Abstract:
A method of synchronizing redundant data in a plurality of dissimilar external electronic database files, comprising the steps of:(a) for each such external data file, determining the data field and record structure of the database, and creating a format file describing said structure;(b) determining the addressable location for each such external data file;(c) for each such external data file, creating a data link file which associates its format file with the text field in a database used to hold the data;(d) in response to desired modification of any of the data which is held in more than one of said external data files, for each described modification, applying a change to the data in the affected data files; including;(e) comparing said change to said format files as associated with each of the said external files to determine which external data files need to be updated;(f) using link files, format information, and address location to update the data fields in the affected external data files to correspond with the change; and(g) repeating steps e and f until all affected external data files have been updated to reflect the changed data.
