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.
