Conference Proceeding
Barclay, P. J., Fraser, C., & Kennedy, J. (1993)
Using a persistent system to construct a customised interface to an ecological db. In Interfaces to Database Systems: Proceedings of the First International Workshop on Interfaces to Database Systems (IDS92), Glasgow, 1-3 July 1992 (225-243
New applications of information technology have increasingly sophisticated user interface requirements. Such interfaces are sometimes highly application specific and therefore...
Regaining the conceptual level in object oriented modelling
Conference Proceeding
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 dat...
Modelling ecological data.
Conference Proceeding
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 ecol...
Implementation of the Prometheus Taxonomic Model: a comparison of database models and query languages and an introduction to the Prometheus Object-Oriented Model.
Journal Article
Raguenaud, C., Pullan, M. R., Watson, M. F., Kennedy, J., Newman, M. F., & Barclay, P. J. (2002)
Implementation of the Prometheus Taxonomic Model: a comparison of database models and query languages and an introduction to the Prometheus Object-Oriented Model. Taxon, 51(1), 131-142. https://doi.org/10.2307/1554970
Types of databases commonly used for handling taxonomic data are compared. It is shown that none of the existing types of databases fully support the requirements of taxonomic...

Using a metadata software layer in information systems integration.
Conference Proceeding
Roantree, M., Kennedy, J., & Barclay, P. J. (2001)
Using a metadata software layer in information systems integration. In Advanced systems engineering: CAiSE'01 - Software Engineering meets Information Systems Engineering (299-314). https://doi.org/10.1007/3-540-45341-5_20
A federated information system requires that multiple (often heterogenous) information systems are integrated to an extent that they can share data. This shared data often tak...

Working Paper
Raguenaud, C., Kennedy, J., & Barclay, P. J. A problem in querying recursive patterns with OQL)
Raguenaud, C., Kennedy, J., & Barclay, P. J. A problem in querying recursive patterns with OQL
This paper analyses the problem generated by recursive patterns in typed query languages such as OQL [Cattell '97]. Recursive patterns describe hierarchical structures such as...
