....not produce any value. In our case, the definition is enough for overriding to take place and the success or failure of the execution does not a#ect the overriding. This choice also has serious conceptual and implementation e#ciency related consequences that we discuss at length in [11] and in [10]. 5 Notice that the choice of the negation semantics in Datalog neg does not a#ect the semantics of Datalog programs. 127 other languages, our syntax is also much more flexible that allows the users to model their universe of discourse in an object oriented way as opposed to relational ....

....is then evaluated and the answers are returned to the users. We do not include a discussion on the architecture of the Datalog System in this paper for the want of space. However, a complete discussion on the Datalog System, its architecture and implementation techniques may be found in [10]. 7 Conclusion and Future Works Our work can be extended in several di#erent ways. It seems appropriate for some applications to have a choice to override methods dynamically or statically based on the need of the application. For some applications, a method may call for monotonic inheritance ....
