beth, that's a interesting way you mention. (Sounds like a question of storage, not execution time handling.) I think what Beth is suggesting deals with data normalization techniques- where you break down everything into the smallest most simple tables possible(?). It makes it so the data is not duplicated, it makes your sql queries a little more complicated (a lot), but the whole thing works better. Basically your friend people table: person_id name 1 joe 2 leo 3 jimmy And your friend table: person_a_id person_b_id 1 2 1 3 This shows that joe is friends with leo and jimmy- but leo and jimmy are not friends.
