guest CRUD?

[eluser]Corbee[/eluser]
Hi,

I was planning to create a CRUD part in a registration form, wherein people can add their car profiles countless times.

What's the best way to do it? Session or database?

if session,

how do I display a tabular list to the user, then allow him to add and delete according to his desire?

if it is database

how do I remove it once it is done, or if the time expires?

Thanks
