Software refactoring

A computer-implemented method, comprising:

• associating a label to a program code unit of a software module to define a software module fragment;
• generating, using a plurality of software module fragments respectively associated with a plurality of different program code units, a module fragment list that defines the software module;
• receiving a request to retrieve the program code units from a data storage device;
• converting, based upon the received request and using labels associated with the program code units, the module fragment list into a list of physical locations, wherein
• the list of physical locations correspond to locations of the program code units within the data storage device.

A computer hardware system, comprising:

• a hardware processor configured to initiate the following executable operations:
• associating a label to a program code unit of a software module to define a software module fragment;
• generating, using a plurality of software module fragments respectively associated with a plurality of different program code units, a module fragment list that defines the software module;
• receiving a request to retrieve the program code units from a data storage device;
• converting, based upon the received request and using labels associated with the program code units, the module fragment list into a list of physical locations, wherein
• the list of physical locations correspond to locations of the program code units within the data storage device.

A computer program product, comprising:

• a computer-readable storage medium having stored thereon program code that, when executed by a computer hardware system, configures the computer hardware system to perform:
• associating a label to a program code unit of a software module to define a software module fragment;
• generating, using a plurality of software module fragments respectively associated with a plurality of different program code units, a module fragment list that defines the software module;
• receiving a request to retrieve the program code units from a data storage device;
• converting, based upon the received request and using labels associated with the program code units, the module fragment list into a list of physical locations, wherein
• the list of physical locations correspond to locations of the program code units within the data storage device.
