METHOD FOR SELECTING, VERIFYING AND PROCESSING PREFIX DATA IN EXCHANGE DATABASE

摘要

PURPOSE: A method for selecting, verifying and processing prefix data in an exchange database is provided to efficiently carry out the verification of prefix data by enabling a verifier to extract practically necessary portions from complicated prefix data. CONSTITUTION: A verifier selects a necessary dataset and an item. After the selection, the verifier executes verification processing for the selected dataset and item, appointing the paths of an old version IROF(Initialized Relational Object File) and a new version IROF for them(72). Then the verifier extracts only the information of the selected dataset/item from the verification processing result(74). The user carries out old/new dataset comparison for the extracted dataset/item information and outputs a comparison result(76).
