Case Study: An Organizational File Permission Information ManagementSystem4.1 OutlineWe have developed a business application system for managing file permission informationin an organization using CDS. In this system, file permission information is managed underthe assumption that its organizational structure or relations among staff and theirassignments or file structure often change. In this section, we simplify all data withoutlosing generality. This system is currently being used by companies in Japan such as ACS,Inc. and Maeda Corp. to manage file permission information.4.2 The Space DesignWe design a formula for the spaces as follows.1. A formula for organization data for the company as a topological spaceOrgInfo(Σmonthi(Σnodei,1(Σnodei,2(Σ…(Σnodei,j(Σstaffi,j,k)))))node: a factor which expresses the node of an organizational structuremonth: a factor which expresses month data2. A formula for file permission data for files as a topological spacePermissionInfo(Σnodei,1(Σnodei,2(Σ…(Σnodei,j(Σstaffi,j,k×permissioni,j,k×monthi,j,k×filenamei,j,k)))))filename: a factor which expresses file name datapermission: a factor which expresses file permission data of r meaning readable or wmeaning writable
