Abstract:
In industrial informatics, there exists a requirement
to model and design views at a higher level of abstraction.
Since the classical view definitions are only available
at the query or instance level, modelling and maintaining
such views for complex Enterprise Information Systems (EIS)
is a challenging task. Further, the introduction of semistructured
data (namely XML) and its rapid adaptation by
the commercial and industrial systems increased the complexity
for view design and specification. To address such and issue,
in this paper we present; (a) a layered view model for
XML, (b) a design methodology for such views and (c) some
real-world industrial applications of the view model. The
XML view formalism is defined at the conceptual level and
the design methodology is based on the XML Semantic (XSemantic)
nets, a high-level Object-Oriented (OO) modelling
language for XML domains.
