Charactersctics of Relation

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.
