Create verb

Process logic for the Create verb.

Flow

  1. An ItemStore collaboration object is triggered by the receipt of a Retail_Item business object.
  2. The Retail_Item business object is copied into a high-level object called DataStoreRetail_Item. This object is passed into the IBM® WebSphere® Business Integration Data Handler for XML. By default, it contains the application specific information needed by the data handler. The data handler outputs a string, which contains an XML representation of the Retail_Item business object passed into the collaboration object.
  3. The ItemStore collaboration object builds an application specific business object called SerialItem, which includes two attributes:
    • ObjectData, which is set equal to the XML output from the data handler.
    • ObjectKey, which is created from the key information in the Retail_Item business object and the value of the OBJECT_KEY configuration property in the ItemStore collaboration object This attribute holds the unique key used to store the object in the database.
  4. The completed SerialItem is sent to the To port of the ItemStore collaboration object, which is bound to a JDBCConnector. The JDBCConnector uses the application specific information in the SerialItem to store it in the database. If the object already exists in the database, a ServiceCall exception is thrown and the Create operation fails.
    Note: Although multiple objects in the database with identical keys can be created, because the behavior of record retrievals, updates, and deletes is unpredictable, you should avoid the use of non-unique keys.
