Abstract:
A System for linking data between a computer and a portable remote terminal which extracts data of a host data base on said computer into said portable remote terminal, displays and edits the extracted data on said portable remote terminal and conducts synchronous processing of updated data in said portable remote terminal and a data base in said computer, whereinsaid computer comprissing:means for selecting object data to be brought out from said host data base into said portable remote terminal and a record item of the object data;means for creating on said portable remote terminal, with respect to selected object data, an item definition data base which defines a record attribute, an object storage data base which stores object data on a record basis correspondingly to said item definition data base, a relation definition data base which defines relations among object data stored in said object storage data base and a definition data base which defines relations among the respective data bases created;means for writing, on the basis of a record taken out from said host data base, data into the corresponding one of said object storage data bases according to said item definition data base; andsynchronization means for conducting synchronous processing of reading updated data from said object storage data base of said portable remote terminal and writing the data into said host data base of said computer; andsaid portable remote terminal comprising:means for conducting, when a record item of said object storage data base refers to other said object storage data base, link data solution processing based on a record attribute of said item definition data base; andmeans for changing, when the display order of object data of said object storage data base is changed or when existence/non-existence of display is selected, the display order of object data of said item definition data base or an attribute indicative of existence/non-existence of display according to the contents of the change or the selection; and whereinsaid synchronization means of said computer reads an updated record from said object storage data base of said portable remote terminal to update said host data base of said computer.
