Enrolment

Hi all

i was looking in database to find which user is enrolled in which courses, i found mdl_course_display which contains all the users and courses which they have accessed. problem is when a student is enrolled in two courses when i remove the student from one course it still maintains the info regarding the acess details of student for that course.

actually i am trying to integrate reports tool to one of our internel statistics site so that's the reason i need information of students who are enrolled into courses, their mapping in database, can anyone help me on this.

thanks in advance
