Full Description
This volume is the proceedings of the Second International
Conference on Deductive and Object-Oriented Databases
(DOOD). During the last decade, deductive and
object-oriented systems have received a great deal of
attention, but for the most part these two fields were
evolving independently of each other. Today there is a large
body of work suggesting that the deductive and
object-oriented paradigms complement each other.
The object-oriented paradigm is characterized by its view of
the data, whereby information is grouped around objects with
complex internal structure accessed via methods. The
declarative paradigm is centered around the idea that data
manipulation must be done through a declarative, logic-based
language. It is hoped that these two aspects, brought
together in one system, will provide an integrated framework
fora new database technology.
The DOOD conference brings together researchers and
developers in the fields of deductive and object-oriented
databases to stimulate technical discussion and accelerate
the integration of the two technologies. This volume
contains 28 contributed papers (selected from 98
submissions) and two invited papers by world-renowned
researchers.
