The two imlementation sections use different terminology. That needs to be fixed.

The left-deep definition is still on the Join (SQL) page. That really should be pulled out and merged with the Tree traversal page somehow.

In the Join ordering section, we see "This heuristic reduces the number of plans that need to be considered (n! instead of 4^n)", but n! increase faster than 4^n, did the author wanted the reverse ?
