Mapping a Source File From a Source System To a Target System

Abstract

A method includes defining a file attribute indicator based on an attribute associated with a source file and based on a mapping policy. The source file has a source filename and the source file is migrated to a target system from a source system. The target filename is based on the source filename and the file attribute indicator. The target filename is used by a target application of the target system to process the source file. The target application is the source application configured for use on the target system.

1 . A method, comprising: 
 receiving a file attribute associated with a source file having a source filename, the source file being associated with a source system, the file attribute being used by a source application to process the source file; and    defining a target filename based on the source filename and an indicator of the file attribute, the indicator being used by a target application of a target system to process the source file at the target system, the target application being the source application configured for use on the target system.    
   
   
       2 . The method of  claim 1 , wherein the target filename includes a portion of the source filename, the defining includes incorporating an indicator of the file attribute into the target filename.  
   
   
       3 . The method of  claim 1 , wherein a file system of the source system is based on a non-hierarchical file system, a file system of the target system is based on a hierarchical file system, the source file being migrated from the source system to the target system.  
   
   
       4 . The method of  claim 1 , wherein the file attribute is determined by a source operating system of a source system.  
   
   
       5 . The method of  claim 1 , further comprising: 
 extracting at the target system the indicator from the target filename using a modified compiler library associated with the target application.    
   
   
       6 . The method of  claim 1 , wherein the file attribute is received at the target system and the target filename is defined at the target system.  
   
   
       7 . The method of  claim 1 , wherein the file attribute is received at the source system and the target filename is defined at the source system, 
 the method further comprising:    sending the target filename and corresponding source file to the target system.    
   
   
       8 . The method of  claim 1 , wherein the file attribute includes at least one of a record length, a file format, or a compression attribute.  
   
   
       9 . The method of  claim 1 , further comprising: 
 requesting at the target system the source file using at least a portion of the target filename; and    determining at the target system the file attribute associated with the source file based on the indicator.    
   
   
       10 . The method of  claim 1 , wherein a source data from the source file is processed by the target application using a modified compiler library, the source data being encoded in a source encoding, the source data having one or more portions encoded in the source encoding based on data type, the modified compiler library being configured to convert at least one portion of the source data into an encoding that can be manipulated by the target application.  
   
   
       11 . A method, comprising: 
 determining at a target system a file attribute associated with a source file based on an indicator of the file attribute included in a target filename, the source file being migrated to the target system from a source system, the target filename being defined based on a source filename associated with the source file and the file attribute; and    processing the source file at the target system using a target application based on the indicator of the file attribute, the target application being the source application configured for use on the target system.    
   
   
       12 . The method of  claim 11 , wherein the file attribute is determined by a source operating system of the source system.  
   
   
       13 . The method of  claim 11 , wherein the determining includes determining using a modified compiler library associated with the target application.  
   
   
       14 . The method of  claim 11 , wherein the determining includes determining based on a mapping policy.  
   
   
       15 . The method of  claim 11 , wherein a file system of the source system is based on a non-hierarchical file system, a file system of the target system is based on a hierarchical file system.  
   
   
       16 . The method of  claim 11 , wherein a source data from the source file is processed by the target application using a modified compiler library, the source data being encoded in a source encoding, the source data having one or more portions encoded in the source encoding based on data type, the modified compiler library being configured to convert at least one portion of the source data into an encoding that can be manipulated by the target application.  
   
   
       17 . A method, comprising: 
 defining a file attribute indicator based on an attribute associated with a source file and based on a mapping policy, the source file having a source filename, the source file being migrated to a target system from a source system; and    defining a target filename based on the source filename and the file attribute indicator, the target filename being used by a target application of the target system to process the source file, the target application being the source application configured for use on the target system.    
   
   
       18 . The method of  claim 17 , wherein the mapping policy is a user-defined policy, the user-defined policy is based on a syntax of the source filename.  
   
   
       19 . The method of  claim 17 , further comprising: 
 compressing the source file when a condition associated the mapping policy is satisfied; and    decompressing the source file based on the file attribute indicator when the source file is processed at the target system by the target application.    
   
   
       20 . The method of  claim 17 , wherein a file system of the source system is based on a non-hierarchical file system, a file system of the target system is based on a hierarchical file system.
