Which statement is NOT true regarding the Data Masking transformation?

The Data Masking transformation is categorized as an active transformation because it modifies the data that passes through it, which means that the structure or content of the data can change in the output based on defined rules. The transformation applies specific masking techniques to protect sensitive information, making it less recognizable or incomprehensible to unauthorized users while still retaining a level of usability for authorized purposes.

The assertion regarding it being primarily used for sensitive data handling is also true, as the main purpose of data masking is to protect privacy and comply with regulations when dealing with sensitive personal data. The statement about modifying data according to configured rules is also factual, emphasizing how it enforces specific masking transformations based on pre-established criteria.

The claim about not being able to maintain referential integrity is correct in context, as applying data masking could potentially alter the relationships between data elements if not managed carefully, especially when dealing with dependent fields. This reinforces that data masking should be executed with awareness of its potential impacts on referential integrity in the overall data architecture.

In summary, the transformation is indeed an active one, directly resulting in changes to the data as it processes, which is critical to understand for effective data management and compliance.
