Does RAILS ensure that multiple users of a RAILS application won’t create a corrupt database
if each user is creating database entries with foreign keys linking multiple tables together?
Do you have to use explicit table locking ?
Thanks,
P.

Rails doesn't do anything by default. You can use optimistic or pessimistic locking of rows if you need to guard against concurrent modifications to a single row. I've never needed table level locking (which is an obvious scalability bottleneck) I personally always use foreign key constraints to enforce integrity of those references
