Question : Section (sect name, wing, expenses) and Student (student_ID, name, sect name, fees).
Here in both of these relations, the sect_name attribute appears commonly. In this case, using common attributes in the relation schema is a way in which we can relate the ___________ relations.
Option 1: Tuple of common
Option 2: Attributes of common
Option 3: Attributes of distinct
Option 4: Tuple of distinct
Correct Answer: Tuple of distinct
Solution : In left, the related time periods don't overlap if two separate tuples include part ranges that meet or overlap (though they might meet). The associated part ranges don't overlap in right if two separate tuples have time periods that meet or overlap (though they might meet).
Hence the Correct answer is option 4.
