A minor update has been added to the Technical Best Practices in response to some customer feedback. There are some instructions on how to build a data model for data modelling tools such as SQL Developer Data Modeler and Enterprise Manager's Data Masking and Subsetting Pack (formerly known as Test Data Management Pack).
The SQL to build the model has been updated to include some additional constraints available in OUAF 4.2 and above.
Customers intending to build the data model using this technique should refer to the updated instructions in Technical Best Practices for Oracle Utilities Application Framework Based Products (Doc Id: 560367.1) available from My Oracle Support.
