Which two statements describe the characteristics of an application module? (Choose two.)
A.
It provides the database transaction for the queries that it encapsulates.
B.
It defines view object instances to implement an application use case.
C.
It defines entity object instances to implement an application use case.
D.
There is a one-to-one mapping between view objects and application modules.
E.
Each ADF application has only one application module.
Explanation:
A: In general, one application module instance owns a single database transaction. All changes made through
that instance are made in a single transaction, which can be rolled back or committed at any time.
B: Oracle ADF application modules are business components that represent particular application tasks. The
application module provides a data model for the task by aggregating the view object and view link instances
required for the task. It also provides services that help the client accomplish the task. For example, an
application module can represent and assist with tasks such as:
Updating customer information
Creating a new order
Processing salary increases
Incorrect Aanswers:
D: An application module contains view object instances that retrieve the data needed by the client, as well as
view link instances that specify the relationships between the view object instances. The view object and view
link instances can be represented by a tree, called the application module’s data model.
