This is the distribution of a modified version of the TPC-H data generator
|
|
developed by the MayBMS team (http://maybms.sourceforge.net) which was used
|
|
in the experiments of the paper
|
|
|
|
Fast and Simple Relational Processing of Uncertain Data.

L. Antova, T. Jansen, C. Koch, D. Olteanu. Proc. ICDE 2008.

This directory contains the following files:
|
|
|
|
* uncertain-tpch/ -- the source code of the data generator.
|
|
|
|
* query1.sql, query2.sql, query3.sql -- example queries used in our
|
|
experiments.
|
|
|
|
* urel-attr-tuple.sql -- this SQL script joins the U-relations generated
|
|
by the data generator together, i.e., it maps an attribute-level
|
|
representation achieved by vertical decompositioning to a tuple-level
|
|
representation.
|
|
|
|
* urel-ULDB.sql -- this SQL script maps tuple-level U-relations to Trio
|
|
ULDBs.
