General : Multiple tables, Entity Beans, Performance

| Hi
Lets say I have these entities
Person, Account, Cars
Now lets say I have an entity for a person an entity for account and
an entity for a car.
I guess queries that will join all three tables are more expensive
than ones that query only one entity...
Is there any pattern any thing that tells me what to do, how to
improve my performance (if needed at all with the fact that EJB's are
supposed to do caching etc and improve performance) that will tell me
what to do ? with queries from 3+ tables / entities ?
