Term	Kind	Topic	What it is
Certified Report	practice	BI Governance	A small set of reports explicitly endorsed as authoritative, with an owner and a review cadence, distinguished from everything else people have built.
Code List Governance	practice	Reference Data	Managing the small shared enumerations — currencies, country codes, statuses, product categories — whose uncontrolled change breaks systems quietly.
Deletion Verification	practice	Retention & Purge	Proving that a deletion actually removed the data everywhere it existed, which is a harder problem than issuing the delete.
Deterministic Tokenisation	practice	Tokenisation & Masking	Replacing a sensitive value with a stable surrogate so the same input always yields the same token, preserving joins while removing the value.
Metadata Harvesting	practice	Data Catalog	Populating a catalogue automatically from the systems that hold the data, because anything requiring manual entry will be incomplete within a quarter.
Pipeline Anomaly Detection	practice	Data Observability	Monitoring row counts, distributions, freshness and schema for unexplained change, because data pipelines fail silently far more often than they error.
Steward Accountability	practice	Data Stewardship	Making stewardship a defined role with time, authority and consequences, rather than a title added to somebody's existing job.
Term Definition Ownership	practice	Business Glossary	Assigning one accountable owner per business term, so that a disagreement about meaning has a route to resolution rather than a standing argument.
