Answer Posted / nameer
Datawarehouse(OLAP):
To store historical or years of data, we use datawarehouse.
So it will be usefull for managerial people to analyse
theire current scenario with old one and take some usefull
decision in the future to improve their business.
We load the data into datawarehouse using some ETL tool
which is called datawarehousing where as in normal database
we use insert operation. in datawarehouse no delete,update
or insert operation is used. Only select operation is used.
It uses the dimensional modelling(star or snowflake) schema
which will speed up the retrieval of data comapred to
ordinary database.
