I agree with you that there are very few cirumstances where users have valid BI needs for strategic data. While it can do this, I think the real benefit of Real Time DW lies in other areas currently. Area 1 : Smoooooothing that batch window by pre-processing much of the days transactions throughout the day so that come midnight you update some summaries and then exchange some partitions and you're ready. No fighting 8am for reports to be ready. Area 2 : Drill to detail. The data has to get form source to warehouse for the strategic data processing. If you do it in real time you also have the atomic, current operational data there as well. Instead of purchasing and configuring some EII tool to understand data in warehouse and then drill to operational system on the other side of the planet, the DW can have both. Area 3 : "Killer App" I'm working on... :) I'll post some more about this later along.

There is also a question as to why provide information faster than a business can react. I'm even not too sure if 'real-time' dashboards are that much use - if sales for a store dips at 10:00 is it beacuse of a problem with the sales strategy or the local highway is blocked by an accident. Perhaps we need to capture more raw information (weather, highway speed, sickness in the population) to enable better predicitive models ;_ But I do have customers that are moving to realtime capture - it fits their 24x7 sales model. So perhaps I'm saying realtime BI needs a business culture change to use it Just because the technology can do it does not mean we should! - one issue that sometimes gets overlooked is ‘what does my report mean?’ - if I run this report at 9:00am and again 11:00 and the figures are not the same… why?

Didn't like the idea of building a real time mission critical system using a beta product! When OWB goes GA though... :) PS - The Customer Passed and didn’t go for the real time approach.
