Answer 1

Answer:

Explanation:

In a "class roster" database, a teacher may teach zero or more classes, while a class is taught by one (and only one) teacher. This kind of relationship is known as one-to-many. ... The one-to-many relationship cannot be represented in a single table. A direct many-to-many relationship can exist between two relational tables. The STUDENT table contains one row for each student enrolled at a college, and the CLASSES table contains one row for each class offered at the college. Each student can take many classes, and many students can take each class.
