Problem statement :  COBOl has been the choice of business systems ...traditionally
                     and has been designed so.

                     Evolution of RDBMS....functions or code logic that can be accomplished using RDBMS(searching,indexing )  

                     further to as illustrated in projects.pdf ...usage of a disk-medium(custom disk drive with custom read head
                     that does io along the radii ...platter or disk) as a sequential record holding for
                     ultra-high speed access ...while can be contrasted with a tape for the same with reference to rewind viz.
                     fseek ...offset forward backward ...and scope for a custom driver driven tape-medium as in a tape-recorder,
                     thus a library of file,stream handling function's for the tape media on the lines of a header file or
                     module.         

Opportunity a): writing libraries of code that can handle cobol based file-handling, file-storage.

                eg:perl module , python ...addon libraries.

                ability to leverage features of perl data-structures hashing , regular-expressions.               


Note: The above problem statement having been encountered in various scenarios
      and detailed in various 'Proof of concepts' as mentioned in 
      
       http://uk.geocities.com/ravivenkatus/projects.pdf
       http://ravishankarkv.tripod.com/projects.pdf
        ....apply appropriate
      'use-case' modeling, rationalize and arrive at a workable and feasible 
       solution both commercially and techinically viable.
