A conceptual language for querying object oriented data (1994)
Presentation / Conference Contribution
Barclay, P. J., & Kennedy, J. (1994, July). A conceptual language for querying object oriented data. Presented at 12th British National Conference on Database: Directions in Databases - BNCOD12, 1994

A variety of languages have been proposed for object oriented database systems in order to provide facilities for ad hoc querying. However, in order to model at the conceptual level, an object oriented schema definition language must itself provide f... Read More about A conceptual language for querying object oriented data.

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). Viewing objects. In M. Worboys, & A. F. Grundy (Eds.), Advances in databases: Proceedings of the 11th British National Conference on Database Systems (93-110). https://doi.org/10.1007/3-540-56921-9_6

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). 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..

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 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...
