Analysts across departments cannot tell which curb-sensor feed is authoritative for downtown counts. Which architectural capability is missing?
Select an answer to reveal the explanation.
Short Explanation
If nobody can find the official sensor feed, the platform is a junk drawer. Catalogs and metadata turn piles of files into something people can trust and reuse.
Full Explanation
Usable Big Data platforms expose metadata and catalog services: dataset identity, ownership, freshness, lineage, and authority. Without them, analysts duplicate ingestions, pick stale feeds, and erode trust. Catalog capability is an architectural necessity alongside storage and compute, not an optional documentation afterthought.
