A conceptual language for querying object oriented data. In D. S. Bowers (Ed.), Directions in Databases: Proceedings [of the] 12th British National Conference on Databases, BNCOD 12, Guildford, United Kingdom, July 6-8, 1994 (187-204). https://doi.org/10.1007/3-540-58235-5_43
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...
Viewing objects.
Conference Proceeding
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 vie...
Using a persistent system to construct a customised interface to an ecological db.
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...
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...
Semantic integrity for persistent objects
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...
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...
