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 attributes4. 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

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 ArchitectMVC – Model View controller

Pie

Bar

Point


Pivot Table

• Automatic calculation of subtotals and totals

• Drag and drop pivoting


Gantt Chart

Track tasks and resources on a Time

Gantt Chart types Project Gantt

Scheduling Gantt

Resources Gantt


Hierarchy Viewer

Hierarchical data representation

Expand/collapse/isolate nodes

Zoom in/out

Change layout

Include ADF Faces components in nodes


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
