Database ERD

Good day,
Accepted answer

I believe this is usually proprietary, and guarded as trade secret. No?
I think you should stick with the supported way of reporting.

That answers my question. Thank you Donald.

I wouldn't call the database tables proprietary or a trade secret, but they are subject to change on each release, so we strongly recommend not trying to code directly against them because you would have to verify all of that code and possibly recode on every release. Because of that, the format is not documented, and you would not receive any support if you tried to code against them.
