Need for Fusion

The ERP domain of oracle consist of product lines like CRM, eBusiness and JD Edwards etc, all of which

had been developed separately on different underlying technological architectures with different setup

tooling to enable configuration and customization. Oracle realized it was time to think differently about

enterprise applications. To bring on the same path and seamless connectivity and integration between

them and other third party tool developed the need for birth of Oracle Fusion apps. When Oracle

designed Fusion Applications, Oracle made a huge commitment to develop Fusion in a whole new way

using a user-centric approach. They took the compelling features from E-Business Suite, PeopleSoft,

Hyperion, and JD Edwards and included them in Fusion.

What are Oracle Fusion Apps?

Fusion applications are not built to replace the current application in market. We have seen various

transformations how application has moved from mainframe, Unix to Client-server to web2. Oracle

envisioned a future state - Fusion Apps are a next-generation suite of business applications, built with a

rich client user interface and embedded analytics. The functionality spans finance, human resources,

project management, sales and marketing and supply chain/procurement. Modular components within

the suite can co-exist alongside existing ERP applications.

Oracle Fusion Applications were envisioned and pitched as anEnterprise resource planning suite - a

combination of features and functionalities taken fromOracle E-Business Suite,JD Edwards, PeopleSoft

and Siebel product lines. The suite is built on top of theOracle Fusion Middleware technology stack

which leverages theService-oriented architecture capabilities ofOracle Fusion Architecture.

Oracle Fusion Architecture

Oracle Fusion Architecture (OFA) is a standards-based technology reference architecture or blueprint for

building applications. Note that Oracle Fusion Architecture is not a product, and can be used without

licensing it from Oracle. Many organizations use it to write applications that can run on Oracle Fusion

Middleware or that compliment Oracle Fusion Applications.

Oracle Fusion Applications is built on top of the Oracle Fusion Middleware technology stack usingOracle's Fusion Architecture as blueprint. Oracle Fusion Architecture provides an open architecture

ecosystem, which is service & event- enabled.

Oracle Fusion Architecture is based on the following core principles,

Model Driven

Organizations can enjoy more rapid application development, greater reuse of software

components, and a much simpler maintenance and upgrade process by adopting the model

driven approach.

Key components of model-driven approach include

Visual tools that enable business analysts to effect changes to business processes, business

rules, or event application functionality

A declarative development environmentthat includes tools that understand business language

instead of specialized technical knowledge

Systematic application extensibility to provide underlying applications and the business

processes with a standard mechanism for extensibility and modification

Lifecycle and change management so that any changes in business operations enacted by

business analysts will have simple and effective versions control, change tracking, approval

processes, and testing processes.

Service & Event- enabled:For extensible, modular, flexible applications and processes

Software-as-a-service has long been a goal of the software industry because it offers lower cost,

higher quality, and faster integration. Yet only in recent years, with the development and broad

adoption of key Web services standards, has software-as-a-service become attainable.

Key components of a service- and event-enabled approach include

Enterprise application functionality delivered as Web servicesvirtually any enterprise application

can be designed as a collection of Web services. Thus, Oracle Fusion Applications can expose their

capabilities as services that can run as global standard business processes, or they can be extended

with industry- or process-specific functionality.

Modular application and business process designby creating applications in a modular fashion,business analysts can then use an ever-increasing catalog of process functionality to tailor business

operations as circumstances dictate.

Web services and SOA infrastructureIn order for a service-oriented approach to succeed, the

underlying Web services and SOA infrastructure must be robust, scalable, and secure.

Unified event managementBusinesses must have a standard programmatic method of dealing

with events of all types. This requires a standardized event-driven architecture (EDA) that can be

used by both Oracle Applications and custom or third-party applications or Web services.

Standards-based:Must be open, pluggable in a heterogeneous environment

A vast range of industry standards were adopted as part of fusion middleware.

Web serviceswidely adopted Web services standards such as SOAP, WSDL, and XML have greatly

contributed to the rapid acceleration of adoption of a service-oriented approach to applications and

IT services.

Business processto achieve some level of standardization in business process automation, the

Business Process Execution Language (BPEL) has been developed and is rapidly becoming a key

standard in the definition of an industry-standard approach to creating service-oriented

applications.

IntegrationIntegration standards are emerging both as horizontal specifications, such as OAGIS

and UN/CEFACT, for large scale enterprise application integration, and as industry or functional

specifications such as Rosetta Net (for high tech industry), HL7 (for healthcare), and HR-XML (for

human resources). Oracle provides technology and thought leadership for industry standards

organizations and has an excellent track record for timely adoption of key open standards at many

levels of the technology stack.

Security and identityReliance on security standards such as Secure Socket Layer (SSL), Security

Assertion Markup Language (SAML), and Security Provisioning Markup Language (SPML) ensure thatsecurity and privacy can be both established and verified by internal and external auditors.

Key Technologies used in Fusion

Oracle fusion application is completely developed using fusion middleware 11g on Oracle database 11g.

Technologies used while developing Oracle fusion application are as follows:

Oracle Fusion application Technology Oracle R12 application Technology

Web logic application server BC4J

ADF-Application development

framework

OA Framework

SOA Suite (BPEL, BPM) Workflow

BI publisher XML Publisher

Enterprise Manager Concurrent Program Manager

Oracle Application Development Framework Overview

Organizations are building composite application which interact with each other seamlessly and utilize

service oriented architecture (SOA) principle.

Oracle Application Development Framework is a meta-framework that integrates a mix of sub

framework to provide the key functions for object-relational mapping and other forms of service access,

data bindings, and user interface, along with the functional glue to hold it all together.

Below diagram shows the core technologies available within the overall Model-View-Controller (MVC)

design pattern used by ADF.

Oracle ADF implements the Model-View-Controller design pattern and offers an integrated solution that

covers all the layers of this architecture with solution to such areas as:

It is based on four layers in architecture:

1) Business service layerthis layers handle data from various source from external and internal

system and handle business logic for application

2) Model layer enable the controller and view layer to work with different business services

providing a abstraction layer on top of business services layer.

3) Controller Layerthe control mechanism of process request flow in application

4) View Layerprovide the GUI dynamic user interface in web browser for the application

View Layer:

View Layer provides the view user interface to application. The view layer uses HTML, rich Java

components using java scripts and html tags and its variation to render the user interface. The viewlayer can be web based, client server based or mobile device based implementation.

Controller Layer:

Controller layer controls the applications flow as via get and post request methods. The web pages

composed of dynamic interaction based on users commands. The controller layer manages the flow

between these pages. Different models can be used when building this layer. Oracle ADF use the open

source Struts controller to manage this flow for web application.

Business service layer:

Business service layer manages the interaction with data persistence layer. It provides the services like

transaction management, business logic execution, data persistence etc with the help of java bean, EJB

or oracle ADF business components.

Model Layer:

Model layer connects the business service to objects that uses then in the other layers. ADF provide a

model layer implementation that sits on the top of business services, providing the single interface that

can be used to access any type of business service.

Conclusion

ORACLE ADF makes J2EE development easier via providing a combination of state of the art ADF

technology and easier to use development environment framework like Jdeveloper. It provides a choice

of development strategies and deployment platform. The out of the box implementation of design

patterns and infrastructure code makes it a perfect offering for both new and experienced developers.
