Reports

Hi, I´m new in ServiceDesk Plus and I wanna generate some reports using the new query report button. I have a few question:

What is the name of the tables in ServiceDesk Plus database where I can find the technicians, categories, subcategories, requesters?
There´s a documentation that can help me to know the ServiceDesk Plus database?
What is the query to associate categories and subcategories?

Best Regards
