Mainframe Application Reverse Engineering: Key to Unlocking Your Business Content

Abstract

The audience of this paper is CIOs who are contemplating reducing operational cost of mainframes and supporting the business objectives of their enterprise via a modernization strategy that calls for reverse engineering. The paper examines the main drivers of reverse engineering by organizations that have decided to continue using mainframes and highlights key features of the reverse engineering service from HCL.

Excerpts from the Paper
The process of reverse engineering allows architects to study, analyze and document the internal workings of a software system. It also allows them to examine the application’s business functionality and technical characteristics such as security, interoperability, and other aspects with the aim of determining the make up of its original design. Following a detailed study of the underlying operational services such as transaction processing, mainframe batch processing, spooling, database and file management system, engineers prepare a detailed specifications document of the functionality provided by the current application.

This document is the output of the reverse engineering process and can be used for application development, support and maintenance, effective capturing of requirements, and for architecting code reuse or change, or for system integration. The specifications document can also be used as inputs for forward engineering or as a reference document during the implementation phase.
