A computer code generation tool generates computer code to facilitate development of call detail record (CDR) management tools. The computer code generation tool inputs one or more raw CDR structures and creates a generic CDR structure therefrom. Given a generic CDR structure and one or more raw CDR structures that it encapsulates, the computer code generation tool generates computer code to read data from the raw CDR(s) stored on disk and store that data in the generic CDR. The computer code generation tool can also generate computer code to generate raw CDRs from the data stored in the generic CDR.
