摘要：A computer system includes a database representing various transactionsperformed by the system. The number of transactions can be quite large. They may form

the basis of analytical processing performed by the computer system, whose results maybe used by subsequent stages of analytical processing. When data errors are corrected,the present invention permits a correction server to identify data entities (analyticalresults or the like) that may now be inconsistent due to the correction. The computersystem may include a data flow manager that monitors data flows throughout thesystem and generates a read history therefrom, identifying reading entities as beingdependent on entities from the database. When corrections are made, the correcteddatabase entities are identified in a corrected entity log. If a comparison between thecorrected entity log reveals a match with an entry in the read history log, the dependententity may be identified as possibly inconsistent.
