SQL Question and Answer #4

Question – What is Attribute, Tuple, Domain and Degree?

Thinking that it will be useful to know some of the Basic Term definitions. Inspired from this Question.


Basic, Rows are Records, Columns are Attributes of a Table.


Tuple is a Single row of a Table.


Domain is the set of possible data values that the Attribute supports.


  • Relationship between Schema and Attribute.
  • Relationship between Attributes and every Tuples.
