C3L+++: Implementing a Description Logics System on Top of an Object-Oriented Database System
نویسندگان
چکیده
This paper describes the Description Logics system C3L++ that is implemented on top of the object-oriented POET data base. The benefits of such an integration are the management of large size knowledge bases, an increased performance and data persistency. Moreover, it is planned to integrate the relational database MERLIN via an object-oriented access layer in C3L++ and test afterwards its performance.

متن کاملOn Attributes of Objects in Object-Oriented Software Analysis
One of the modern paradigms to develop a system is object oriented analysis and design. In this paradigm, there are several objects and each object plays some specific roles. There is a sequence of activities to develop an analysis model. In the first step, we work in developing an initial use case model. Then in the second step, they identify a number of concepts and build a glossary of partic...
