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 ?

merge with query optimization?

There's a separate page on query optimization (which looks unfinished). Shouldn't they be merged? Eclecticos (talk) 04:23, 6 December 2007 (UTC)[reply]

I think that Query Optimizer be a sub section under Query Optimization. —Preceding unsigned comment added by 196.3.94.70 (talk) 15:48, 30 March 2009 (UTC)[reply]

I think it should be left as such with just providing link in both pages to access each other..

The query optimizer is the component of a database management system. Query optimization is the goal of technical rewriting/changing the query by either, the query optimizer, automated tuning software (e.g. query hints) or manual intervention (e.g. create index). In other words both are different encyclopedia entities which surround the same topic.

I think there is unlikely to be enough distinction between these two topics to merit two separate articles. For example, we don't have separate articles for pile driver and pile driving, nor for teacher and teaching, nor for editor and editing. --P3d0 (talk) 01:59, 21 November 2009 (UTC)[reply]
