An example of a data table column with high-cardinality would be a USERS table with a column named USER_ID. This column would contain unique values of 1- n . Each time a new user is created in the USERS table, a new number would be created in the USER_ID column to identify them uniquely.

An increasing purpose of the medical record is to ensure documentation of compliance with institutional, professional or governmental regulation.
Cardinal functions are widely used in topology as a tool for describing various topological properties.
