Mmmm....

 I have been working on a couple of OLAP projects, finally the tools that
we have used to browse the reports are SSRS and Proclarity Analytics
(Professional edition, no I think it's named PPS).

 But the scenario that yo uare commenting (auto refresh when data changes)
I haven't seen it directly implemented on this tools.

 To make this "Is Data changed" check on the client side I would:

  1. If the page showing the data has to show other information, just use
AJAX ASP .net and call a web service from the javascript side asking if there
has been changes, in that case perform a post (or update panel) in order to
update the page).

 2. If you are just showing a gird (or an embedded SSRS report on an
iframe), you could wrap it in an update panel and set a property on that
panel to check for update on the server every X seconds.

 Good luck
