Is the suitecrm database schema available online anywhere? Something that illustrates the relationships between all the tables. I saw one for sugar, but the relationship lines were a squiggly mess.
Not official yet, but will probably be useful for you

There are a few custom tables in there that don’t belong in a default installation, but nothing too relevant.
To avoid the “squiggly mess” (I like this term), use the view by single table, scroll to the bottom, and you will see a drawing with only the tables directly related to that one, or separated by one level.
