Web Services in Oracle Data Integrator

It shows a simple example with the Data Services, Run-Time Web services (Public Web Service and Agent Web Service) and the OdiInvokeWebService tool.
The Data Services and Run-Time Web Services components are invoked by a third-party application, whereas the OdiInvokeWebService tool invokes a third-party Web service:

• The Data Services provides access to data in data stores (both source and target data stores), as well as changes trapped by the Changed Data Capture framework. This web service is generated by Oracle Data Integrator and deployed in a Java EE application server.
  
• The Public Web Service connects to the repository to retrieve a list of context and scenarios. This web service is deployed in a Java EE application server.
  
• The Agent Web Service commands the Oracle Data Integrator Agent to start and monitor a scenario and to restart a session. Note that this web service is built-in the Java EE or Standalone Agent.
  
• The OdiInvokeWebService tool is used in a package and invokes a specific operation on a port of the third-party Web service, for example to trigger a BPEL process.
  

Oracle Data Integrator Run-Time Web services and Data Services are two different types of Web services. Oracle Data Integrator Run-Time Web services enable you to access the Oracle Data Integrator features through Web services, whereas the Data Services are generated by Oracle Data Integrator to give you access to your data through Web services.
