An Example of the Attaching Function to Solve Data Overlap Problems

Information worlds are constantly developing in cloud. In data management, the overlapping of data often brings about a lack of data consistency. We consider the attaching function by an equivalent relation in the Incrementally Modular Abstraction Hierarchy to be quite effective to solve the data overlap problem. In this paper, we design a metadata centralized space, a data centralized space, and their Interco version maps using Formula Expression. We then apply them to file data management, where data oftentimes becomes unexpectedly overlapped in metadata schema-centered management. These help users to arrange dynamic worlds from a data-centric viewpoint.
