The invention relates to a system handling a plurality of data sets stored in different repositories (310, 320), the system comprising a data managing unit (200) configured to provide processing rules for processing the data sets stored in the different repositories, the processing rules including access rules providing information which of the data repositories should be accessed in the case of a data access request for one of the data sets, the processing rules further including consistency enforcement rules providing correction actions when an inconsistency for said one data set stored in different data repositories is detected. Furthermore, a virtualizing unit is detected which is configured to control data access requests for the data sets and configured to enforce the processing rules provided by the data managing unit (200), wherein, when the data virtualizing unit (100) detects the data access request for said one data set, the data virtualizing unit handles the data access request for said one data set, accesses at least two repositories (310, 320) where said one data set is stored based on the access rules, and corrects a detected inconsistency for said one data set based on the consistency enforcement rules. |
