A framework for user-interfaces to databases (1996)
Presentation / Conference Contribution
Mitchell, K., Kennedy, J., & Barclay, P. J. (1996). A framework for user-interfaces to databases. In T. Catarci, M. F. Costabile, S. Levialdi, & G. Santucci (Eds.), Proceedings [of the] 3rd International Workshop on Advanced Visual Interfaces, AVI'96 (81

A framework for user-interfaces to databases (IDSs) is proposed which draws from existing research on human computer interaction (HCI) and database systems. The framework is described in terms of a classification of the characteristic components of a... Read More about A framework for user-interfaces to databases.

3D information visualisation: Identifying and measuring success (1995)
Presentation / Conference Contribution
Kennedy, J., Mitchell, K., Barclay, P., & Marshall, B. (1995). 3D information visualisation: Identifying and measuring success. In Proceedings of the 2nd International FADIVA Workshop, 1995

This paper presents some of our views on information visualisation and interfaces to databases with respect to the theme of the workshop.

Using a conceptual data language to describe a database and its interface (1995)
Presentation / Conference Contribution
Mitchell, K., Kennedy, J., & Barclay, P. J. (1995). Using a conceptual data language to describe a database and its interface. In C. Goble, & J. Keane (Eds.), Advances in Databases: Proceedings [of the] 13th British National Conference on Database - BNCOD

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.

Interfaces to data models: taking a step backwards (1995)
Presentation / Conference Contribution
Barclay, P., Crerar, A., & Davidson, K. (1995). Interfaces to data models: taking a step backwards. In Interfaces to Database Systems (IDS94) Proceedings of the Second International Workshop on Interfaces to Database Systems, Lancaster University, 13–1

This paper is concerned with data modelling and the question of how to improve the quality of software tools to provide more effective support for the modeller. With the increasing interest in building intelligent interfaces to databases and associat... Read More about Interfaces to data models: taking a step backwards.

A conceptual language for querying object oriented data (1994)
Presentation / Conference Contribution
Barclay, P. J., & Kennedy, J. (1994). 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-

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 genetic algorithm for optimizing fixed polarity Reed-Muller expansions of boolean functions (1994)
Journal Article
Millert, J. F., Luchian, H., Bradbeeru, P. V. G., & Barclay, P. J. (1994). Using a genetic algorithm for optimizing fixed polarity Reed-Muller expansions of boolean functions. International Journal of Electronics, 76(4), 601-609. https://doi.org/10.1080/0

The use of a genetic algorithm is presented which determines good sub-optimum fixed polarity Reed-Muller expansions of completely specified boolean functions. The algorithm performs better than previous techniques which find a good fixed polarity by...

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..

Using a persistent system to construct a customised interface to an ecological db. (1993)
Presentation / Conference Contribution
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 (IDS

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...

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..
