碩士 === 國立交通大學 === 資訊管理研究所 === 81 === When converting traditional file systems to data base environment, it often requires much information about data entities, their definitions and inter-relationships, etc. Usually, such information is hidden in piles of source programs and system documents. Ideally, the information should be reused to help database design. This research describes a data reengineering process to get useful infomation from traditional file systems. This process includes three software tools : (1)data reverse engineering tool that extracts information, (2) data re- engineering tool that clears up data naming problems, and (3) data dictionary tool that stores all relevant infor- mation. This process then extends to data maintenance for constant evolution. The compelete process provides an effective transition from traditional file systems to data base environment.
