This type of data is referred to as "intersection" data because it represents the intersection between students and courses, detailing not just the relationship (which students took which courses) but also specific attributes of that relationship (the semester when the course was taken and the grade received). This contrasts with terms like "index" or "key" which are more about data structure and access methods, "pointer" which refers to a data type that holds memory addresses, and "direct access" which is a method of accessing data.
