I recently spoke to a friend of mine who works as a business intelligence consultant about writing an article for Information Management with a new twist on the operational data store which I call DORDS. After a moment of silence, he said, A what? I said, A DORDS. Its a dimensional operational reporting data store. Then he asked, in his very low gravelly voice, You have my attention. So I proceeded to describe a recent project I had completed for a very small startup company with a unique business model.
Last year, I was contacted by a representative of this large company about my expertise on building data warehouses. For about 15 minutes, they described their business in general terms and their desire to create a data warehouse. I listened intently and took many mental notes. Taking a few minutes to gather my thoughts, I proceeded to describe several options. One option is to create an operational data store, which would alleviate the biggest problem of executing complex report queries against a transaction system. I proceeded to describe what they could do with this ODS and how they could subsequently create a real data warehouse as the main repository at a future date. We also discussed the transaction database issues, hardware configuration and their network.
