Secondary review for the paper
"Data Conflict Resolution Using Trust Mappings”
by W. Gatterbauer and Dan Suciu

The paper proposes two algorithms for conflict resolution and their
modification for bulk execution through SQL queries.  The experimental
section covers the main resolution algorithm (RA) with two different data
sets, and its bulk execution using SQL Server.  Only the first experiment,
testing the java implementation of the RA algorithm over a synthetic data
set, was prepared for repeatability evaluation.

For the remaining experiments, the authors reported problems related to
outside access to their internal SQL Server installation.  One solution of
this problem could have been to detach the database and provide it to
reviewers who have an in-site SQLServer installation with pointers to the
modifications needed in the java code.

The primary review confirms the results of the experiment as well as the
worst case quadratic behaviour described in the text.  As part of the
workability evaluation additional experiments were performed with varying
graph configurations and the results obtained were as expected.
