View the Exhibit
A user interface requires a view of data for a customer order to include information about the order, items in the
order, and information about the customer who placed the order. The application entities and their relationships
are defined as shown in the Exhibit.
Which two steps would you perform to meet this requirement? (Choose two.)
A.
Create a default view object based on OrdEO, and add ItemEO and CustomerEO as reference entities to
the view object.
B.
Create default view objects based on OrdEO, ItemEO, and CustomerEO, and create view links based on
the defined associations.
C.
Create a view object based on SQL and define the SQL to select from the Ord, Item and Customer
database tables.
D.
Add attributes from the ItemEO and CustomerEO entities as needed.
E.
Create calculated attributes as needed from the Order, Item, and Customer database tables.
F.
Set the ItemEO and CustomerEO attributes to updatable=NEVER.
Explanation:
B: Oracle ADF view links are business components that define a relationship between two Oracle ADF view
object definitions (the “source” and “destination” view objects) based on sets of view attributes (the “source”
and “destination” attributes) from each. These can range from simple one-to-many relationships to complexmany-to-many relationships. This allows you to easily create master/detail relationships between data controls
in the client.
