1. In a system having local processors each connected to a located memory, a communications channel between the local processors, and a data base of a multiplicity of data varibles distributed over the local memories, an improvement to a method of operating a Distributed Data Base Management System (DDBMS) by executing at the local processors local programs, which are referencing the data variables within the data base, and originating each data variable at an originating one of the local processors, the improvement to the method of operating a DDBMS comprising: first locally storing in each local memory an original of each data variable which is originated by the associated local processor; second locally storing in each local memory a copy, obtained across the communication channel, of each data variable not originated by the associated local processor which each data variable is at any time referenced by the associated local processor; WHEREIN both the first and second locally storing of each data variable is at an absolute address, meaning an address designation of the local processor which does originate the data varible in addition to an address in local memory at which the data variable is first locally stored; referenceing, responsive to a local program executing on each local processor which local program makes references to data variables, each data variable only at the absolute address of said data variable supplying, responsive to said referencing, each data variable from the assoicated memory of the local processor making reference, regardless that the data variable should be the original or the copy; executing a procedure within each local processor, called by the local program executing therein, for updating the copy of a data variable stored within the associated local memory by obtaining the original of the data variable across the communication channel.
