Comparison of Supported Use Cases for Data Identifiers vs Classifications

This section quickly compares the supported use cases for different match conditions in both Data Identifiers and Classifications.

To understand the implementation of different use cases in both Data Identifiers and Classifications, see Use Cases Implementation.

Legends used in the table:   Supported     Not Supported

► Regular Expressions Match Use Cases
