  • A data modeling example of File Permission management using the cellular data system
    2010
    Co-Authors: Toshio Kodama, Tosiyasu L Kunii, Yoichi Seki
    Abstract:

    In the era of cloud computing, data is processed within "the cloud", and data and its dependencies between systems or functions progress and change constantly within "the cloud", as user requirements change. Such information worlds are called cyberworlds. In designing cyberworlds, the Incrementally Modular Abstraction Hierarchy (IMAH) gives a most appropriate mathematical background to model dynamically changing cyberworlds by descending from the abstract level to the specific one, while preserving invariants. An attaching function is defined on the adjunction space level to model attachment of spaces by an equivalence relation in IMAH. In this paper, we have improved the attaching function to the Cellular Data System (CDS) that we developed based on IMAH. The function is quite effective in business application development when a system user recognizes an equivalence relation in business objects. We have also shown an example of the use of CDS for File Permission information management under an unexpected situation, such as when an organizational structure or its staff assignments change, using CDS. In the example, we design and take advantage of spaces on three of the seven levels of IMAH, in order of abstractness: the set theoretical level, the topological space level and the adjunction space level.

  • an organizational File Permission management system using the cellular data system
    International Database Engineering and Applications Symposium, 2009
    Co-Authors: Toshio Kodama, Tosiyasu L Kunii, Yoichi Seki
    Abstract:

    In designing dynamic situations such as cyberworlds, we consider the Incrementally Modular Abstraction Hierarchy (IMAH) to be an appropriate mathematical background to model dynamically changing cyberworlds by descending from the 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.

  • NOMS - Managing the File system from the kernel
    2014 IEEE Network Operations and Management Symposium (NOMS), 2014
    Co-Authors: Shihabur Rahman Chowdhury, Constantin M. Adam, John J. Rofrano, Raouf Boutaba
    Abstract:

    In this paper, we investigate the benefits of adding autonomic capabilities inside the operating system. We have developed and implemented a solution that focuses on three use cases (continuous File Permission compliance, dynamic disk cleanup, and accidental removal protection) for the File system, and encapsulates all the respective File system monitoring, troubleshooting and error remedial operations in a Linux kernel module. The main benefits of this approach are the capability to detect issues instantly when they occur, and fix these issues transparently, with the invoking applications being unaware of their occurence. These capabilities are not present in external agent architectures, including contemporary configuration management systems, like Puppet, Chef, or CFEngine. We have built a prototype and evaluated the performance of the most resource intensive use case, dynamic disk cleanup, using the FileBench File system benchmarking tool.
