System for accessing remote heterogeneous database including formatting retrieved data into applications program format

摘要

An improved method for access to data from a remote computer and an improved method for accessing remote heterogeneous data bases. The method includes a personal computer having an application program for processing data by keyboard input that operates on a local applications data base having files with a first file structure. A remote host computer accesses data in remote files having a second file structure. A preselected keystroke of the first computer modifies the data accession program of the remote computer to reformat retrieved data in the format of the personal computer applications program before transmission back to the personal computer, so that the personal computer resident portions of the program require no information as to where the requested data is located or what the host computer file structure is.
