Facebook app database issue: Store my own User ID or just use Facebook UID?

Question

Hi there,

I want to create a Facebook app that can operates inside IFrame / FB connect. I have to store some user information inside my database, but I still can't decide whether to use Facebook UID as the primary key or to create my own user ID (and have the Facebook UID as a regular column). Which approach is commonly used and why?

Thanks ! Andree

Answer 1

The Facebook UID are also unique, as far as I am concerned, i always use the Facebook UIDs. Although that shouldn't a problem if you create your own ID but that would be an extra overhead.
