Methods for calculating a combined impact analysis repository

摘要

Methods for accessing impact analysis repositories and transaction-refinement index for each of the impact analysis repositories. According to the obtained transaction-refinement index, associating the combined repository with information from the most transaction refined impact analysis repository. Associating the combined repository with information from the less transaction refined impact analysis repository in the case of a request to insert or delete a table record for tables that do not contain any impacted transaction in the more transaction refined impact analysis repository. And associating the combined repository with information from the less transaction refined impact analysis repository in the case of a request to update a table record for table columns that do not contain any impacted transaction in the more transaction refined impact analysis repository.
