML

I feel like there’s an easy third way I’m missing. I’m doing this in php, but if there’s a super easy way using django I’d also be interested.

Answer 1

2 tables:

1. Playlists. Fields: id | title | owner_id (reference to user.id)
2. Songs. Fields: id | title | length | playlist_id (reference to playlist.id)
