Lotsa joins

Couldn't find it in the manuals...is there a limit to the number of
tables that can be joined in a single query?
Is there a better way of joining a central table through several bridge
tables to their lookup tables?

No limit, in fact, we have GEQO which automatically reduces problems
with expoential growth of optimizer choices.
