Oracle 1Z0-419 Exam Questions & Answers

The EmployeesVO view object is based on the Employees table and includes a Deptld attribute.

However, Deptld is not really meaningful to the end user and so, for each employee returned by EmployeesVO. you need to show the correct DepartmentName, which comes from the Departments table and is referenced by the EmployeesVO Deptld attribute.

How can you achieve this behavior by using the declarative features of ADF Business Components? (Choose the best answer.)

A. Add a transient attribute to EmployeesVO and set its value to select DepartmentName from Departments where Deptld = EmployeesView.Deptld

B. Create a database view to join the Departments and Employees tables and base the view object on that view.

C. Define that EmployeesVO is also based on the Departments entity object. Then select "Add attribute from entity" in the EmployeesVO view object and select DepartmentName from the Departments entity object.

D. For the EmployeesVO view object, select the query and add WHERE Employees DEPARTMENTJD = Departments.DEPARTMENTJD

E. Add a transient attribute called DepartmentName in the view object and, in the ViewRowlmpI class, override the getDepartmentName() accessor to: return (String) getAttributelnternal (DEPARTMENTNAME);

Which two are reasons why you might set the bind variables of a view object at run time programmatically rather than using the declarative features of the framework? (Choose two.)

A. The framework can set only one bind variable declaratively on each view object query. Attempting to set more bind variables requires a programmatic solution.

B. After a bind variable is set using the declarative method, its value is immutable unless updated programmatically.

C. In all cases, ADF developers should code solutions rather than using declarative solutions

D. The bind variable is derived by calling a Java method rather than receiving the value from a user.

E. The bind variable value entered by and understandable by a user must be modified using Java code to a value that can actually be used in a query.

View the Exhibit Which option represents the steps to add a relationship between OrdVO and ItemVO and create a master-detail hierarchy for the same in the data model? (Choose the best answer.)

A. Select View Link from the Components window and draw a line on the diagram from ItemVO to OrdVO. Use the Application Module Editor to define the data model for the hierarchy.

B. Create a view link with OrdVO as the source and ItemVO as the destination and define the linked attributes Use the Application Module Editor to define the data model for the hierarchy.

C. Create a view link with ItemVO as the source and OrdVO as the destination and define the linked attributes. Use the Application Module Editor to nest the OrdVO instance beneath the ItemVO instance.

D. Select Association from the Components window and draw a line on the diagram from OrdEO to ItemEO diagram and select Generate View Link
