Abstract
A computerized analyzer for a transactional data stream prepares feed records from the data stream, the feed records comprising all transaction records received in a finite time slice. A new feed record is prepared for each passing time slice, and, in a preferred embodiment, new time slices are generated during operation based on record volume received during a previous time slice. The feed records are condensed to significant feed records by selecting only those transaction records in each feed record that are significant according to prestored criteria including subscriber interest records. Once a significant feed record is prepared, it is compared with subscriber interest records to produce an alert table. An alert transmitter transmits alerts to subscribers following the alert table. Alerts are deleted from the alert table as they are sent to subscribers. The system is suited to many types of transactional data streams, and suited for such as stock quote data streams.
