With regard to claim 2, appellants argue that IBM does not show the claimed “wherein the superset is limited to a derivation set of the target view tuple.” We disagree.

It is clear that the target view tuple (x, y, z) is a derivation of the broader (x, ?, ?) tuples constituting the “superset.” With regard to claim 4, appellants argue that this claim requires a transaction T to issue the read-lock-request and that prior to the issuance of the request, the transaction T declares a read set which contains all data to be read by transaction T. It is appellants’ view that the applied references do not suggest this limitation. We disagree.
