WordPress Database Design

Recently i have been working on WordPress plugin and related stuff a lot. There are times when i come across problems with the database of WordPress that required me to check or modify data in the table. However, i couldn't seems to find the correct source for the official WordPress database design which can really help understand a lot of the overall architecture practice of this open source application. But today i manage to find it and would like to share with people out there who can't find it because of various reason (Google fail you).


You can find the most updated version on the WordPress official database design page (the reason why it cannot be found on search engine is because the title of the page is some weird name of the picture)
