The SIGMOD Awards Committee has selected for 2009:

Masaru Kitsuregawa is the recipient of the 2009 SIGMOD Edgar F. Codd Innovations Award for contributions to high-performance database technology. Kitsuregawa made major contributions to the development of hash-join algorithms, which significantly improved the performance of join operations in relational database systems. That work has influenced related research in areas such as query execution, plan optimization and dynamic query-workload balancing, as well as the development of commercial database products. He implemented the hash-based approach on a variety of platforms, including the Functional Disk System and multi-node PC clusters, demonstrating its substantial advantages through detailed evaluations. He has also applied hash-based strategies to parallel association mining and showed its effectiveness there. His contributions in the hardware area include a high-speed sorting system with a sophisticated memory management algorithm. That work was eventually commercialized in collaboration with colleagues, and won the Datamation sort benchmark in 2000. [citation]

Beng Chin Ooi is the recipient of the 2009 SIGMOD Contributions Award for his sustained and selfless contributions to the database community in promoting and pursuing high standards of database research at both the international and regional level. Beng Chin Ooi has been consistently involved in activities that push the frontier of database research. He has taken leadership roles on technical programs for ICDE, SSD, SIGMOD and VLDB. He has helped ensure a high standard for database journal publications as an editor for The VLDB Journal, IEEE Transactions on Knowledge and Data Engineering, International Journal of Geographical Information Science, and Geoinformatca. Currently, he is the editor-in-chief of IEEE Transactions on Knowledge and Data Engineering, and an editor for the Distributed and Parallel Databases journal. He also serves on the SIGMOD Doctoral Dissertation Award committee and on the board of the VLDB Endowment. Ooi has contributed greatly to promoting database research, especially in the Asia-Pacific region, by building a eminent database group at the National University of Singapore that supports high quality research throughout the region through direct collaborations and participation in regional conferences.

The recipient of the 2009 SIGMOD Test of Time Award is:

This influential paper showed that aggregates over sparse, high-dimensional arrays can be approximated with wavelets to give a compact data-cube representation that supports queries at interactive speeds. Prior histogram- based methods had prohibitive I/O costs for massive data sets of high dimensionality. The method is more accurate than random sampling and supports progressive refinement of answers when additional accuracy is desired. The paper inspired significant follow-on work by others, in the OLAP domain and also more broadly in approximate query processing, selectivity estimation, indexing of images and time series, and data-stream processing.
