What does the Application Data Modeling module of the Oracle Data Masking and Subsetting Pack search for?

The Application Data Modeling (ADM) feature is a discovery module within the Oracle Data Masking and Subsetting Pack. Its primary purpose is to scan the application's data dictionary to discover sensitive data and, crucially, the relationships between tables. It identifies primary key and foreign key (parent/child) relationships to build a data model. This model is essential for creating valid, referentially intact subsets of production data for non-production environments and for applying masking consistently across related columns.

A. Data redaction is a separate security feature for redacting data in real-time queries; it is not the function of the ADM module.
B. Data masking transformations are the specific masking routines applied to data, which occurs after the ADM has discovered the data and its relationships.
D. Encrypted columns are handled by Transparent Data Encryption (TDE). While ADM might identify these columns, its core function is modeling relationships, not searching for encryption.
