Welcome to BalticDB & IS'2000!
As Organising Chair of the BalticDB&IS'2000 I have a
pleasure in welcoming you to Vilnius at the Fourth IEEE
International Baltic Workshop on Databases and Information
Systems.
The Workshop is organised by the Vilnius Gediminas
Technical
University,
Institute
of
Mathematics
and
Informatics, and Lithuanian Computer Society in cooperation
with Vilnius University, Vytautas Magnus University, Kaunas
University of Technology, Klaipeda University, Law Academy
of Lithuania, and Department of Information and Informatics
(Ministry of Public Administration, Reforms and Local
Authorities). The Workshop is approved by the IEEE
Communication Society for Technical Co-Sponsorship.
The aim of the Baltic Workshop is to provide a forum
for the exchange of scientific achievements between the research
communities of Baltic countries and the rest of the world in the
area of databases and information systems. The objective of the
workshop is to bring together researchers, practitioners, and
doctoral students and to give the opportunity to present their
work and to exchange their ideas. The Workshop programme
includes 7 regular sessions. It is preceded by one-day Doctoral
Consortium chaired by invited professors, and two tutorials
given by leading researchers. Other Satellite Events are
Professional Forum, and Panel Discussion on the Potential of
Quality Information Systems for Eastern European Economic,
Technologic, and Managerial Leverage. The aim of the
Professional Forum is to share the practical experience and
discuss actual problems in the area of Information Systems and
Information Technologies. Especial attention is paid to these
problems in the Baltic Sea region.
I express the hope that your discussions at the
Workshop will prove fruitful and will contribute to the
successful solution of the significant problems in the
information systems and database area. I wish you also a very
pleasant time during your staying in Lithuania. Social events
will emphasise the regional atmosphere. I hope that one of the
results of this Workshop will be your further visiting to our
country, where you will always be welcome.

TUTORIALS
TUTORIAL I
SYSTEMATIC APPROACHES TO SOFTWARE
REUSE
Ronald J. Leach (USA)
About the instructor
Dr. Ronald J. Leach is currently a full professor at the
Department of Systems & Computer Science at Howard
University, USA. His research interests are Software
engineering,
especially software
reuse,
software
measurement and metrics, software fault-tolerance. Dr. R. J.
Leach is author of five books. He is technical manager for
Software Technology Area of HUFAST project in software
fault-tolerance, partially supported by U.S. Air Force Office
of Scientific Research. He is working also in the project
“Cost modelling of reuse-based software engineering
processes”, partially funded by NASA at the Goddard Space
Flight Center. He is a member of the College of Engineering,
Architecture and Computer Sciences.
E-mail address: [email protected]
OBJECTIVES OF TUTORIAL I
This introductory tutorial is intended for those who wish to
have an overview of some of the issues involved with developing a systematic approach to software reuse. Software
reuse has the potential for both improving the quality of
software systems and simultaneously reducing their cost.
This tutorial will present some approaches that have been
shown to be successful and will also provide a set of pitfalls
to be avoided when attempting to improve software
productivity by employing software reuse.

Gerd Wagner (Germany)
About the instructor
Dr. Gerd Wagner is currently a research scientist in the
Computer Science Department at the Free University of
Berlin. He received an MSc in mathematics and a PhD in
philosophy from the Free University of Berlin, and a
German Habilitation degree in computer science from the
University of Leipzig. He was visiting researcher at the
Institute de Recherche en Informatique de Toulouse in 1994
and at Universidade Nova de Lisboa in 1995. His research
interests are focused on the foundations of information and
knowledge systems and of multi-agent systems. Dr. Wagner
is the guest editor of a 1997 special issue of the Journal of
Applied Non-classical Logic on "Handling Inconsistency in
Knowledge Systems", and the author of the book
"Foundations of Knowledge Systems with Applications to
Databases and Agents" (Kluwer Academic Publishers,
1998). In 1999, he initiated and co-organised the first
International Workshop on Agent-Oriented Information
Systems (http://www.AOIS.org). In recent years, Dr.
Wagner has also worked with the enterprise resource
planning system Baan IV. He has been involved in several
Baan IV customisation projects, and has taught "Baan IV
Tools" to programmers and consultants.
OBJECTIVES OF THE TUTORIAL II
Enterprise resource planning (ERP) systems are generic and
comprehensive business software systems based on a distributed computing platform including one or more database
management systems. They combine a global enterprise
information system covering large parts of the information
needs of an enterprise with a large number of application
programs implementing all kinds of business processes that
are vital for the operation of an enterprise. These systems
help organizations to deal with basic business functions such
as purchase /sales /inventory ('distribution') management,
financial accounting and controlling, and human resources
management, as well as with advanced business functions
such as project management, production planning, supply
chain management, and sales force automation.
First generation ERP systems now run the complete back
office functions of the worlds largest corporations. The ERP
market rose at 50% per year to $8.6 billion in 1998 with
22,000 installations of the market leader, SAP R/3. The
benefits of a properly implemented ERP system can be
significant. Inventory costs can be reduced (on the average)
by 25 to 30%; raw material costs can be reduced by about
15% on average. It is estimated that businesses around the
world are now spending $10 billion per year on ERP
systems, and will be over $50 billion per year by 2003.
Typically, ERP systems provide multi-instance database
management as well as configuration and version (or
'customisation') management for the underlying database
schema, the user interface, and the numerous application
programs associated with them. The sheer size and the
tremendous complexity of these systems make them difficult
to deploy and maintain. Despite the world-wide success of
systems like SAP R/3 and Baan IV, the underlying
architectures, data models, transaction mechanisms and
programming techniques are to a large degree unknown to
computer scientists.
The goal of this tutorial is to present the information technology of Baan IV, as a representative of the ERP system
paradigm, from a computer science (rather than from a business management) perspective, relating it to established
database and distributed systems concepts and techniques. A
critical assessment of Baan IV will point out some of its
merits and weaknesses. The tutorial will help attendees to
understand the potential of ERP system technology in
general, and of Baan IV ERP system technology in
particular, and how it relates to their own research and
development work
LOCATION
The BalticDB&IS'2000 will be held at the Vilnius
Gediminas Technical University (Sauletekio aleja, 11),
located about 5 km. from the downtown Vilnius.
You may use trolley bus number 2 or 19 and exit at the Studentu stop. From downtown you may use also trolley bus
number 3, 4, 10, 11, exit at the final station and use trolley
bus number 2 or 19.
A taxi from the Airport to Vilnius Gediminas Technical University generally costs about 30 Lt (about 8 USD), and from
Airport to downtown Vilnius about 15 Lt (4 USD). Your
may use also bus number 2 and exit in the downtown (e.g. at
the Lukishkiu stop).
