Re: [PHP-DB] Database Design Issue

[Jason Lange]

Yes, songs do span shows. However, the list of songs for each weeks show starts out as a *.asc (same a *.txt) space-separated file. This gets uploaded via a PHP file that formats each row and inserts it into the database. That's why even though I know there will be duplication it appears (to me at least) I'll just have to live with it. I have no guarentee that the songs will appear in the *exact same way* every time either (you really don't want to know why -- I'm getting a migrain just thinking about it). I've attached an example of the incoming files I have to deal with for your reference. Also, I'm just designing the website I will have no part in the everyday maintenance of the website -- except when the maintainer gets stuck.  :) Jason CPT John W. Holmes wrote: From: "Jason Lange" <[EMAIL PROTECTED]> Here's my question. I'm creating a website for a weekly radio show. One of the items I would like to store in the database is the list of songs played in each show (there's normally between 20-25 songs per show), and the songs will be displayed by show. Should I put all of the songs in a single table with a field denoting what show they're from, or should I create a separate table for each weeks show and just request that entire table? I'm looking at this from both a long-term performance and *maintenance* issue. The first question is if songs can span multiple shows? If so, you need 3 tables. One to hold the songs, each song getting a unique id. One table to hold the shows, each show getting a unique id, and finally a third table that relates the two. You'd list the song_id and the show_id that it's used in. Add in a row for each song used in each show. If a song is not shared across shows, then you could go with two tables. A show table where each show gets a unique id and a song table with a column that has a show_id in it relating it to what show it's used in. You'd be better off with the first method, though, because sooner or later down the line there's going to be a song shared, I imagine. :) ---John Holmes...
