 Problem Statement:   encoding data on a medium ...efficiency, effective-ness

                      leveraging bit (union or struct or string ...using a nth positional bit as a flag to represent boolean data ),
                      based data encoding , leveraging numerical-constants ...code-based comparision

                      further to as published in projects.pdf , ...as advocated on this uri/url.

 Opportunity :  example in GUI based operating system ...interfaces to assign permission's to various object's,entities.

                eg: allocation of permission on a folder/virtual-folder  i.e. access to user's ...classification of user's based on various criteria

                taking the above as a scenario ...scope context of evaluation of the scope ...permission on a object/entity inter/intra relationship's
                between these entities ...ability to encode, represent ...efficiently evaluate in the context.

                difference between a directory , folder and a virtual-folder ...amount of information that needs to be encoded in representing the
                object.

 

                use-case-modeled scope for the above context : understanding 'n' bit architecture computing model.
                ---------------------------------------------

              1) in the context using dynamically evaluatable constants in a drop down the interface used to allocate the permissions (i.e. all the
                 list of value's in a allocatable drop-down options interface are evaluatable constants)
                
                 do the summation of the constants represent effective permissions on the object, if summation how are the various classes or groups
                 at each 'summation' level represented.
             
              2) perl anonymous hash , array ...iteration evolution....understanding a in-memory database , ram-disk , perl-data::dumper ...refer
                 to some of the work's executed at veritas corp.

              3) understanding and evaluating 1),2) vis a vis ...a bit based representation....understanding evaluation of 'umask' amount of 
                 information encodable in a byte-length.

        ....apply appropriate
      'use-case' modeling, rationalize and arrive at a workable and feasible 
       solution both commercially and techinically viable.
