This section describes the features introduced in Oracle Data Masking and Subsetting Release 13.1.
The following are the changes in Oracle Data Masking and Subsetting User's Guide Release 13.1.
Oracle Data Masking and Subsetting supports non-dictionary based referential relationships. The non-dictionary based referential relationships are application-specific referential relationships that are not defined in the Oracle data dictionary. For more information on using this feature, see the Application Data Modeling chapter.
Oracle Data Masking and Subsetting provides the ability to subset data based on partitioning. Subsetting based on partition and sub-partition enables you to include only those rows in the subset that belong to a particular partition or sub-partition of a table. For more information, see the Data Subsetting chapter.
Application Data Modeling and Data Masking components have been enhanced to support Edition Views. Support for Edition Views is essential to discover, mask, and subset applications such as Oracle E-Business Suite 12.2 or higher, which use edition-based redefinition for patching applications or upgrading databases, with minimal downtime. .
You can create an application data model with edition views, and mark the edition view columns as sensitive.
Data Masking will mask the base column that the edition view column is referring to.
For more information on Edition Views, see the Oracle Database Advanced Application Developer's Guide.
The following are changes in Oracle Data Masking and Subsetting User's Guide Release 12.1.0.8.
Oracle Data Masking and Subsetting supports Secure Shell (SSH) Key-based Host authentication to the target database host. For more information, see the Oracle Enterprise Manager Cloud Control Security Guide.
Oracle Data Masking and Subsetting provides the ability to model, mask, and subset the databases that are hosted in Oracle Cloud (DBaaS), in addition to the on-premise databases. In order to mask and subset data in Oracle Cloud (DBaaS), you must register the database in Oracle Cloud as a target for Oracle Enterprise Manager. For more information, see the Oracle Enterprise Manager Cloud Control Administrator's Guide.
