Pretty diagrams can be pretty pointless if they stop at the top. Of course you need an overview to easily see trends but you also need to get down into the data to discover the causes and this should be effortless. If sales are down this month you should not have to dive back into the accounting system and analyse invoices to discover the who and why.
With Bi4Cloud we access the transactions to allow drilling down to detail and pivot and switch dimensions to reveal why and deal with the issue.
You need the detail to do this. When detail matters you need BI4Cloud.
