Step 2. Define the Resource Mapping

After you define the resource, the Developer tool creates a resource mapping that contains a REST Output transformation. The REST Output transformation structure defines the response message that the web service returns to the client. Add a Read transformation and a Lookup transformation to the mapping.

The following image shows the resource mapping to create:

The mapping contains three transformations, the Read_Customer, the Orders_Lookup, and the Output transformation.

The mapping contains the following objects:

Read_Customer: The Read_Customer transformation reads the customer table. The transformation returns all the customer rows in the table.
Orders_Lookup: The Lookup transformation retrieves the orders for each customer.
Output: The REST Output transformation receives customer information from the Read_Customer transformation. It receives order information from the Orders_Lookup transformation. The REST Output transformation generates a hierarchical JSON file that lists the orders for each customer.

The resource mapping does not contain a Filter transformation to limit the customers to retrieve from the customer table.

The Data Integration Service filters the output data based on any filter in the client request.
