Did you ever hear about the Microsoft Dynamics AX Entity Store? What should you buy there? One of the over 1.600 entites the new Dynamics AX contains? No, nothing to buy. The entiy store is the leak of cubes, the eol of etl. Minutes after transactional data are committed to the new Dynamics AX OLTP database these data are businessready normalized to base entities and can be consumed by the BI Tools. User can query and aggregate operational data within minutes after the deal was done. The times to extract, load, transform data and prepare cubes seems to be gone.
