CHARACTERSTICS OF RELATION

 

1)      No Duplicate Tuples - A relation cannot contain two or more tuples which have the same values for all the attributes. i.e., In any relation, every row is unique.

 

2)      Tuples are unordered - The order of rows in a relation is immaterial.

 

3)      Attributes are unordered - The order of columns in a relation is immaterial.

 

4)      Attribute Values are Atomic - Each tuple contains exactly one value for each attribute.

 

5)      It may be noted that many of the properties of relations follow the fact that the body of a relation is a mathematical set.
