FUSION APPS ARCHITECTURE OVERVIEW


Fusion Application Definition• Fusion Applications are Service-Oriented composite

enterprise applications developed and deployed based on the Oracle Fusion Architecture, using Fusion Middleware. – ADF Fusion Applications are applications developed using

Oracle Application Development Framework (ADF). ADF ensures adherence to Fusion Architecture.

– Oracle Fusion Applications are being designed by Oracle to unify best-of-business capabilities from all Oracle Applications in a complete suite delivered on Oracle’s open technology. These are packaged enterprise applications built using ADF and SOA

– Custom Fusion Applications are applications realized using Oracle Fusion Architecture

FUSION APPS USER EXPERIENCE - ADF


Service Layers and ADF

• Presentation Services– ADF task flows and JSF page flows– ADF Faces

• ADF data visualization rich client components (charts, graphs, gauge etc…)– Meta Data Services (MDS) – customization– ADF Mobile and ADF Swing Services– ADF Active Data Services

• Business Process Services– Supports two-way interaction with BPEL processes

• ADF bounded task flow can be invoked by BPEL business processes.• BPEL can invoke bounded or unbounded task flow and application modules (through web service

controls)– ADF Task Flows implement simple intra-application sub processes

• Business Activity Services– Application Modules implement business logic and expose as Services

• Application modules wrap Entity Objects and View Objects• Entity Objects may have custom Java logic embedded• Stored procedures and DB functions can be invoked using custom Java classes.• Declarative or programmatic validation and business rules logic (Decision Services)• SCA composite access support – Service enabled application modules

– Web Service data control to expose external business logic to the UI layer; inrtra-application scope• Data Services

– ADF Application Modules expose data access Services that use EO and VO• ADF Entity Objects represent business entities in the database• ADF View Objects represent queries that return business entities

• Connectivity Services– ADF application modules with backend integration using a variety of methods that include JCA, file based

integration, Oracle adapters and other Java based integration• Utility Services

– ADF application modules to implement Services that may or may not access database (e.g. Alert, logging, or email)

Loose coupling and abstraction

• Model View Controller (MVC) architecture• Layered Architecture• Standards based interfaces• JSR 227 – Data binding allows decoupling

of UI from the business service implementation using declarative binding.

• Data controls encapsulate access to the business components and decouple UI


Layered Architecture• Well defined Layering scheme with MVC

architecture– Model Layer– View Layer– Controller Layer– Business Services Layer– Data Layer

• Clearly defined separation of concerns


Reusability

• ADF promotes both design-time (code/component) and runtime (Services) reuse – Design-time: Services can be rolled up into an ADF

library or a Resource Catalog that includes ADF library and infrastructure connectivity components, and shared with application or Service development teams for consumption.

– Runtime: Business services can be built and deployed centrally for consumption through supported interfaces that include Web Services/WSDL, EJB 3.0 and message-based.


Agility

• Model driven development – Allows changes to be made quickly to respond to changes in business

• Component based development – makes it easy to reconfigure and update business logic flow

• Modular , loosely coupled design allows components to be updated independently without affecting other parts of the application (e.g. UI can be updated independent of the business components)

• Built-in patterns standardize application/Service development and enable faster delivery.


Separation of concerns

• Layering – Model-View-Controller (MVC) pattern– Business Services Layer

• Data binding (JSR 227)– Allows UI to be separated from the business components

• ADF business components (Entity Objects Vs View Objects Vs Application modules) define the scope of the components clearly

• Data controls allow abstract invocation of business logic from the UI.


Composability

• Supports composability at multiple levels

• Application modules are composed of Entity Objects and View Objects

• Supports Service Component Architecture – programming model for building Services that can be consumed by SCA composites.

• Task flows can include other task flows


Discoverability

• UDDI support to publish and discover Services

• Components, application libraries and projects that can be packaged and reused. They can be linked and discovered through an Enterprise Metadata Repository like Oracle Enterprise Repository.

• Resource catalogs enable localized discovery of application components.


