ConceptsOracle Application Express & Oracle SOA Suite

What is Oracle Application Express?
Rapid Application Development (RAD) Tool
Declaratively develop Web UI’s
Based on a Data source
BUT: Not necessarily database objects
12

What is the Oracle SOA Suite?
Fully Integrated Suite
Best-of-breeds SOA Tooling
Composite Editor
Service Bus
BPEL Process Manager
Business Rules
Web Service Manager
For UI’s basic choice: ADF
But not necessarily!
13

APEX vs. ‘SOA Suite’Pro
APEX:
Database Development
Declarative
Small. Effective.
Generated UI’s
Cheap
SOA Suite:
Processes
Application Integration
‘Non-Silo’
Services / XML / WSDL / (And other abbreviations)
Open Standards
14

APEX vs. ‘SOA Suite’Con
APEX:
Silo’s
Database Development
Propriety Standards (PL/SQL)
SOA Suite:
Big.
Large.
(ADF…..)
...
15

APEX vs. ‘SOA Suite’
“Both Oracle Application Express
and the Oracle SOA Suite are great,
but for their own target solutions”

SOAPEX: The Oracle SOA Suite and APEX

Three 'Streams'
APEX instead of ADF/JAVA/SOMETHINGELSE in a SOA Architecture
APEX is good for UI development
Used in ‘Silo’ Applications (Domain Specific)
Fast, reliable, easy to learn, …
Agile
The “Data-less” APEX application
All CRUD actions trough services
(Almost) no data within the APEX-app itself, just service calls.
APEX Custom Application Connecting to Other App’s trough SOA Suite
Combination of the above

APEX and SOA Suite Apps

Example: APEX and the Oracle E-Business Suite

APEX & Oracle EBSWhy?
Incorporating standard functionality Oracle E-Business Suite in Custom APEX application.
The less custom functionality in Oracle E-Business Suite, the better
Upgrading EBS
Maintenance
Overall ‘Simplicity’ of the EBS configuration
Custom development for ‘only’ one part of the Business
But without ‘redeveloping’ functionality already available
Reusing data and logic
Faster development & Easier deployment
No dependencies with other (EBS) projects
…
Oracle E-Business Suite offers an extensive library of interfaces.
Well documented
Proven
Tested
Supported
32

APEX & Oracle EBSIntegration Possibilities
Oracle E-Business Suite offers a lot of standard possibilities to integrate with external applications:
Interface tables
XML messages
EDI messages
PL/SQL API’s
Business Service Objects
Business Events
AND it’s all possible to enable these as Web Services using:
The Oracle E-Business Suite Integrated SOA Gateway
33

APEX & Oracle EBSThe Oracle E-Business Suite Integrated SOA Gateway
34

APEX & Oracle EBSHow?
How is this done?
E-Business Suite Integrated SOA Gateway
Deploy EBS’ (PL/SQL) API’s using the Integration Repository
Enclose services using the Oracle Service Bus
All WSDL / SOAP based, controlled and enabled
In APEX:
Call Services using the WSDL library as Web Service Reference
(CRUD actions on EBS done using these services)
APEX is just the Service Consumer
35

Example: APEX and Siebel CRM On Demand

APEX & CRM On DemandWhy?
SaaS (Software-as-a-Service) CRM solution from Oracle
Best-of-Breeds CRM
Online access
Small investment
Using APEX for Custom functionality
No changes in SaaS application (possible)
APEX has small ‘footprint’
Extensive Integration possibilities
Siebel CRM On Demand Web Services
Since 2006
Completely Standards-Based
Usable in SOA Suite & APEX
CRM information usable in Custom APEX Apps
Customer information
Deal & Opportunity information
Always ‘in sync’
Proven, tested, supported.
37

APEX & CRM On DemandHow?
Siebel CRM Web Services On Demand
All API’s available
CRUD actions on CRM entities
Incorporate services in Oracle Service Bus
External reference using the CRM On Demand Web Services Library
Ensuring a secure connection
Loosely-coupled
Access Services in APEX as Web Service Reference
Preferably using a UDDI / Service Registry
38

Consuming Services from APEXStandard

Consuming Services from APEXPreparation
Set up your environment
Oracle Database
Oracle WebLogic Server
Oracle SOA Suite
Oracle Application Express 4.1 (preferably in a separate database)
(APEX Listener)
All Web Service examples here are taken from the book “Getting Started with Oracle SOA Suite 11gR1, a Hands-On Tutorial” From Packt Publishing
Develop the Web Services, SOA Composites and BPEL processes as shown in the book.
And: Start your engines!
