Patent ID: 10776746

Abstract:
A system for tracing a plurality of items considering an interface configured to receive an event data record including operation information indicating an operation, time information indicating a time when the operation occurred, and identification information identifying at least one item, a data store configured to store state information indicating one or more states for each one of the plurality of items, and a processing unit configured to receive via the interface one event data record. The processing unit is configured to, in response to receiving the event data record and for the at least one item identified by the identification information included in the received event data record, generate, based on the received event data record, state information indicating a state of the at least one item after the operation, query, from the data store, preceding state information indicating a state of the at least one item directly before the operation, and succeeding state information indicating a state of the at least one item directly after the operation, evaluate, if preceding state information was retrieved in response to querying the data store, a transition between the state indicated by the generated state information and the state indicated by the preceding state information for a first rule conformity, and to, evaluate, if succeeding state information was retrieved in response to querying the data store, a transition between the state indicated by the generated state information and the state indicated by the succeeding state information for a second rule conformity.
