SURVEY AND PROPOSAL OF A METHOD FOR BUSINESS RULES IDENTIFICATION IN LEGACY SYSTEMS SOURCE CODE AND EXECUTION LOGS
Computer systems implement business processes from different organizations. Among the currently operating computer systems, much of it is classified as legacy system. Typically, legacy systems are complex applications that are still active, due to the high cost of modernization and a high degree of criticality. In recent years, were published several works addressing the importance of legacy systems modernization, emphasizing the extraction of the business process model implemented in these systems. Within this context, a key step is to extract knowledge from source code and / or systems execution logs, aiming to use this information in reverse engineering processes. In this work are presented and analyzed methods based on source code manipulation and systems execution logs mining, which can be used to extract knowledge from legacy systems, prioritizing business rules identification. A comparison between the two different approaches is presented, as well as their positive and negative characteristics. Our results include a list of desired features and a proposal of a method for legacy systems reverse engineering and business rules identification.
