Control of a large massively parallel database machine using SQL catalogue extensions, and a DSDL in preference to an operating system (1992)
Presentation / Conference Contribution
Unwalla, M., & Kerridge, J. (1992, July). Control of a large massively parallel database machine using SQL catalogue extensions, and a DSDL in preference to an operating system. Presented at Advanced Database Systems: 10th British National Conference on Databases, BNCOD 10, Aberdeen, Scotland

The IDIOMS parallel database machine supports large applications where integrated OLTP and MIS is required. It can be considered a relational engine, and SQL is used as the MIS query language. We make some comparisons between IDIOMS and other databas...

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.
