A consistency checker and (200) a method performed by a consistency checker (200) for finding inconsistencies of data posts stored in a data repository (220) is provided. The consistency checker (200) has a storage unit (202) in which a number of inconsistency patterns are stored, each inconsistency pattern being associated with an inconsistency analysis rule for a value of a data attribute. The consistency checker further has a receiving unit (204) for receiving a data post from the data repository, and a logic unit (206) arranged for matching a value of at least one data attribute of the data post with a value of the corresponding data attribute of the stored inconsistency patterns, and if there is a match, applying the inconsistency analysis rule that is connected with the matched inconsistency pattern to the data post to evaluate whether there is an inconsistency in the data post or not, wherein the number of inconsistency patterns each defines an inconsistency that has previously occurred for a value of a data attribute in the data repository. |
