1. A realtime event processing system, comprising: an access component configured to access heterogeneous data sources of event data that corresponds to assets represented by a composite of related static event data and realtime event data; a synchronization component configured to time synchronize the realtime event data and static event data of the assets, as obtained from the heterogeneous data sources; a realtime merge component configured to merge the synchronized realtime event data and static event data into a realtime event stream through one or more operators, to define the synchronized realtime event data and static event data into assets queriable as a single event type for continuous event processing to return multiple related asset items; and a microprocessor that executes computer-executable instructions associated with at least one of the access component, the synchronization component, or the merge component.
