Database structure – updated for 1.3

As an addendum to this post, there’s a few extra tables in WPMU 1.3, which should officially be released any day now.

wp_1_terms
wp_1_term_relationships
wp_1_term_taxonomy

There are all related to the internal tag system now available in Wordpress 2.3. You may also have noted that MU is now following a similar version number. No official word on how this can be used for sitewide tags, but I know some smart people are in the middle of figuring this out.

I am also working on a database diagram for the next post in this series. My skills are a bit rusty, but the good thing about database theory is that not much changes in twenty years. Just the programs involved.
