A system ( 10 ) for managing a distributed database of electronic data files generally includes at least one host platform ( 100 ) disposed at a first site, at least one storage facility ( 200 ) disposed at a second site remote therefrom, and one or more user platforms ( 300 ) disposed at third sites remote from the first and second sites. The storage facility ( 200 ) retrievably stores a plurality of electronic data files for generating graphic images. The host platform ( 100 ) is configured to automatically control access by user platforms ( 300 ) to the electronic data files and maintains a system index table containing for each of the stored electronic data files at least one file record of identifying attributes corresponding thereto. The host platform ( 100 ) is operable to automatically generate the file record in accordance with a preselected set of configurational parameters and to selectively retrieve at least portions of the electronic data files for graphic reproduction at a user platform ( 300 ).
