Stanford Trio System available for public use

The Trio system, under development in the Stanford InfoLab, is now
available for use over the web. You can create your own databases or
use our samples, and you can run ad-hoc queries and browse the results.
(Currently, we are not distributing Trio source code, but we plan to
do so in the near future.)

Trio is a new kind of DBMS in which data, uncertainty of the data, and
data lineage are all first-class citizens. Trio is based on an
extended relational model called ULDBs, and it supports a SQL-based
query language called TriQL.
