A New Approach to File Directory Systems

概要

論文の詳細を見る
Most traditional file directory systems use tree struc ture. Tree is a simple but weak structure.(1)It fits hierarchical classifications of files well, but precludes non-hierarchical (i.e. orthogonal) classifications.(2)It does not support automatic sharing of files which is often needed by users.(3)It is a single general operating space which becomes more and more complex as a system domain goes larger and larger. So, a new approach is desired. Here we proposed a new directory structure called MSD to solve these problems. Multi-Space Directory (MSD) is proposed to keep the strength and overcome the weakness of tree directory. MSD is different from tree directory in the following aspects:(1)MSD consists of multiple directory spaces (DSs),each DS is an operating domain;(2)MSD is a set hierarchy which fits both hierarchical and orthogonal classifications of files, and supports both vertical and horizontal automatic sharings of files. We describe the structure of MSD in the next section and summarize its characteristics in the conclusions.
