How do analysts look at the data quality tool vendor market? As with everything data quality there are differences and apparently no single source of truth.
Gartner has its magic quadrant. They sell it for money, but usually you are able to get a free copy from the leading vendors.
The Information Difference has its DQ Landscape in the cloud for free.
It is interesting to compare which vendors are included in the latest main pictures, as I have tried below:
The number of x’s is a rough measure of the ability to execute / market strength.
Three smaller vendors are considered by Gartner, but not by The Information Difference and vice versa. Two midsize vendors are included by The Information Difference, but not by Gartner. Experian QAS are included as a big one by The Information Difference, but did not (yet) meet the inclusion criteria used by Gartner.
