Using a persistent system to construct a customised interface to an ecological db. (1993)
Presentation / Conference Contribution
Barclay, P. J., Fraser, C., & Kennedy, J. (1992, July). Using a persistent system to construct a customised interface to an ecological db. Presented at 1st International workshop on Interfaces to Database

New applications of information technology have increasingly sophisticated user interface requirements. Such interfaces are sometimes highly application specific and therefore require to be customised to the given application area. Technology is requ...

Viewing objects. (1993)
Presentation / Conference Contribution
Barclay, P. J., & Kennedy, J. (1993, July). Viewing objects. Presented at 11th British National Conference on Database System, Keele, UK

This paper examines the incorporation of database views into an object oriented conceptual model. An approach is presented where views are themselves objects, instances of view classes. These view objects provide new ways of interacting with preexist... Read More about Viewing objects..

Modelling ecological data. (1992)
Presentation / Conference Contribution
Barclay, P. J., & Kennedy, J. (1992, June). Modelling ecological data. Presented at 6th International Workshop on Scientific and Statistical Database Management, 1992

Ecological surveys generate large quantities of data; database technology has not yet reached its full
potential in this area. Here we investigate approaches to modelling ecological data, considering the require-
ments for a successful model. An ob... Read More about Modelling ecological data..

Semantic integrity for persistent objects (1992)
Journal Article
Barclay, P. J., & Kennedy, J. (1992). Semantic integrity for persistent objects. Information and Software Technology, 34(8), 533-541. https://doi.org/10.1016/0950-5849%2892%2990147-H

Modelling constructs for specifying semantic integrity are reviewed, and their implicit execution semantics discussed. An integrity maintenance model based on these constructs is presented. An implementation of this model in a persistent programming... Read More about Semantic integrity for persistent objects.

Regaining the conceptual level in object oriented modelling (1991)
Presentation / Conference Contribution
Barclay, P. J., & Kennedy, J. (1991, July). Regaining the conceptual level in object oriented modelling. Presented at 9th British National Conference on Database - BNCOD9, 1991

This paper attempts to develop a conceptual model for the object oriented description of data. We abstract from various logical model features essential for thinking about data in an object oriented framework. These features are presented through exa...

The information retrieval facilities of Generis, a knowledge base management system. (1989)
Presentation / Conference Contribution
Kennedy, J., & Crerar, A. (1989, April). The information retrieval facilities of Generis, a knowledge base management system. Presented at 11th Information Retrieval Research Colloquium, 1989

The authors have been working closely with Deductive Systems Ltd. (DSL) in beta testing Generis, a new KBMS product. The paper focuses on Generis' document management facilities which offer a potentially powerful mechanism for automatic indexing, key...

Database support for taxonomy
Report
Raguenaud, C., Kennedy, J., & Barclay, P. J. (1999). Database support for taxonomy. Napier University

Taxonomists classify the organisms they study in order to refer to, identify and understand them. However, the same organism may at times be classified according to different taxonomic opinions and subsequently have several alternative names or be pl... Read More about Database support for taxonomy.
