Interactive migration of legacy databases to net-centric technologies

Due to the rapid growth of e-commerce (and other Internet-related technologies), many companies want to migrate their information systems to the net-centric environment. We are proposing a toolkit (Varlet/Babel) that helps the user to achieve this goal. This is accomplished in two stages. In the first stage, a database schema is obtained and refined, then an XML description for the database schema is generated and used to wrap access to the information system. In this paper, we focus on the second stage and describe the methods that are used to create a mapping between the generated schema and a standard (interchange) schema and to make a second wrapper around the information system.
