Oracle ADF Architecture

The Business Service Layer
 Manages Persistence
- O/R mapping
- Queries/DML
 Performs Validation
- Data validation
- Business logic
 Choices of implementation
- ADF Business Components, JPA Entities, Web
Services, Java classes

ADF Business Components Characteristics
 Provides data interaction & business logic execution
 Maps to a data source
 Enable 4GL development
- Declarative and visual development
- Implemented in metadata
 Enables business logic development
- Declarative business rules
- Pre-defined Java methods for events
 Can expose application modules as services
 Based on Java and XML

Artifacts of ADF Business Components

Entity Objects
• Maps to a row in a database table
• Handles insert, update, delete operation
• Define behaviors for attributes
• Can continue validation and business logic

Entity Objects – Persist Data

Associations
 Define a relationship between Eos
 Facilitate access to data in related entity
objects
 May be based on database constrains
 May be independent of database
constraints
 Are used in defining validation and LOV
 Consist of a source (master) and a
destination (detail) entity

View Objects
 Represent a query
 Are used for joining, filtering, projecting, and
sorting business data
 Enable you to have a view of data that is specific to
one part of your application
 Can be constructed from a SQL statement, static
values, or populated programmatically
 Can also be based on any number of entity objects

Using View Objects

Using View Objects
Application Modules:
• Contain an active data model that the client uses to interact
with view object instances
• Control the connection to the database and keep track of all
changes that affect data in the database
• Provide remotely accessible methods to implement
application module behavior
• Are easily reused

Creating Entity Objects
1. Map to Table 2. Choose/add attributes 3. Set attribute properties

Defining Attribute’s Properties
 Control functionality and
behavior
- Mandatory
- Default value
- Refresh on update
- More
 UI Hints – default UI
representation
- Label
- Tooltip
- Format mask
- Control type

Creating View Objects
1. Define type
2. Define data sources

Creating View Objects: Attributes And Settings
3. Choose attributes
4. Set attribute’s properties

Creating View Objects: SQL Statement
Modify Query if needed

View Criteria – Dynamic Where Clause
• Define multiple query
conditions
• Apply Selected condition at
runtime
• Enables further view object
reusability

Linking View Objects
 Join query
- Define at view object query
- Can be updatable
 Master/Detail
- Define with view links
- The detail item belongs to the
master

List of Values
• Define at the attribute level
• Gets list from another view
object
• Define type of list and list
behavior

Defining Data Model for the Application Module

ADF Business Components – XML and Java
• ADF BC uses XML metadata to describe the objects
• By default there are no Java files created
• In many cases you don’t need java files
• However if you want more complex logic you’ll put that in a Java
file overriding default behavior
• You can create Java files for EO, VO and AM

Adding Logic to your Entity Object
• The *Impl file is the
one you’ll mostly
use
• Then choose which
default method to
create
• You only need to
create the one you
want to override

Finding Hook-Points
 Use Source -> Override
Methods to locate an
event you want to inject
code into
 You have access to:
- Set/get for attributes
- Transaction events
- Creation/remove events
- DML events
 Similar to Oracle Forms
Triggers

Access Your Application Module
• AM exposes view Objects, links and
default operations on the views
• You can add methods to the AM
• AM is exposed to UI developers in the
Data Control Palette
• Drag and drop AM content into your
page to build the UI

Exposing Your Business Service to Other System
 Create SCA/SDO interface to
business services declaratively
 Automates creation of:
- Java interface – defines the service
- EJB 3.0 session bean – implements
the Java interface
- WSDL file – describes the service’s
operations
- XML Schema Document (XSD) –
defines the service’s data
structures
 Integration with Oracle’s SOA
Suite

FUSION MIDDLEWARE
FRAMEWORK ADF Faces

Web User Interface in Oracle ADF
 MVC approach to web UI development
 Based on JSF – the Java EE Standard MVC framework
 Extended capabilities provided by Oracle ADF
- ADF Faces – richer set of JSF components
- ADF Controller – extended controller with reusable task flows
- ADF Binding – simpler binding of view and controller to business
services

Oracle ADF – High Level Architect

Declarative Partial Page Rendering (PPR)
Partial Page Rendering:
• Enables redrawing only a portion of a page
• Can be enabled declaratively or programmatically

JavaScript API
• Interact with ADF Faces components from client side
JavaScript
• Allows you to have a client representation of the component
• Catch events and react on the client side
• Invoke server side events from client side JavaScript code
• As a rule – try to minimize the usage of this feature

Templates
• Reusable ADF Faces page that contains place holder for custom
page content
• Templates are interpreted at runtime
• Authors can change the template for an existing application
without opening the application itself
• Templates can have their own ADF binding file
• Templates may accept parameters for passing information from
the inheriting page to the template

Declarative Components
• Construct composite components from other components
• Can customize behavior using attributes, methods, and facets
• Package components for reuse in other applications
