Research Interests

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.

Selected Awards and Honors:

2013 George C. Hoffman Award for Faculty Excellence, Portland State University. 
The Hoffmann Award is given annually to a faculty member in a tenure-track or tenured appointment in recognition of distinguished contributions to the University in the areas of instruction, university service, and scholarship (in that order) which are done in the spirit of humanism, civility, and collegiality with particular dedication to students and loyalty to the University—values especially cherished by George Hoffmann.

 

James Terwilliger, my PhD student at the  time, was selected as the outstanding graduate student in MCECS and also the outstanding graduate student at PSU.  The awards were given just before graduation, June 2009.
