A system for managing a distributed database of electronic data files is provided. The subject distributed database management system (10) 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 from the first site, and one or more user platforms (300) disposed at third sites remote from the first and second sites. The storage facility (200) and each user platform (300) are computer network coupled to the host platform (100) for communication therewith. 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. The host platform (100) 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. It includes a plurality of application modules selectively executable responsive to actuation by a user platform (300). The host platform (100) is thereby operable to selectively retrieve at least portions of the electronic data files for graphic reproduction at a user platform (300).
