Reengineering offers an approach to migrate a legacy system towards an evolvable system in disciplined manners. Software reverse engineering is the process of analyzing the components and component interrelationships of a software system in order to describe that system at a level of abstraction higher than that of the original system. Reengineering is the process of examination, understanding, and alteration of a system with the intent of implementing the system in a new form. Software reengineering is considered to be a better solution for handling legacy code when compared to re-developing software from the original requirements. This final project presents a case study that illustrates how a combination of object-oriented (OO) and procedural techniques can be used in tandem to reengineer an existing application (in this case the e-Procedure software of State Batam Polytechnic). And to further prove which part of the procedural system can be reused in the new object oriented system.idTeknik InformatikaInformatikaComputer Sciences, Knowledge, SystemsThesis
