ADF Exams questions and so possible interview questions

These are ADF Exams questions and so possible interview questions
In blue I ll try to give some possible answers or "sources for answers".

Introduction to Fusion and ADF
[  ]Describe Fusion Architecture
Check: Check Part I Chapter 1 : What Is Fusion? in  Oracle JDeveloper 11g Handbook (reference:

[  ]
Explain how ADF fits into the Fusion architecture
The ADF is the framework used to build Fusion Web Apps.
The Oracle Application Development Framework (Oracle ADF or just ADF) is a meta-framework
that fulfills the core requirements for a framework as outlined in the preceding section. ADF
integrates a mix of subframeworks to provide the key functions for object-relational mapping and
other forms of service access, data bindings, and user interface, along with the functional glue to
hold it all together (reference:

This chapter describes the architecture and key functionality of the Oracle Application Development Framework (Oracle ADF) when used to build a Fusion web application that uses Oracle ADF Business Components, Oracle ADF Model, Oracle ADF Controller, and Oracle ADF Faces rich client, along with high-level development practices. Check:
[  ]
Describe the ADF technology stack (MVC)
[  ]
Identify sources of additional information about ADF and ADF Business Components

  • Check "Resourses" in the bottom of the blog and also posts with Resource label 

Getting Started with JDeveloper
[  ]
Describe benefits that JDeveloper provides for application development
[  ]Utilize common IDE mechanisms when developing and testing components
[  ]Set IDE preferences based on user requirements
[  ]Initiate the creation of empty applications, projects, and connections in JDeveloper

Building a Data Model with ADF Business Components
[  ]Describe the role of ADF Business Components in building a business service

[  ]Explain the architecture of ADF BC

Oracle ADF Business Components is a framework implements the Business Services layer on top of a data source in a declarative way. It provides out-of-the-box services such as transaction management, resource pooling, locking, declarative validation rules, translation, and object-relational mapping. 
To use Oracle ADF BC, you use wizards in JDeveloper to create:
  • Application Module
    • An application module is a service component that UI or Web Service clients use to work with application data. It defines an updatable data model and top-level procedures and functions (called service methods) for a logical unit of work related to an end-user task. To simplify the task of implementing your services, you leverage a set of business components like entity objects and view objects.
    • You can enable a service interface on any Application Module. The service interfaceexpose Application Modules as remotable services allowing third-party applications to find, create, update and delete business information using standard web services protocols. All of the business validation rules encapsulated in your Entity Objects are automatically enforced through this service interface as well.
    • You can use any application module both as a local component and as remotely-accessible service. This allows you to support both interactive Web user interfaces as well as programmatic Web-service clients with the same component.
  • Entity object
    • An entity object represents a row in a database table and simplifies modifying its data by handling all DML operations for you. It can encapsulate business logic for the row to ensure your business rules are consistently enforced. You associate an entity object with others to reflect relationships in the underlying tables to create a layer of business domain objects to reuse in multiple applications.
  • View object
    • view object represents a SQL query and simplifies working with its results. You declaratively join, project, filter, sort, and aggregate entity object data into exactly the "shape" required by the end-user task at hand, including the ability to link a view object with others to create master/detail hierarchies of any complexity. When users modify business data using a view object, that component automatically collaborates with entity objects to consistently validate and save the changes.
The following diagram illustrates the relationship among application module, entity object, and view object. A view object defines a query and produces a row set of rows. View objects and entity objects collaborate to enable an updatable data model. Application module contains view objects and it provides transaction.
