Computer database in which all data is stored in Relations which (to the user) are tables with rows and columns. Each table is composed of records (called Tuples) and each record is identified by a field (attribute) containing a unique value. Each and every table shares at least one field with another table in 'one to one,' 'one to many,' or 'many to many' relationships mode .
