Claim:
A correction server system, comprising: a database storing a plurality of data entries; a computer system including one or more hardware processor(s) executing program instructions to instantiate: one or more analyzers, executed by the processor, to read data entries from the database according to respective read requests and to calculate analytical results therefrom; a data flow manager, responsive to read requests from the analyzers, to store data representing the read requests in a read history, the stored data including, for each read request, identifiers of a data entry read and an analytical result generated therefrom; and a correction server, responsive to a write to a data entry in the database to correct that data entry, to: compare an identifier of the corrected data entry to data entry identifiers stored in the read history and, when a match occurs, identify a previously-generated analytical result corresponding to the matching data entry identifier of the read history as rendered potentially inconsistent by the data entry correction.
