See https://developer.atlassian.com/server/jira/platform/database-schema/

But don't - the database is not suitable for reporting, it's the worst single way you can possibly read Jira data (and you certainly won't be using it for write).

If you can tell us why you are asking this question, we can probably point you at the right way to achieve what you want.
