Stanford Trio System Open-Source Code Now Available

The Trio system, under development in the Stanford InfoLab, is now
available in open-source under the BSD license.

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.

The Trio prototype runs under Linux, Mac OS X, and Win-32. It includes
a Python API, a command-line interface, and a browser-based graphical
user interface that runs in Firefox, Safari, and Internet
Explorer. The download comes with few sample databases and queries.

Trio is also available for use over the web without downloading and
installing the system. You can create your own databases or use our
samples, and you can run ad-hoc queries and browse the results.

binaries, or web-accessible system, please visit:
