Abstract
A customer signature or other type of record in a database system is updated using an event-driven estimator based on a model of time-dependent behavior. In a preferred embodiment, a current version of a record affected by a given transaction is retrieved from a memory of the system and an event-driven estimator of at least one of a transaction rate and a period probability for the record is determined based at least in part on a dynamic Poisson timing model having a number of periods and corresponding period-based transaction rates associated therewith. The event-driven estimator may be configured so as to generate an estimated transaction rate {circumflex over (&lgr;)} for period j and a given transaction n, and then to generate an estimated period probability {circumflex over (&pgr;)} for period j as {circumflex over (&lgr;)} /&Sgr; {circumflex over (&lgr;)} . An updated version of the record may then be generated based on the event-driven estimator.
