Terminology

991 terms, tools, patterns and metrics an architect is expected to use precisely. Each one gets a short explanation of what it is, and — where it matters — what it is commonly confused with. Search filters as you type; the column headers sort.

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.
Computation-Only Collaboration	pattern	Data Sharing & Clean Rooms	Two parties analysing their combined data without either receiving the other's records, by permitting only queries whose outputs are aggregate.
Data Product Interface	concept	Data Products	The stable surface a data product exposes — its schema, its access path, its documentation and its guarantees — as distinct from the pipeline behind it.
Decision Rights Over Data	concept	Data Governance & Semantics	Who is entitled to decide what a data element means, who may see it and how long it is kept — the substance of governance once the policy documents are set aside.
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.
Domain Data Ownership	concept	Data Mesh	Making the team that generates data accountable for publishing it fit for others to use, rather than handing raw extracts to a central team.
Golden Record	concept	Master Data Management	The single authoritative version of an entity assembled from conflicting sources, and the survivorship rules that decide which value wins.
Governed Self-Service	concept	Self-Service vs Governed	Letting anyone analyse anything while constraining what may be treated as authoritative, which resolves the apparent conflict between speed and consistency.
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.
Metric Definition Layer	pattern	Semantic Layer	Business metrics defined once in a versioned, tested place and served to every consuming tool, so the number cannot differ by which tool asked.
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.
Predicate-Based Filtering	pattern	Row & Column-Level Security	A policy that appends a filter to every query on a table based on who is asking, so one physical table serves many audiences safely.
Producer Obligation	concept	Data Contracts	What a data contract binds the producing team to do, and — crucially — what happens in their pipeline when they are about to break it.
Purpose-Based Access	pattern	Data Access Models	Granting access for a stated and recorded purpose rather than by role alone, which is what several data protection regimes actually require.
Quality Dimension Threshold	metric	Data Quality Dimensions	The stated numeric level at which a dataset is fit for its purpose on a given quality dimension, plus what happens when it is not met.
Sensitivity Propagation	concept	Sensitivity Labelling	The rule that a derived dataset inherits the highest sensitivity of its inputs unless a named transformation demonstrably lowers it.
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.
