15 years ago when I joined workforce business intelligence was all the rage. Data world was pretty much straight forward. You had transactional data in OLTP databases which would be shipped to Operational data stores, then rolled into the data warehouse. Datawarehouses were actual specialised hardware appliances (netezza et al) reporting tools were robust too. Everytime I moved from one org to another, these concepts of data warehouse somehow got muddled. |
