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

Copyright © 2006 Oracle Corporation

Entity Objects – Persist Data

Copyright © 2006 Oracle Corporation

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

Copyright © 2006 Oracle Corporation

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

Copyright © 2006 Oracle Corporation

Using View Objects

Copyright © 2006 Oracle Corporation

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

Copyright © 2006 Oracle Corporation

Creating Entity Objects

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

Copyright © 2006 Oracle Corporation

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

Copyright © 2006 Oracle Corporation

Creating View Objects

1. Define type

2. Define data sources

Creating View Objects: Attributes And Settings

3. Choose attributes4. Set attribute’s properties

Copyright © 2006 Oracle Corporation

Creating View Objects: SQL Statement

Modify Query if needed

Copyright © 2006 Oracle Corporation

View Criteria – Dynamic Where Clause

• Define multiple query conditions

• Apply Selected condition at runtime

• Enables further view object reusability

Copyright © 2006 Oracle Corporation

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

Copyright © 2006 Oracle Corporation

List of Values

• Define at the attribute level

• Gets list from another view object

• Define type of list and list behavior

Copyright © 2006 Oracle Corporation

Defining Data Model for the Application Module

Copyright © 2006 Oracle Corporation

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

Copyright © 2006 Oracle Corporation

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

Copyright © 2006 Oracle Corporation

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

Copyright © 2006 Oracle Corporation

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

Copyright © 2006 Oracle Corporation

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
