OTHY: object to HY permedia

摘要

In this paper, we present a Web-based universer for browser for hetero-gereous and non federated databases. Recently appeared bypermedia methods are at the core of this system. However, contrary to these methodologies, our tool directly supports the conception, the navigation, and the presentation phases without requiring any modification of the databases. It is mostly based on the OTHY framework, which is a library of classes to develop different kinds of presentation based on well-established hypertext concepts. The design of our tool and a first implementation resulted in a prototype under the O_2 OODBMS. This implementation was convincing. Consequently, a Java deveopment and two querying and relational database retro-engineering modules are on the path to be added to this prototype.
