摘要

A system for linking elements representing stored information in a data base comprising a link structure formed in a section of the data base independent of the elements, a pointer in the link structure indicating the location of a first element, and a second pointer in the link structure indicating the location of a second element. The data base contains items comprising textual data and a plurality of categories into which the items may be categorized such that each item may be linked to more than one category. The invention automatically assigns an element in a data base to a parent category if it has been assigned to a child category of the parent. The invention will allow a user to modify data in a data base in a view mode, and will resolve ambiguities by guessing as to the most likely interpretation intended by the user. The invention will allow a user to change the number or organization of categories in the data base while the user is in a view mode.
