Hello. I am on Lesson 15 of this seminar and I think I finally (after several weeks of off and on studying/questioning) understand how I need to create my database. I do want to make sure I understand, though: I read that many to many relationships are just two one to many relationships joined by a junction table, but that isn t quite right, is it? For example, a one to many relationship would be A can have zero to many of B, but B could only have zero to one of A, correct? Like I read a street can have zero to many houses, but a house belongs to (well, not zero but) only one street. But a many to many says,  A can have zero to many of B AND B can have zero to many of A, correct? Like a room can be booked by zero to many guest, and a guest can book zero to many rooms. So, in that way, it s that quite the same, correct? Am I on the right track?
