Great advances have been made in the database field. Relational and
object- oriented databases, distributed and client/server
databases, and large-scale data warehousing are among the more
notable. However, none of these advances promises to have as great
and direct an effect on the daily lives of ordinary citizens as
video databases. Video databases will provide a quantum jump in our
ability to deal with visual data, and in allowing people to access
and manipulate visual information in ways hitherto thought
impossible. Video Database Systems: Issues, Products and
Applications gives practical information on academic research
issues, commercial products that have already been developed, and
the applications of the future driving this research and
development. This book can also be considered a reference text for
those entering the field of video or multimedia databases, as well
as a reference for practitioners who want to identify the kinds of
products needed in order to utilize video databases. Video Database
Systems: Issues, Products and Applications covers concepts,
products and applications. It is written at a level which is less
detailed than that normally found in textbooks but more in-depth
than that normally written in trade press or professional reference
books. Thus, it seeks to serve both an academic and industrial
audience by providing a single source of information about the
research issues in the field, and the state-of-the-art of practice.
Replication Techniques in Distributed Systems organizes and surveys
the spectrum of replication protocols and systems that achieve high
availability by replicating entities in failure-prone distributed
computing environments. The entities discussed in this book vary
from passive untyped data objects, to typed and complex objects, to
processes and messages. Replication Techniques in Distributed
Systems contains definitions and introductory material suitable for
a beginner, theoretical foundations and algorithms, an annotated
bibliography of commercial and experimental prototype systems, as
well as short guides to recommended further readings in specialized
subtopics. This book can be used as recommended or required reading
in graduate courses in academia, as well as a handbook for
designers and implementors of systems that must deal with
replication issues in distributed systems.
Mobile communications havepermeated the globe in both business and
social cultures. In only af ew short years, Japan aloneh ash ad
more than ten million subscribers enter the mobilem arket. Such
explosive popularity is an indication ofa strong commercial demand
for communications in both the tethered and tetherless
environments. Accompanying the vibrant growth in mobile
communications is the growth in multimedia communications,
includingthe Internet. Mobile and multime dia communications
technologies are merging, making mobile computing ak ey phrasei n
the coming advanced information communication era. Thegrowth i n
these dynamic industries shows that achange in our chosen method of
commu nications is already well advanced. Reading e mail and
connecting to various information feeds have already become a part
ofdaily business activities. We are trying to grasp theo verall
picture of mobile computing. Its shape and form are just starting
to appear as personal digital assistants (PDA), handheld personal
computers (HPC), wireless data communication services, and com
mercial software designed for mobile environments. We are at the
cusp of vast popularization of "computers on the go. " "Any time
Anywhere Computing" provides the reader with an understand able
explanationo ft he current developments and commercialization of
mobile computing. Thec oret ec hnologies and applications needed to
un derstand the industry are comprehensively addressed. Thebook
emphasizes three infrastruc tures: (1) wireless communication
network infrastructure, (2) terminal devices (or "computers on the
go"), and (3) software middleware and architectures that support
wireless and mobile computing.
