Database Data Models Lois
Delcambre has worked on object-oriented and other database data models with
an emphasis on the structural aspects of the model. The database structure
reflected in the class hierarchy is semantically much richer than traditional
database models. Her work in this area (with S. Urban) includes constraint
analysis to generate algorithmically and process the set of constraints
implied by the application schema, plus additional application constraints
expressed in a constraint language. This analysis assists the application
designer with constraint formulation, schema design and transaction design.
Further work in this area (with B. Lim) has led to the characterization of
constraints appropriate for constraint analysis, termed object-centered
constraints, and has considered the use of the basic algorithm for constraint
enforcement. Work on the
class construction primitives in a semantic data model (with K. Davis) has
led to the development of the Class Model and the associated Class Algebra, a
closed, class-forming algebra that includes the object-oriented equivalent of
the relational algebra operations. One of the contributions of this work is a
set of sound and complete rules of inference for inferring structural
relationships in an application schema. The Classifier identifies all
structurally inconsistent classes and all isa
relationships implied by the current schema. More recent
work (with S. Bowers) has resulted in the definition of the Uni-level description (ULD), a uniform, generic
representation for a wide range of structural models that can accommodate
multiple levels of schema and missing schemas. The ULD permits the use
of powerful transformation rules and navigation capabilities across a range
of data models. Lois
Delcambre has also been exploring models for terms or keywords that are used in a digital library (with M. Weaver). The
Metadata++ model includes broader/narrower term, synonym, and general
association relationships but differs from classical thesarus
in that there is no notion of preferred term and terms are
allowed to participate in multiple locations in the broader/narrower
term hierarchy. |
