Data engineering·Governance, privacy and meaning
every column is tagged as public, internal or restricted, and the access rules are generated from the tags rather than written per table.
Data classification
Also calledsensitivity labelling, column tagging
Labelling data by sensitivity so that policies can be applied by label rather than table by table. It is what makes governance scale past a few dozen tables, because a rule expressed over a tag automatically covers next month's new table. Its weak point is coverage: an untagged column defaults to whatever the platform's default is, so the default has to be the restrictive one.
