    Frequently Asked Questions

    What is a data contracts tool?
    A data contracts tool formalizes expectations between data producers and consumers — covering schemas, validation rules, data ownership, SLAs, and data policies. Data contracts are a generalization of data tests: instead of only validating data at rest, they define the agreement around a data asset before data is produced or consumed. Most tools support YAML-based contract definitions and integrate with CI/CD pipelines to prevent invalid data from being materialized. Read more on my data quality tool market guide.
    Why create yet another tools list?
    I found no comprehensive, actionable, and up-to-date list of data quality tools. The MAD Landscape misclassifies 3 out of 19 data quality and observability tools. The Gartner Magic Quadrant for augmented data quality solutions lists 13 tools, half of which are enterprise data platforms, and I need to enter my professional email on a featured tool's website to get access to a reprint. Other lists by vendors contain a random sample of less than 10 tools, are written by AI, are highly biased, or are never updated.
    How can I edit this tools list?
