Question

question 9
which of the following relationships describes one row of data in table a associated with many rows of data in table b?
a many - to - many
b one - to - one
c one - to - many
d none of the above

Explanation:

• many - to - many: This relationship means many rows in Table A can be associated with many rows in Table B. For example, students (Table A) and courses (Table B). A student can take many courses and a course can have many students. But this is not the case described in the question.
• one - to - one: Here, one row in Table A is associated with exactly one row in Table B. Like an employee (Table A) and their unique employee ID card (Table B). This is not the relationship we want.
• one - to - many: In this, one row in Table A is related to multiple rows in Table B. For instance, a department (Table A) and employees (Table B). One department can have many employees. This matches the description in the question.

Answer:

C. one - to - many
