An organization usually operates its own mailing system to provide each person with an e-mail address under its domain name. There may exist a number of mailing lists in use, each of which refers to a group of its subscribers. The problem entailed in this ...
Efficient Retrieval of DNA Sequences Using Multi-way Clustering
Found in: Data Engineering Workshops, 22nd International Conference on
By Sungmin Joo, Motomichi Toyama
Issue Date:April 2005
pp. 1262
A retrieval on large DNA sequence data is very important in bioinformatics. However, it takes much time to search and comparison on large DNA sequence data. In this paper, we propose multi-way clustering for improving both the speed of retrieval and implem...
Providing Persistence or Sensor Streams with Light Neighbor WAL
Found in: Pacific Rim International Symposium on Dependable Computing, IEEE
By Hideyuki Kawashima, Motomichi Toyama, Yuichiro Anzai, Michita Imai
Issue Date:December 2002
pp. 257
Sensor database systems need to provide both freshness of data and persistence to the incoming sensor streams.To provide persistence,a disk based logging method has been widely used,however it is not applicable for sensor streams because of its tardiness.I...
Application of SuperSQL Query Language for the Migration from a Relational to an Object-Oriented Database
Found in: Database Engineering and Applications Symposium, International
By Shiro Udoguchi, Tadashi Iijima, Motomichi Toyama
Issue Date:September 2000
pp. 207
As the object-oriented programming proliferates and the new application areas like CAD emerge, shifting of the database technology to the object-orientation accelerates toward either object-oriented or object-relational databases. Consequently, the legacy ...
Hash-Based Symmetric Data Structure and Join Algorithm for OLAP Applications
Found in: Database Engineering and Applications Symposium, International
By Motomichi Toyama, Akira Ohara
Issue Date:August 1999
pp. 231
Star schema is often used in dimensional approaches applied to OLAP applications. The fact table in the star schema typically contains a huge amount of data. When some of the dimension tables are also very large, it may take too much time and storage to jo...

SuperSQL is an extension of SQL that allows query results presented in various media for publishing and presentations with simple but sophisticated formatting capabilities. SuperSQL query can generate various kinds of materials, for example, a LaTeX source...
Generating HTML sources with TFE enhanced SQL
Found in: Proceedings of the 1997 ACM symposium on Applied computing (SAC '97)
By Motomichi Toyama, Takuhiro Nagafuji, Toshiyuki Seto
Issue Date:April 1997
pp. 96-100
This paper describes the effects of program restructuring in a dataflow environment. Previous studies showed that dataflow programs can exhibit locality and that a memory hierarchy is feasible in a dataflow environment. This study shows that the order in w...