Standards Compliance

• Open standards based framework• Supports the following standards

– J2EE– JSR 227– Web Services (SOAP, UDDI, WSDL)– WSRP, JSR 168, JSR 268– Service Component Architecture (SCA)– SDO (Service Data Objects)– Security (JAAS, X509, SAML)– JCA, JPA, JMS, JDBC


Security

• ADF supports Authorization and Authentication• Access policies can be defined and executed• WS-Security is supported• Web Service data control security includes

– X509 token authentication– SAML authentication– SAML assertion– Digital signatures– SOAP encryption and decryption


Principles and best practices

• Define “Service” before developing Services using ADF.• Validate the database models against business requirements and

functional models before generating entity and view objects.• When creating an application module that deals with multiple business

entities, each business entity must be abstracted with a respective Entity object.

• Service Contract and interfaces should drive the design and development of ADF business components.

• Web Services interface must not be used for intra application module communication.

• ADF Fusion applications must be designed with future customization support. (e.g. prefer jspx over jsp)

• View objects should be driven by business requirements. View objects should not be used for simply representing a row of the physical data model.

• Data controls should be used to abstract the business services implementation from the UI components.

• Applications developed using ADF must be deployable on any Java-capable application server.

• Visual and declarative validation should be used when applicable.

• DISCUSSION: Any additional principles and best practices???


ADF Fusion Application development best practices

• ADF is used to develop Service-Oriented Applications. That means that you can develop both Services and Composite applications with ADF.

• Services: ADF can be used to build SOA Services that can be exposed using a choice of interfaces

• Composite applications: Composite applications that consume Services and other business components can be built using ADF. ADF also helps rapid development of UI components.

• Enterprise Services should be identified during the analysis phase and should be designed, developed and deployed in a shared environment for the consumption of the ADF composite application.

• Disaster Recovery configuration• Distributed deployments?• Deployment best practices

SOA Solves Legacy Pains

Pain Points Fusion Apps ProcessesBlack box processes Integration friendly, visible and documented

Difficult to configure Centrally configured using BPEL

Difficult to monitor Centrally monitored using Enterprise Manager

Difficult to change at runtime Rules and approvals can be ‘Design Time at Runtime’

Difficult to customize Customized using the BPEL editor

Difficult to retain extensions Layered customizations

Proprietary implementation BPEL and BPMN provide standards based platform

Compliance Easier for auditing and compliance

Difficult to govern Seamless integration with OWSM and EM

Usage Category Description UsageProcess Customization (for Developers)

Developers customize processes to suit business needs.

• Simple sequential BPEL process steps• Customer can modify steps

Human Workflow Support human workflow with complex approvals including approval hierarchies

• Most important usage by many fusion apps• Manual task or approval tasks

Integration Decouple external systems. Allows bringing new systems online without changing core Processes

• Mediator is an example• End to End Integration • Flexibility with Rules based routing

Process Composition (for Business Analysts)

Make it easier for business analyst to modify process at runtime.

• Business Analysts arrange orchestration flow of delivered processes

• Process Composer use case

Long Running or Batch Processing

Support Batch processing and other long running jobs as scheduled /async processes

• Executed as a batch or is a long running process

• Processing itself happens outside• Orchestration, fault handling and

compensations are key

Event Processing Support event processing using SOA model.

• Event driven integration• Events to add flexibility and loose coupling

Key Usages Of SOA in Fusion Applications

Customization Examples

Processes:– A business analyst needs to modify a business process

Rules:– A user needs to add a personal rule to his work list– A business analyst needs to change the rules used as

a condition or lookupWorkflow:

– An administrator needs to change assignment rules or events in a workflow for everyone

– A user wants to specify her notification channel

Design-Time CustomizationInfrastructure for protecting changes across upgrades

Use cases:• Process and Scope level customizations

• Adding New activity in BPEL without new artifacts– e.g. Adding Assign, wait, switch, scope, etc

• Adding New Activity in BPEL with new artifacts– e.g. Adding transform, adding new parternerlink, human task– Note: If patched process also adds same artifact, the

customized artifact would get overwritten

Using Service Data Objects (SDO)

• Specifies a standard data method and can modify business data regardless of how it is physically accessed.

• Fusion Application uses many ADF Objects. Using SDO in SOA allows the developer to share the underlying business data.


Event Scheduling Service (ESS)

• Support for Java, PL/SQL and Binary jobs • Sophisticated Job, Schedule and Resource modeling• Distributed Request processing across an

application server farm• Ability to dedicate hardware resources for

specialized Jobs• Centralized administration with Enterprise Manager

console • Central database based store (MDS) for storing job
