What is called the number of columns in a table?

A.
Schema

B.
Relation

C.
Degree

D.
Cardinality

Explanation:
In database terminology, is the same to say that the number of Degrees is “X” and
that the number of columns is “X” inside a Table. This question is just trying to test our knowledge
of rare, difficult to fin terminology. You can check this in the knowledgebase of Oracle. When we
talk about degrees, we are just talking about columns. The schema is the structure of the
database, and the relations are the way each table relates to others.
