Abstract: The method includes steps for creating and or modifying the organizational structure and data content of a frame-based, hierarchical product database with the use of tabularly arranged product data. The method features steps for enabling determination of a hierarchical database organizational structure capable of accommodating importation of tabular product data. Additionally, the method feature steps for facilitating either modification of an existing organizational structure where the database already exists, or, creation of a new frame-based, hierarchical organizational structure suitable for receiving the tabular data by generating an entirely new, original structure where none is available.

Abstract: In response to the users actions relative to graphical representations of a multiple inheritance concept hierarchy to delete, add or modify the relationships between the various concepts, property declaration, property constraints and relationships therebetween, this system first, recognizes and disambiguates possible semantic incoherance introduced by the changes; second, suggests alternative procedures to ameliorate any perceived incoherence; third, interactively allows an agent (user or machine) to select from one of the alternatives; and fourth, performs the sequence of necessary operations to resolve semantic incoherence in the modified hierarchy.
