Object structure services and enterprise services support query operations. An external source can use a service to run a query and to retrieve data from a system. In both cases, the object structure schema defines the XML content for the query request and the query response.
For an object structure that has more than two levels of business objects, the query framework supports the use of business object attributes in the top two levels of the request XML. The query response XML contains all the objects in the object structure.
All system-provided object structures with a Consumed By value of INTEGRATION, support the query operation by default. You can configure an object structure to support the query operation only and no other operations that support updating objects. You can use the Object Structures application to create additional object structures which provide support for the query operation.
