ABSTRACT:
A method of maintaining a distributed database among independently operable sites in which database availability is not interrupted during database update. Commands are provided to each of the sites and the database is assumed to be updated unless otherwise indicated by responses from the sites. Site operation continues whether a command has been executed properly or improperly or not at all, and commands are subsequently repeated until executed properly at all sites. Commands for acting on data in the database are classified by selected characteristics, and may be executed by class to facilitate exploitation of the data in the database. The method is disclosed in an electrical power distribution system in which data in a distributed database is used at plural independently operable command centers for the operation thereof.
