Quick Question Regarding DB versus Objects

If you have a diabloish party setup, what would you prefer, saving the party in a db or any other static data, or make an object(maybe i got it all wrong here since most, if not all, objects have a visual reprensentation) which gets a handle name and like 5 slots, in which you state the handles of the members in the party. Maybe simply adding a id variable to the members would sufice, but how would i get an unique id for each party?

Strictly off topic: anyone got their hands on bioshock? That is one fun game im telling ya, but im a bit disapointed on the horror side though, and all the enemies rabble so much that you have hard time discerning what they say. But otherwise the atmospehere is really good. Allows for some pretty unique kills too =)
