| Summary: | 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.
