Interoperable Services for Federations of Database System (2002)
Presentation / Conference Contribution
Roantree, M., Kennedy, J., & Barclay, P. J. (2001, September). Interoperable Services for Federations of Database System. Presented at Fifth East-European Conference on Advances in Databases and Information Systems (ADBIS'2001)

The problems associated with defining interoperable protocols for heterogenous information systems has been the subject of researchers for many years. While numerous solutions have been offered, the problem remains unsolved, mainly due to the distinc... Read More about Interoperable Services for Federations of Database System.

A dual-level presentation model for developing user-interfaces. (2000)
Presentation / Conference Contribution
Barclay, P. J., & Kennedy, J. (2000, May). A dual-level presentation model for developing user-interfaces. Presented at ADVANCED VISUAL INTERFACES International Working Conference - AVI 2000

The visualisation of hierarchical information sets has been a staple of Information Visualisation since the field came into being in the early 1990’s. However, at present, support for visualising the correlations between multiple, overlapping sets of... Read More about A dual-level presentation model for developing user-interfaces..

Providing views and closure for the object data management group object model (1999)
Journal Article

The ODMG Object Model uses a standard for object-oriented database designers,
while attempting to address some issues of interoperability. This research is focused
on the viability of using the ODMG data model as a canonical data model in a
multid... Read More about Providing views and closure for the object data management group object model.

Using a conceptual data language to describe a database and its interface (1995)
Presentation / Conference Contribution
Mitchell, K., Kennedy, J., & Barclay, P. J. (1995, July). Using a conceptual data language to describe a database and its interface. Presented at 13th British National Conference on Database - BNCOD13, 1995, University of Manchester

We propose a conceptual approach to defining interfaces to databases which uses the features of a fully object oriented data language to specify interface objects combined with database objects. This achieves a uniform, natural way of describing data... Read More about Using a conceptual data language to describe a database and its interface.

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.

Viewing objects. (1993)
Presentation / Conference Contribution
Barclay, P. J., & Kennedy, J. (1993, July). Viewing objects. Presented at 11th British National Conference on Database System, Keele, UK

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..
