Data Classification

urn:js:virtue:aspire:standard:13.1

TL;DR

All data columns in Snowflake will be tagged with their data classification. This classification will be recorded against the column.

Definition

You must determine the classification of the data that you are ingesting into the data warehouse. Once you have determined the classification, it must be recorded against that attribute (column).

In Snowflake, this must be done using Snowflake Object Tags, according to the data classification tag schema

Exception: Data in the experimental space is excluded from this requirement.
