Patent ID: 8032475

Claim:
A computer-implemented method comprising: receiving an abstract rule having (i) a conditional statement and (ii) a consequential statement defining a particular result returned by the abstract rule for a given set of input data supplied to the abstract rule, wherein the conditional statement is composed from one or more logical fields, and wherein the logical fields are defined in a data abstraction model modeling an underlying physical database; receiving a set of query results comprising a plurality of data records, each including one or more input values; sorting the plurality of data records into one or more groups, wherein each group includes data records having a common set of input values; and for each group of data records, processing the input values associated with the group against the abstract rule, wherein processing the input values comprises determining whether the abstract rule is deterministic, and setting, as an output of processing the input values, a result returned by the abstract rule for each data record in the group.
