A method, system and computer program product for creating a report on the basis of a plurality of remote datasets includes an intelligence server, one or more tree servers and one or more databases. Each tree server creates one or more segments, or slices, of a report, using information that resides on the tree server. Slices are aggregated into a tree structure, and the tree structure is converted into a report. The intelligence server receives updates from the tree servers. The tree servers and the intelligence server remain in communication for the purposes of passing update messages. The update messages are received and processed at the intelligence-server in a manner that facilitates synchronization with the contributing tree servers and provides live updates to the user.
