Expensive data warehouses not always necessary for BI
Expensive data warehouses not always necessary for BI: "At the very least, said Joshua Greenbaum, principal analyst with Enterprise Applications Consulting in Daly City, Calif., companies that must build a data warehouse -- a historical data repository for the purpose of analysis and reporting -- don't need to pour as much money into it as they may think.
'One of the fallacies has been that BI has to start with a very expensive and complex data warehouse,' Greenbaum said in a phone interview. 'There has been a lot of money spent on data warehouses and not necessarily much value gotten out of them.'
Before jumping into a data warehousing project, Greenbaum said companies should first see how far they can get with simple analyses of transactional data -- analyses that do not require large quantities of historical data. "
