Abstract
A computer system retrieves from data repositories change information indicating changes to entries. Each data repository is associated with a corresponding interface and at least two data repositories are associated with different interfaces, and at least one data repository lacks tracking of changes to entries stored therein. The change information retrieved from the data repository is stored within a storage unit. The stored information includes identification of each repository entry change without storage of the changed entry. Requests are processed to provide change information for entries within the data repositories, wherein processing the change information request for one of the entries includes retrieving from the storage unit the identification of the repository entry change for the one of the entries. Embodiments of the present invention further include a method and computer program product for tracking changes within data repositories in substantially the same manner described above.
