Which option represents the steps to add a relationship between OrdVO and ItemVO and create a masterdetail 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.
Right-click the association on the diagram and select Generate View Link.
Explanation:
When you want to show the user a set of master rows, and for each master row a set of coordinated detail
rows, then you can create view links to define how you want the master and detail view objects to relate.To create an association-based view link, you use the Create View Link wizard.
Note: A master-detail relationship is established when a view link is created to associate two view object
instances. A view link represents the relationship between two view objects, which is usually, but not
necessarily, based on a foreign-key relationship between the underlying data tables. The view link associates a
row of one view object instance (the master object) with one or more rows of another view object instance (the
detail object).
