Financial industry is very important in IT industry. Modern financial industry is knowledge-oriented industry. Based on the foundation of knowledge and information, the managerial character plays a more and more role in organization structure, operation mode, and business exploit. Information accelerates the development innovation, and managerial of financial industry. For financial industry depends on information technology, it requires that financial information system has the character of high speed, stable, secure ability of information dealing, and integration with new business.For financial industry is the industry of using IT technology very early, the legacy financial systems occupy large proportion of software legacy system. The histories of these legacy systems are very long. These systems have lots of issues (e.g.: bottleneck of performance, the outdated design and technology, new functions integration of business requirement). It imminently need refactor these systems with new technology, software design idea and software engineering method to satisfy the need of system.Software Reengineering is engineering method to evolve legacy system;it includes Reverse Engineering, Forward Engineering and Transformation. PE system in a international finance service corporation is a classical legacy system.This article is trying to research the Reengineering theory and developing status, analyse a universal reengineering model. During the process to PE legacy system reengineering, we practice and use the reengineering theory and model。 This article introduces the process of reengineering to parts of the modules of whole system and tries to figure out a way that fits the actual situation. This is development and reinforce to the universal model.During reverse engineering, we firstly abstract use case, then analyse source code. Based on these work, we can abstract business rule though we are not familiar with the business logic.At the same time, we discuss and analyse some difficulty during the whole processand the points of future work.
