Modelling ecological data. (1992)
Presentation / Conference Contribution
Barclay, P. J., & Kennedy, J. (1992). Modelling ecological data. In H. Hinterberger, & J. C. French (Eds.), Proceedings of the Sixth International Working Conference on Scientific and Statistical Database Management (77-93)

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). Regaining the conceptual level in object oriented modelling. In Proceedings of the 9th British National Conference on Databases, Aspects of Databases, (BNCOD 9) (269-305)

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 Generis knowledge base management system - an exploratory review. (1990)
Presentation / Conference Contribution
Kennedy, J., & Crerar, A. (1990). The Generis knowledge base management system - an exploratory review. In S. M. Deen, & G. P. Thomas (Eds.), Data and Knowledge Base Integration: Proceedings of the working conference on data and knowledge base integration

The information retrieval facilities of Generis, a knowledge base management system. (1989)
Presentation / Conference Contribution
Kennedy, J., & Crerar, A. (1989). The information retrieval facilities of Generis, a knowledge base management system. In Proceedings of the 11th BCS IRSG Research Colloquium on Information Retrieval (16-25)

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...

Query Language For Prometheus
Report
Raguenaud, C., Kennedy, J., & Barclay, P. J. Query Language For Prometheus. Napier University

This document presents the query language developed for the Prometheus database [RKB99]. This language is based on graphs and provides the user with a means to define the data to be extracted from the database and its manipulation. The language requi...

The Prometheus Database Model
Report
Raguenaud, C., Kennedy, J., & Barclay, P. The Prometheus Database Model. Napier University

This report presents the Prometheus database model. The model is designed to satisfy the requirements expressed in a previous document [RKB99]. The new model is based on a graph model and is extended with some mechanisms existing in other models (e.g... Read More about The Prometheus Database Model.

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.
