Invited Speaker: Prof.Theo Härder
Title: Energy Efficiency is not Enough, Energy Proportionality is Needed!
Short Bio: Theo Härder obtained his Ph.D. degree in Computer Science from the TU Darmstadt, Germany in 1975. In 1976, he spent a post-doctoral year at the IBM Research Lab in San Jose and joined the project System R. In 1978, he was associate professor for Computer Science at the TU Darmstadt. As a full professor, he is leading the research group Databases and Information Systems (DBIS) at the TU Kaiserslautern since 1980. He is the recipient of the Konrad Zuse Medal (2001) and the Alwin Walther Medal (2004) and obtained the Honorary Doctoral Degree from the Computer Science Dept. of the University of Oldenburg in 2002. Hís research interests are in many DBIS areas, in particular, DBMS architecture, transaction systems, information integration, XML databases, and energy efficiency in database management. He is author/coauthor of 7 textbooks and about 300 scientific contributions with >160 peer-reviewed conference papers and >70 journal publications.
His professional services included numerous positions as chairman of DBIS in the German Computer Society, conference/program chairs and program committee member, editor-in-chief of Datenbank-Spektrum (Springer), associate editor of Information Systems (Elsevier), World Wide Web (Kluver), Computer Science – Research and Development (Springer), and Transactions on Database Systems (ACM).

Invited Speaker: Prof. Sang-Won Lee
Title: Some Research Directions in FlashDB
Short Bio: Sang-Won Lee is an Associate Professor in the School of Information and Communication Engineering at Sungkyunkwan University, Suwon, Republic of Korea. Before that, he was a research professor at Ewha Womans University and a technical staff at Oracle, Korea. He received a Ph.D degree, a M.S. degree, and a B.S. degree from the Computer Science Department of Seoul National University in 1999, 1994, and 1991, respectively.

Deadline for Submission of Paper EXTENDED!
   [December 15, 2010] Deadline of Paper submission extended to December 25, 2010

Recently, new storage media such as flash memory have been developed very quickly, which brings big challenges to the architecture of computer systems as well as the design of system software. In particular, NAND flash (either SLC- or MLC-based) in the form of solid state disks (SSDs) has been an alternative to traditional magnetic disks, both in the home-user environment and in the enterprise computing environment, due to its shock-resistance, low power consumption, non-volatile, and high I/O speed. The special features of flash memory and other new storage media impose new challenges to traditional data management technologies. As a result, traditional database architectures and algorithms designed for magnetic-disk-based storage fail to utilize new storage media efficiently. Meanwhile, the new characteristics of modern storage media, such as not-in-place update and asymmetric read/write/erase latencies of flash memory, also bring great challenges in optimizing database performance, by using new querying algorithms, indexes, buffer management schemes, and new transaction processing protocols. Consequently, exploiting the characteristics of flash memory and other new storage media has become an important topic of database systems research.

In order to make database systems adapt automatically to the characteristics of flash memory and other new storage media, the data management community needs to rethink traditional underlying storage architecture, query processing algorithms, indexing mechanism, buffer management schemes as well as many traditional issues in magnetic-disk-oriented database systems to adapt to the advances in the underlying storage infrastructure.

The aim of this one-day workshop is to bring together researchers who are interested in optimizing database performance on flash memory or other new storage media based storage infrastructure by designing new data management techniques and tools.
