moving a db

Hello,
I need to copy a db from one computer with its own instance of SQL server to another computer with its own instance of SQL server. This is an very big db, and I would like to get it over as quickly as possible. I’ve tried DTS before, and that takes forever, and I always get FK constraint violations. I just noticed something about sp_detach_db and sp_attach_db. This seems much quicker and easier. Am I correct in assuming this? If so, how would I do this. I noticed something about usernames also. Do I need to worry about not being able to access this db? Thanks for your help, Ben

attach/detach means taking the database offline. if you can do that it’s fast and simple. otherwise you could backup and restore.
you will need to create login names that does not exist on the destination server and for those that exist run sp_change_users_login to fix the SID.

True, using BACKUP/RESTORE solution it would be faster than compared to ATTACH/DETACH.
