Preface
This volume contains the papers which were presented at the Second
International Conference on Object Oriented Information Systems
00IS'9.5 which was held at Dublin City University, 18-20 December 199.5.
A total of 60 papers from 20 countries were submitted in response to
our call for papers. The refereeing process involved each paper being
refereed by at least two referees from our international Programme
Committee. Altogether, 30 papers were finally selected for inclusion in the
conference proceedings.
The papers included in the proceedings address a wide range of issues
relating to object-oriented technology, theory and software development
practice. Four papers were selected on software reuse and these examine
object reuse and its limitations from a variety of perspectives. Berrisford
looks at the difficulties of designing class hierarchies in the face of real
world fuzziness. Three papers were accepted on Object Oriented Models
and these address important questions for modelling in a range of
applications. Ba"ett and Tangney introduce a new model and language
which addresses the limitations in terms of language support for
computer supported cooperative work. Five papers were accepted for the
Formal Aspects/Implementation stream. Higgins specifies a denotational
definition of a functional object-oriented language and shows how this
can be of value for object-oriented query optimisation.
There were two sessions on Object-Oriented DBMS looking at
distributed aspects of OODBMS, active OODBMS, data warehousing and
temporal data management to mention a few of the topics. The session on
Object-Oriented Applications looked at spatial and multimedia issues in
00 applications. The session on software tools focused on tools for reuse,
integration and migration strategies. Measurement and methods were
addressed in the Metrics and Methods Session.
Acknowledgements
The organisation of this conference involved a great deal of hard work by
a small team of people. I would like to express our deepest gratitude to
our colleagues at South Bank University in the UK, particularly Dilip
Patel, Shushma Patel, Yuan Sun and Terry Bayliss. I thank Jane Grimson,
my co-chair on the Programme Committee for all her efforts,
encouragement and hard work. To the Programme Committee who
worked so hard to ensure that the papers were refereed in good time,
sincerest thanks. Our special thanks to Keith Jeffery for his advice and
guidance and support
vi
Nearer to home, I am most grateful for the continuing encouragement
of Michael Ryan, Head of the School of Computer Applications at DCU.
The members of the Local Organising Committee deserve the highest
praise for their efforts throughout the last year to ensure the success of the
conference.
Special mention must go the Brian Stone for the many (voluntary) late
nights and weekends he worked with me to ensure that our plans stayed
on track. Among other duties Brian acted as co-editor, organised and
chaired the Industry Day and performed the duties of Local Organising
Committee co-chair. It is no exaggeration to say that the conference
succeeded in a large part due to Brian's commitment and dedication. To
Mark Roantree, David Sinclair (treasurer), Pierce Hickey, John Cardiff
and Larry McNutt many thanks for their tireless efforts.
Our main sponsors, lona Technologies Ltd. and mM (Ireland) Ltd.,
together with our associate sponsors Broadcom Eireann Research Ltd and
The Centre for Software Engineering, are owed a debt of gratitude for
their significant and important support for the conference.
Finally, we thank Springer-Verlag, our publishers for their support in
producing the proceedings.
