In a data linking method of extracting data of a host data base on a computer into a portable remote terminal, an item definition data base which defines a record attribute, an object storage data base which stores object data on a record basis, a relation definition data base which defines relations among object data and a definition data base which defines relations among the respective data bases, and conducts synchronous processing of writing. The portable remote terminal conducts link data solution processing based on a record attribute of the item definition data base when a record item of the object storage data base refers to other object storage data base, and changes, when the display order of object data of the 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 the computer further reads an updated record from said object storage data base of the portable remote terminal to update the host data base.
