The Adapter for PeopleSoft Enterprise supports
synchronous outbound request processing. Synchronous outbound processing means
that when the client application sends a request in the form of a business
object to the adapter, the adapter processes the request and returns a business
object representing the result of the operation to the client application.
When the adapter receives an inbound business object, the processing flow
is as follows:
- The adapter extracts meta data from the business object that identifies
the appropriate PeopleSoft component interface to access.
- It extracts from the business object the outbound operation to perform.
- Once it accesses the component interface, the adapter sets the keys from
values specified in the business objects.
- The adapter instantiates an existing component interface to retrieve,
update, or create a component interface, and then it populates that component
interface with data from the hierarchy of business objects.
Note: The adapter processes attributes in the order defined
in the business object. For example, if there is a complex attribute between
two simple attributes, the adapter processes the simple attribute at the first
position, then the complex attribute followed by the simple attribute. After
the changes are made, the component interface is saved to commit the data
to the PeopleSoft database. This pattern of processing is used for Create
and Update operations only.
