Data catalog
Data catalog is an organized inventory of an organization's data assets, with metadata, definitions, ownership, and lineage to help people find and trust data. For data catalog, a useful definition states an organized inventory of an organization's data assets, with metadata, definitions, ownership, and lineage to help people find, who owns it, and which decision it supports.
Also known as metadata catalog, data discovery catalog
Why it matters
Understanding data catalog matters because leaders need a shared, source-backed meaning before they can compare results, explain performance, or decide what to do next. When the term is tied to a source system, owner, and review cadence, it becomes easier to audit assumptions, catch changes early, and keep operators aligned.
In practice
Operating example
Data catalog is useful when teams need a shared interpretation of an organized inventory of an organization's data assets, with metadata, definitions, ownership, and lineage to help people find and trust data. The definition should make source data, timing, ownership, and the decision it supports explicit.
Review example
Data catalog should be reviewed whenever the source system, calculation logic, time period, or decision owner changes. That keeps the definition useful instead of letting it drift into a label.
In practice, teams should define data catalog with a clear source, owner, time period, and decision before they use it in reporting, planning, or operating reviews.

When the term is tied to a source system, owner, and review cadence, it becomes easier to audit assumptions, catch changes early, and keep operators aligned.
A strong workflow for data catalog separates the definition from the action: first agree what the term means, then decide how it is measured, when it changes, and who is accountable for the next step.
