I found this great diagram for Magento Database Tables, however, I would like to know if this is still up to date. I am running Magento 1.9. It was published in 2009 and several Magento updates have been rolled out since then. I am hoping that the database structure is still relatively the same. I'd like to get confirmation before I send it to the printer to get a large copy of it.
Also, does anyone know where to find the table definitions? It would be a nice reference to go along with the diagram.
