[Vtigercrm-developers] Database field for "Assigned To", "Ticket Opened By" and "Ticket Closed By"

[acec acec]

Hi, all
I try to go through vtiger database schema, but I have some questions:

Trouble Ticket Information screen has "Assigned To", "Ticket Opened By" and "Ticket Closed By" field. (Please check my enclosed screen-shot.)

Do you know which database fields are associated with above fields?

Thanks a lot.

Tomcat
