alleryStart learning →A ternary relationship has degree
A1; a single entity set is involved
B3; three entity sets participate in each tuple
C2; two entity sets always sandwich a relationship
Dany value strictly greater than 4
Answer & Solution
Correct answer: B. 3; three entity sets participate in each tuple
NPTEL defines degree as the number of participating entities.
Binary = 2, ternary = 3, n-ary = n.
**A common ternary case:** a Supplier supplies a Part to a Project.
The relationship has three entity sides
one tuple has one value from each.
