 Data mining refers to extracting or “mining” knowledge from large amounts of
data. The term is actually a misnomer. Remember that the mining of gold from rocks
or sand is referred to as gold mining rather than rock or sand mining. Thus, data
mining should have been more appropriately named “knowledge mining from data,”
 A data warehouse is usually modeled by a multidimensional database structure,
where each dimension corresponds to an attribute or a set of attributes in the schema,
and each cell stores the value of some aggregate measure, such as count or sales
amount.
