The traveling time to Kyoto JR station is approximately 75 minutes and fare is 3,490 yen (reserved seats), or 2,980 yen (non-reserved seats). Participants from foreign countries can purchase JAPAN RAIL PASS, which is a special discount pass for any trains of JR Group Railways (except the NOZOMI super express). JAPAN RAIL PASS is sold only outside of Japan: Must be purchased before arriving in Japan. For details, check website: http://www.japanrailpass.net/ ---- VISA ---- For entering Japan, you need a valid passport and in some cases a visa. To check whether you need a visa, and how to apply it, visit the homepage of the Ministry of Foreign Affairs (http://www.mofa.go.jp/j_info/visit/visa/index.html). Obtaining a visa may take a long period of time, a few months in some cases. So apply immediately if you need a visa. Ask Japanese Embassies/Consulates or local travel agencies for necessary documents. If you need a letter from the DASFAA2003 General Chair for visa application, please send mail to: dasfaa03@is.aist-nara.ac.jp ------------------ CONFERENCE PROGRAM ------------------ March 26 (Wed.) 9:30-10:30 Keynote: A Survey of New Directions in Database Systems Jeffrey D. Ullman (Stanford University) Abstract: As database system research evolves, there are several enduring themes. One, of course, is how we deal with the largest possible amounts of data. A less obvious theme is optimization --- it is an essential ingredient of all modern forms of database system. Because we deal with large volumes of data, we are often forced to process that data in regular ways. But when operations are uniform, there is an opportunity for the use of very-high-level languages, of which SQL is the primary example. However, to make a very-high-level language effective, we need to optimize it well, that is, produce effective query plans from all sorts of queries. In this talk, we shall review the principal directions in which modern database research is going, and in each case talk a bit about the optimization problems. Stream management systems are one very important new area. Another is peer-to-peer database systems. Integration of heterogeneous information, especially in virtual databases, is also a major challenge. XML, XQUERY, and semistructured data in general form yet another research opportunity. 10:50-12:20 Session 1: Spatial Query Processing Similarity Join for Low- and High- Dimensional Data Dmitri V.
