A relation is a two-dimensional table in which (1) the entries in the table are single-valued; (2) each column has a distinct name; (3) all of the values in a column are values of the same attribute; (4) the order of the columns is immaterial; (5) each row is distinct; and (6) the order of the rows is immaterial. 2. A relational database is a collection of relations. 3. An unnormalized relation is a structure that satisfies all the properties of a relation except the restriction
