A New DBMS Architecture for DB-IR Integration
Director of Advanced Information Technology Research
Korea Advanced Institute of Science and Technology
Nowadays, there is an increasing need to integrate the DBMS
(for structured data) with Information Retrieval (IR) features (for
unstructured data). DB-IR integration becomes one of major challenges
in the database area. Extensible architectures provided by commercial
ORDBMS vendors can be used for DB-IR integration. Here, extensions
are implemented using a high-level (typically, SQL-level) interface.
We call this architecture loose-coupling. The advantage of
loose-coupling is that it is easy to implement. But, it is not preferable
for implementing new data types and operations in large databases
when high performance is required. In this talk, we present a new
DBMS architecture applicable to DB-IR integration, which we call
tight-coupling. In tight-coupling, new data types and operations
are integrated into the core of the DBMS engine in the extensible
type layer. Thus, they are incorporated as the "first-class
citizens" within the DBMS architecture and are supported in
a consistent manner with high performance. This tight-coupling architecture
is being used to incorporate IR features and spatial database features
into the Odysseus ORDBMS that has been under development at KAIST/AITrc
for over 16 years. In this talk, we introduce Odysseus and explain
its tightly-coupled IR features (U.S. patented in 2002). Then, we
demonstrate excellence of tight-coupling by showing benchmark results.
We have built a web search engine that is capable of managing 20~100
million web pages in a non-parallel configuration using Odysseus.
This engine has been successfully tested in many commercial environments.
In a parallel configuration, it is capable of managing billons of
web pages. This work won the Best Demonstration Award from the IEEE
ICDE conference held in Tokyo, Japan in April 2005.
Whang is Professor of Computer Science and Director of Advanced
Information Technology Research Center (AITrc) at KAIST. Previously,
he was with IBM T.J.Watson Research Center from 1983 to 1990.
Since joining KAIST in 1990, he has been leading the Odysseus
DBMS project featuring tight-coupling of DBMS with information
retrieval (IR) and spatial functions. Dr. Whang is one of the
pioneers of probabilistic counting, which nowadays is being widely
used in approximate query answering, sampling, and data streaming.
One of the algorithms he co-developed at IBM Almaden (then San
Jose) Research Lab in 1981 has been made part of DB2. Dr. Whang
is the author of the first main-memory relational query optimization
model developed in 1985 and reported in 1990 in ACM TODS in the
context of Office-by-Example (OBE). This model influenced subsequent
optimization models of commercial main-memory DBMSs. His research
has covered a wide range of database issues including physical
database design, query optimization, DBMS engine technologies,
and more recently, IR, spatial databases, data mining, and XML.
Dr. Whang is a Co-Editor-in-Chief of the VLDB Journal, having
served the journal for 17 years from its inception as its founding
editorial board member. He is a Trustee Emeritus of the VLDB Endowment
and served the international academic community as the General
Chair of VLDB2006, DASFAA2004, and PAKDD2003, as a PC Co-Chair
of VLDB2000, CoopIS1998, and ICDE2006, and as an editorial board
member of journals such as IEEE TKDE and IEEE Data Engineering
Bulletin. He served as an IEEE Distinguished Visitor from 1989
to 1990. He earned his Ph.D. from Stanford University in 1984.
Dr. Whang is an IEEE Fellow, a member of the ACM and IFIP WG 2.6.

The Evolution of Digital Evidence as a Forensic Science
Dr. Marc Rogers
Chair of the Cyber Forensics Program
Department of Computer and Information Technology
Purdue University, USA
field of Digital Evidence while garnering significant
attention by academia, the public, and the media,
has really just begun its journey as a forensic science.
Digital Forensic Science (DFS) in general is an immature
discipline in comparison to the other more traditional
forensic sciences such as latent fingerprint analysis.
Digital Evidence, which falls under the larger umbrella
of DFS, truly encompasses the notion of being an applied
multi-disciplinary science. The areas of Computer
Science, Technology, Engineering, Mathematics, Law,
Sociology, Psychology, Criminal Justice etc. all have
played and will continue to play a very large role
in maturing and defining this scientific field. The
presentation will look at the history of Digital Forensic
Science and Digital Evidence, the current state of
the field, and what might be in store for the future.
Marc Rogers, Ph.D., CISSP, CCCI is the Chair of the
Cyber Forensics Program in the Dept. of Computer and
Information Technology at Purdue University. He is an
Associate Professor and also a research faculty member
at the Center for Education and Research in Information
Assurance and Security (CERIAS). Dr. Rogers was a senior
instructor for (ISC)2, the international body that certifies
information system security professionals (CISSP), is
a member of the quality assurance board for (ISC)2's
SCCP designation, and is the International Chair of
the Law, Compliance and Investigation Domain of the
Common Body of Knowledge (CBK) committee. He is a former
police detective who worked in the area of fraud and
computer crime investigations. Dr. Rogers is the associate
editor of the Journal of Digital Forensic Practice and
co-editor of the Journal of Digital Forensics Security
and Law, and sits on the editorial board for several
other professional journals. He is also a member of
various national and international committees focusing
on digital forensic science and digital evidence. Dr.
Rogers is the author of numerous book chapters, and
journal publications in the field of digital forensics
and applied psychological analysis. His research interests
include applied cyber forensics, psychological digital
crime scene analysis, and cyber terrorism.
