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...

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...

Integrating View Schemata Using an Extended Object Definition Language

Conference Proceeding
Roantree, M., Kennedy, J. B., & Barclay, P. J. (2001)
Integrating View Schemata Using an Extended Object Definition Language. In C. Batini, F. Giunchiglia, P. Giorgini, & M. Mecella (Eds.), Cooperative Information Systems; Lecture Notes in Computer Science (150-163). https://doi.org/10.1007/3-540-44751-2_13
View mechanisms play an important role in restructuring data for users, while maintaining the integrity and autonomy for the underlying database schema. Although far more comp...

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...
