Data mart is subset of dataware house
In Brief: Assume that there is an company called vijayJDK,
and it is havaing 4 dept
1:petrolium
2:deisel
3:kirosine
4:crudoil
now if you develop dataware house for any of them above 4 dept's we call them as datamarts,and then if you consolidate 4 dept's then ,that will be called as dataware house |
