Method of efficient target query selection ranging
Abstract:
A method for providing efficient target parameter selection ranging includes assigning each record at least one persistent identifier. The persistent identifier may be ordered so that a selected range of the persistent identifier may allow a user to select a number of consecutively-identifiable, but apparently randomly-selected records. By only choosing records from a range of persistent identifiers, mutually exclusive or disjoint sets of records may be efficiently selected without performing a database join operation or storing the lists for comparison or later use. In one example, the persistent identifier may be a large random number assigned to a record at is creation.
