Fintech teams in Hong Kong often invest in catalogues after a partner or regulator asks who owns customer transaction data. The tool arrives; the accountability question does not.
Before selecting software, list the five datasets that would stop a licence renewal or a bank partnership if mishandled. Put a named steward next to each one — a person who can answer purpose, retention, and access without forwarding the email three times.
Lineage diagrams then earn their keep: they show where those datasets travel, not where every log line goes. Audits move faster when the map is decision-sized.
