An organizational file permission management system using the cellular data system

In designing dynamic situations such as cyberworlds, we the Incrementally Modular Abstraction Hierarchy (IMAH) to be an appropriate mathematical background to model dynamically changing cyberworlds by descending most abstract homotopy level to the most specific view level, while retaining invariants. One of the distinctive features of IMAH is to define an adjunction space (an attaching space) level. Cyberspaces are then attached by an equivalence relation, where the attached areas of the spaces are equivalent. The cellular data system (CDS) we developed based on IMAH is equipped with an automatic attaching function defined on the adjunction space level, and in this paper we have applied the function to organizational file permission information management. The function helps a user to search for the data he/she wants from data storage attaching spaces automatically.
