Web Oriented Architecture (WOA) and Mobile Oriented Architecture (MOA) are terms coined for the architecture backing modern HTML 5 web applications (rich client/thin server) as well as mobile applications. A pivotal part of WOA and MOA is a layer of services that exposes relevant aspects - both data and functions - of enterprise systems, in a standardized fashion that can easily be consumed. RESTful services using JSON for message payloads are commonly preferred for this. The next generation of the SOA Suite has cloud integration, JSON processing and REST-services as one of its core themes. In this session, we will discuss how a MOA & WOA is designed and how the Oracle SOA Suite & Service Bus - both the current 11g and the upcoming 12c release - can be used to create the services layer.

Challenges and Requirements
for WOA/MOA
• REST & JSON for easy access
• Caching to handle the load and provide 24/7
– availability mismatch between UI and back end
• Filter data - at right level
– data context/authorization
• Minimize number of network requests
– presentation services rather than entity service access)
• Handle Offline/Online synchronization
• Support push notifications
• Personal cloud for user specific data and cross device experience
– Preferences and customizations, search & navigation history, in flight ‘transactions’

17. Summary
• Mobile and Web Oriented Architecture
– Make life easier and scalable on modern UI
• Special challenges on SOA infrastructure
• With Oracle SOA Suite and Service Bus and quite a bit of manual effort,
we can
– Expose and invoke RESTful services
– Deal with JSON data
• SOA Suite 12c adds out of the box, native, declarative support for
– Exposing Services/Pipelines and References/Business Services as RESTful
interfaces and map REST operations to services
– Natively converting between XML and JSON
– Fine grained interaction with the Coherence cache
ServiceBus
