hi everybody,
Please, someone can explain me in what Qlikview is a revolution? because it attack directly an OLTP base without need a datawarehouse? but a lot of tools like Webfocus, reportone or BO do that. Moreover, in what the fact to attack directly an prodcution base by franking of datawarehouse oonstruction is a revolution.
And about the quality of data? about the aberant data? about historical data?
Avoid the construction of a DWH is less costly that is sure but there is a real interest.
Thanks for sharing your experience with me.
Best regards.
