Title:
Databases and the Web: An Oxymoron or a Pleonasm
-
Speaker:
Yannis E. Ioannidis, University of Athens
-
Abstract:
Several researchers claim that the web is just a big database and that
extending database technology to the new environment will solve all problems.
Several other researchers claim that databases are just a special case
of the web and that specializing web technology to the specific database
environment will solve all problems. In this talk, we will discuss
some of the arguments used by the two camps and then examine how the two
technologies stand up against several important technical questions.

Title:
Time for Change: Why Not Transact In Memory?
-
Speaker:
Sang K. Cha, Seoul National University
-
Abstract:
The last decade has seen significant changes in the hardware technology.
Today, microprocessors run at the speed of GHz, and computer systems using
multiples of such high-speed CPUs are quite common in the market. On the
memory side, as the price of DRAM chips continues to drop, a few GB of
memory is easily affordable in today's computer systems, and soon this
affordable memory size will grow to a few tens of GB, and eventually is
expected to reach a terabyte during the coming decade.
Despite the rapid changes in hardware, the changes in the data management
software occur slowly, primarily because the commercial DBMS vendors are
heavily invested in the disk-primary database architecture. While this
disk-primary architecture can benefit from large memory as well using it
as the buffer for the disk-resident data blocks, the performance gain is
inherently limited by the indirect nature of data access and many disk-primary
design decisions.
The Main-Memory DBMS assumes that the database resides primarily in
memory. This memory-primary architecture, free from the overhead of mapping
between memory and disk, has many advantages over the disk-primary architecture
such as better focus on the utilization of CPU power and IO channel capacity,
and the ease of tuning the system. This talk reviews the current state
of main memory database research and shows why the memory-primary data
management architecture wins the disk-primary one in many performance-hungry
applications in telecom and Internet, often, by orders of magnitude.

About the speaker:
Cha received his BS in EE and MS in Control and Instrumentation Engineering
from Seoul National University in 1980 and 1982, respectively. He received
his Ph.D. from Stanford University in 1991. For his Ph.D. thesis, Prof.
Cha developed a knowledge-driven menu-guided pseudo-natural language query
interface to database and proposed a semantic data model for the acquisition
of knowledge for guiding the user's query composition. Since 1992, he has
been on the faculty of engineering at Seoul National University, where
he currently directs about fifteen Ph.D. and two-year master program students.
Prof. Cha has experience of working at the Data Communications Corp. of
Korea (DACOM), the Computer Science Center of Texas Instruments, Inc. in
Dallas, Texas, IBM Palo Alto Scientific Center, and HP Laboratories. His
current research focuses on the main memory DBMS architecture, implementation,
and application to telecom, Internet, and spatial database domains. Prof.
Cha, tired of chasing government funding, recently founded a company called
Transact In Memory, for the research, development, and commercialization
of a highly parallel transact in memory engine that he and his students
have developed.

Title:
Technologies for E-Business Solutions
-
Instructor: Ming-Chien
Shan, Hewlett Packard Laboratories
-
Abstract:
Electronic business will become the trademark of the 2000s. Today, enterprises
view the Web presence as a logical extension of their existing business
models in terms of business operations, distribution channels and marketing
media. To compete successfully, enterprises are demanding effective ways
to implement best-practices processes for electronic business on the Internet
and beyond. It requires a fundamental re-implementation of their
operational systems. Many new technologies are emerging to support this
need.
In this talk, I will review these technologies and their applications
in various E-business domains. I will introduce both front-end and back-end
systems and associated protocols. The main topics to be covered include:
- What are E-commerce, E-business, E-service and M-service?
- What operational system supports are required?
- XML and its e-business applications
- Workflow management and its e-business application.
- Emerging standards of B2B conversation protocols supporting marketplace operations.
- Data mining technology and its applications to e-business operations.

Title:
Content-based Retrieval from Multimedia Databases
-
Instructor: John R. Smith, IBM T.
J. Watson Research Center
-
Abstract:
With the tremendous growth in the amount of digital multimedia information,
it is becoming increasingly important to effectively store, search and
retrieve such information. Recent advances in multimedia databases
have resulted in technologies for managing a variety of multimedia formats
including images, video, audio, and text. In addition, advances in
content-based retrieval have resulted in new methods for querying multimedia
databases according to the audio-visual features of the multimedia content.
In order to enable interoperable searching, indexing, filtering, and retrieval
of multimedia, the Moving Picture Experts Group (MPEG) is developing a
new standard called the "Multimedia Content Description Interface," also
known as MPEG-7. The effort is being drivenby requirements taken
from a large number of applications related to multimedia databases, interactive
media services (music, TV programs), video libraries, and so forth.
MPEG-7 is achieving this goal by developing an XML-Schema based standard
for describing features of multimedia content. In particular, MPEG-7 provides
tools for describing multimedia content at the feature, syntactic, and
semantic levels, and for describing models that bridge the gap between
low-level features and high-level semantics.
MPEG-7 presents a number of significant technical challenges for
multimedia databases. Since MPEG-7 standardizes only the metadata
structures themselves (Descriptors and Description Schemes) and the Description
Definition Language (DDL), it is left open for industry competition and
future innovation to produce technologies for extracting, searching, and
filtering MPEG-7 descriptions. For one, new query methods are needed
for similarity matching with fuzzy constraints across the different levels
of multimedia content description, including features, structure, and semantics.
In addition, specialized database index structures are needed for MPEG-7
Descriptors because of their high-dimensionality and specialized metrics.
New methods are also needed for automatically classifying multimedia content
at the semantic level based on automatically extracted features.
In this tutorial, we study the problems of content-based retrieval from
multimedia databases, review the emerging MPEG-7 standard, and examine
the new challenges for supporting MPEG-7 in multimedia databases.
