The Technology Evaluation Centers (TEC) have published an interesting, unbiased and independent analysis of the market for Open Source business intelligence products. We are delighted to see that the article features a section about data quality and that TEC points at DataCleaner as a competent choise within the open source products:

organizations can look to complementary open source solutions; the DataCleaner

data and monitor data quality. It also points to a significant advantage with
open source applications: the fact that software is developed by the community
and for the community makes it much simpler to share innovative solutions
quickly and seamlessly.
