This is the second issue of the ACM SIGMOD Digital Symposium Collection, DiSC. This year, we are especially
proud to feature the video of the exceptional SIGMOD/PODS plenary address by Dr. Jim Gray (Microsoft), the 1998
A.M. Turing Award Winner, entitled: ``What Next? A Few Remaining Problems in Information Technology.''
Last year, we mentioned that it was the aim of DiSC to become the ``most comprehensive and timely source of
information on database research.'' DiSC '00 has already obtained this objective, by including the full contents
of the proceedings of SIGMOD/PODS '99, VLDB '99, ICDE '99, KDD '99, CoopIS '99, DOA '99, DASFAA '99, SSDBM '99,
WebDB '99, and of the 1999 NSF Information and Data Management Workshop. The presentation slides and other material
for various invited talks, tutorials, demonstrations, and panels of SIGMOD/PODS, VLDB, CoopIS, and the EDBT Summer
School are also part of DiSC '00, as is the video of the SIGMOD/PODS keynote address by Dr. Theodore Berger (U.
of Southern California).
In this issue of DiSC, there are 3,792 HTML documents, 663 PDF files, 2,300 image files, and over 14,000 links.
To assemble this large, heterogeneous, and distributed multimedia data, we used a research prototype, called PANDA - A Publishing Assistant for Networked Document
Assembly - developed in the ADVIS Lab at WPI. All the information
presented in DiSC '00 was extracted, transformed, ``data cleaned," and finally integrated in a single XML
format using PANDA.
We hope you will enjoy the material herein and we welcome your comments and suggestions at our DiSC
feedback site. Copyright(C) 2000 ACM
