The language of KBMS1, kbProlog, is an extension of Prolog with modularization facilities, declarative update operations and persistence support. The implementation of the language has been realized in two steps: development of a translator from Obj U Datalog to U Datalog development of a ....

....of a meta interpreter computing in a bottom up style our rule language with update in rule bodies. Such meta interpreter has been realized on top of KBMS1 a Prolog extension developed at Hewlett Packard Laboratories in Bristol, providing modular program construction (through theory composition) [13]. The main feature of the U Datalog interpreter is a modular organization of the architecture, which results from the use of software engineering principles such as modular program development and composition. Such modular organization will be useful for several future extensions of U Datalog. The ....
