Cloud Integration Hub uses Data Integration synchronization and mapping tasks to publish data from source applications to the Cloud Integration Hub relational publication repository and to consume data from the relational publication repository into target applications.
To use a Data Integration task in a publication, you create a synchronization task or a mapping task in Data Integration before you create the publication. You select the task when you create the publication.
To use a Data Integration task in a subscription, you can use one of the following methods:
•Create a synchronization task or a mapping task in Data Integration before you create the subscription, and select the task when you create the subscription.
•Create a synchronization task when you create the subscription. Cloud Integration Hub saves the task in Data Integration.
Note: Publications and subscriptions that publish and consume data with an API use the Cloud Integration Hub REST APIs. For more information, see Cloud Integration Hub REST APIs.
