Abstract:
A method for automatically maintaining data consistency across two or more hierarchically arranged databases, said method comprising the steps of:creating a master list and an environmental variable file for use in maintaining data consistency for a cell view;determining if said cell view in a selected database has been modified by performing date-timestamp shadowing;responsive to said determination, retrieving said cell view based on derivative lists created from said master list and said environmental variable file from said selected database;translating said cell view based on criteria from said environmental variable file;performing verification on said translated cell view based on criteria from said environmental variable file, said verification creating a signature for said translated cell view;determining if said translated and verified cell view has been altered by performing an audit based on criteria from said environmental variable file using said signature; andpromoting said translated and verified cell view to a higher quality database among said two or more hierarchically arranged databases based on results of said audit.
