Abstract
Due to the development of the World Wide Web, the integration of
heterogeneous data sources has become a major concern of the
database community. Appropriate architectures and query languages
have been proposed. Yet, the problem of data conversion which is
essential for the development of mediators/wrappers architectures
has remained largely unexplored.
In this paper, we present the YAT system for data
conversion. This system provides tools for the specification and the
implementation of data conversions among heterogeneous data
sources. It relies on a middleware model, a declarative language, a
customization mechanism and a graphical interface.
The model is based on named trees with ordered and labeled nodes.
Like semistructured data models, it is simple enough to facilitate
the representation of any data. Its main originality is that it
allows to reason at various levels of representation. The YAT
conversion language (called YATL) is declarative, rule-based and
features enhanced pattern matching facilities and powerful
restructuring primitives. It allows to preserve or reconstruct the
order of collections. The customization mechanism relies on program
instantiations: an existing program may be instantiated into a more
specific one, and then easily modified. We also present the
architecture, implementation and practical use of the YAT prototype,
currently under evaluation within the OPAL project.
