A resource includes the mapping that the REST web service runs and the definition of the response message that the web service returns. The resource also includes a resource ID, which is a key field in the output data. You can create a resource from a data object or you can manually define a resource. The Developer tool creates the resource if you deploy an object as a REST web service. A web service can have multiple resources.

A request from a web service client to the web service to perform a task. An Informatica web service can perform an HTTP GET method. The request message is a string that contains the name of the web service, the name and network location of the resource to perform the task, and the parameters to filter the output.

The mapping that returns the data to return to the web service client. You can create a default or a custom resource mapping. A default resource mapping contains a Read transformation and an Output transformation with the same ports. A custom mapping might contain other transformations with the Read transformation and an Output transformation. A custom resource mapping might have a Read transformation with different ports than the Output transformation.

A JSON or XML file that contains the data to return to the web service client. The response message can contain a hierarchy of elements and multiple-occurring data.
