Modifying the Default Behavior of Entity Objects

• With declarative settings, you can:

• Define attribute control hints
• Synchronize columns with trigger-assigned values
• Use alternate key entity constraints
• Validate user input (presented in the lesson titled “Validating User Input”)

Notes:

Modifying the Default Behavior of Entity Objects

Next you learn to synchronize entity object attribute values with database columns whose values are assigned by database triggers. The most common example of this is when a database trigger assigns a primary key value from a database sequence.
