Hi

I have the following relations (tables) in a relational model

Person
  person_id, first_name, last_name, address

Student
  person_id, matr_nr

Teacher
  person_id, salary

Lecture
  lecture_id, lect_name, lect_description

Attendees
  lecture_id, person_id, date

I'm wondering about the functional dependencies of Student and Teacher.

Do these tables respect the 3rd normal form? Which should be the primary keys of these tables?
