Abstract
A database system is provided for interchanging visually faithful renderings of fully formatted electronic documents among computers having different hardware configurations and different software operating environments for representing such documents by different encoding formats and for transferring such documents utilizing different file transfer protocols. All format conversions and other activities that are involved in transferring such documents among such computers essentially are transparent to their users and require no a priori knowledge on the part of any of the users with respect to the computing and/or network environments of any of the other users. All database operations are initiated and have their progress checked by means of a remote procedure call protocol which enables client applications to obtain partial results from them relatively quickly, without having to wait for such operations to complete their work. These database operations are forked as child processes by a main database server program, so the functionally of the database system may be extended easily by adding further database operation programs to it.
