I'm a newcomer with Moodle. So if I posted in wrong box, please let me know.
I'm creating a report which analyzes number of questions in each course by question categories. I tried to find the relationship between the mdl_course table with mdl_context, mdl_question_categories and mdl_question table but I can't understand which relationships exist between these tables? How can a mdl_question_categories is a sub branch of a course?
Thanks for any help.
