By delegating specific
implementation of business logic to a separate system, you can ensure that all
applications that require this logic do so consistently, and you can point to the specifics
in the standard implementation to satisfy audit requirements.
The Oracle Business Rules component of Oracle Application Server combines a Rule
Authoring tool (which lets users create rules using English-like syntax), a Rules
Engine (which executes the called rules), and a Rules SDK (for programmatic access
to rules and the rules repository).

Enterprise Service Bus
In order for an SOA solution to work, all the services must be able to communicate
freely with each other. This simple task is complicated by multiple communications
protocols and the need to connect the service descriptions (in Web Services Definition
Language, or WSDL) between all the players in the environment.
Oracle??™s Enterprise Service Bus (ESB) provides this capability and more. The ESB
also delivers the ability to transform messages and data between consumers using
Oracle Adapters (explained below) to connect to hundreds of data sources, model
interactions between service providers, and implement efficient message routing and
monitoring in the runtime environment.
