Database structure refresher

[phppup]

I'm a bit rusty in the database department and would appreciate a quick review and any pointers.

I'm planning to set up a database for a DJ (that colloquially spins records).

The DJ does work with multiple organizations. Each organization sponsors several events per year. Each event has a separate 'playlist' depending on the audience.

From this skeletal overview, I'm thinking that I should establish a primary key/foreign key relationship (to avoid future complication?).

I'm certain that referencing an auto increment ID as the foreign key associated with the 180 character organization name will save valuable disk space, but how do I reference it when I'm adding a new event that the XYZ org is sponsoring?

Any other refresher pointers appreciated.

Your form for entering new events would contain a dropdown listing organisations for the user to choose. The value of each dropdown option would br the organisation's id. This id is posted (with the other event data) for insertion into the event resord.
