Schema updates on shared object-oriented databases (OODBs) are almost always prohibited because of the risk of making existing application programs obsolete when run against the modiied schema. We have proposed a solution approach, called Transparent Schema Evolution (TSE), that successfully addresses this problem by integrating schema evolution capabilities with object-oriented view facilities...

Fleming, MD, Green Templeton College, University of Oxford, 43 Woodstock Rd, Oxford OX2 6HG, United Kingdom; e-mail: kenneth.fleming@ medsci.ox.ac.uk. The burden of cancer is on the rise. More than 7 million people per year die as a result of cancer, and it is responsible for more deaths worldwide than AIDS, malaria, ...

The goal of this mini-project was to explore the literature on computer-assisted whiteboards as Augmented Reality (AR) devices and to investigate the possible use of Kimura to assist in Software Engineering tasks. Kimura is “an augmented office environment to support common multitasking practices. Previous systems, such as Rooms, limit users by constraining the interaction to the desktop monito...

In this paper, I describe how collaborative problem formulation can be facilitated by the language used to describe the problem and by a tool that eases use of that language. The situations that constitute urban design problems are extremely complex, and formulating these problems is usually an intractable task. As a procedurally rational response to this intractability, scholars and practition...

A new method for providing integrated support for multiple development notations (including analysis, design, and implementation) within Information Systems Engineering Environments (ISEEs) is described. Our method supports both static integration of multiple notations and the implementation of dynamic support for them within an integrated ISEE. First, conceptual data models of different analys...

Supporting large amounts of spatial data is a significant characteristic of modern databases. However, unlike some mature relational databases, such as Oracle and PostgreSQL, most of current burgeoning NoSQL databases are not well designed for storing geospatial data, which is becoming increasingly important in various fields. In this paper, we propose a novel method to provide R-tree index, as...

Relational database systems do not e ectively support complex queries containing quanti ers (quanti ed queries) that are increasingly becoming important in decision support applications. Generalized quanti ers provide an e ective way of expressing such queries naturally. In this paper, we consider the problem of processing quanti ed queries within the generalized quanti er framework. We demonst...

Abstract. Semantic Web technologies facilitate tasks such as collaboration, shared experimentation, and annotation of resources and have particular strength in capturing qualitative scientific arguments. In this paper we explore the design of an ontology for a social simulation tool called FEARLUS-G. This lead to a description of the tools used during the ontology engineering, and how the ontol...
