40. The process of organizing data to minimize redundancy and produce smaller - well-structured relations/tables.






41. Many-to-many relationships occur when each record in TableA may have 0 - 1 or many linked records in TableB and vice-versa.






42. A candidate key that coud have been the primary key but was not selected as such ; OR a field that is not the primary key but has been used for indexing nevertheless.






43. An organised pool of related data files which can be easily accessed and managed and that may be used by a number of different application programs
