A method for performing real-time analytics using a business rules engine on real time heterogeneous materialized data views is disclosed. The method comprises processing of rows produced by views corresponding to events. The rows are processed according to business rules by a view engine. Views with conditions equivalent to rule conditions are subscribed to by a rule engine, which outputs action messages corresponding to the rule condition. Where the rule condition is satisfied, a statement to that effect is sent, with any available reportlets, to an alert engine. The alert engine handles alert states corresponding to the action statement, saves any corresponding reportlets, and generates a message to fire an alert to a notification engine. The notification engine formats the alert and sends the alert by a selected medium, such as email, a webservice call, or another network protocol.

A method for dynamically initializing a view for a streaming database system. The method includes accessing a stream of events. An initial view is materialized from the stream, wherein the initial view comprises a dynamically defined view of the stream of events from the streaming database system. The method also includes processing a plurality of recent view snapshots from the initial view. A view state derived from each of the recent view snapshots is generated. An updated view is subsequently maintained in accordance with the view state, wherein the updated view incorporates new events of the stream.
