Business Intelligence The above statement is false. BI applications use data gathered from a data warehouse (DW) or from a data mart, and the concepts of BI and DW sometimes combine as "BI/DW" or as "BIDW". A data warehouse contains a copy of analytical data that facilitates decision support. However, not all data warehouses serve for business intelligence, nor do all business intelligence applications require a data warehouse. Prajakta Pandit 04-3-2017 01:59 AM

DW vs Data mart Other options are, You can go with Data marts or depending on operational reporting needs, ODS (Operational data Store) would be an another option. Harshad Hardas 12-25-2014 05:08 AM
