In designing dynamic situations such as cyberworlds, we consider the Incrementally Modular Abstraction Hierarchy (IMAH) to be the most appropriate among existing data models. It can model both cyberworlds and real worlds by descending from the most abstract homotopy level to the most specific view level while retaining invariants such as topological equivalence. We have developed a data processing system based on IMAH called the Cellular Data System (CDS), and in this paper we have newly added to CDS an automatic attaching function defined on the adjunction space level. The function helps a user to search for the data he/she wants from data storage attaching spaces automatically. Additionally, we gave an example of personnel resource management to verify the effectiveness of the function.
