Data Model

• FileInventoryDifference = compares two FileInventory instances based on file signatures and pathnames

  • FileGroupDifference [1..*] = performs analysis and reports differences between two matching FileGroup objects

    • FileGroupDifferenceSubset [1..5] = collects a set of file-level differences of a give change type

      • FileInstanceDifference [1..*] = contains difference information at the file level

        • FileSignature [1..2] = contains the file signature(s) of two file instances being compared
