Speaking with our clients, I’m often reminded that C-Level and Senior Managers still need to understand why you’d need to build a Data Warehouse, and ultimately what the organization will gain from money invested into it.
I had a dig back over my collected articles/links and re-discovered a couple of good slideshare.net presentation which present a good case for building Data Warehouses.
I also found it worthwhile to revisit what Ralph Kimball had to say on the subject;
“The goal of a data warehouse and business intelligence (DW/BI) solution is to publish the “right” data and make it easily accessible to decision-makers. Successful DW/BI implementations rest on the foundation of a dimensional model to deliver both ease-of-use and query performance.”
I’d be interested to hear about your ideas/success stories of what works with the C-Level when talking about the need for a Data Warehouse.
