Publications and subscriptions control the data and file flow and the schedule of data and file publication or data and file consumption. An application can be a publisher and a subscriber. Multiple applications can publish to the same topic. Multiple applications can consume data or files from the same topic.

Publications and subscriptions can publish from and subscribe to any type of source and target that

Informatica Intelligent Cloud Services

supports. You can publish from and subscribe to different sources of data and files. Because the publishing process and the consuming process are completely decoupled, the publishing source and the consuming target do not have to be of the same data or file type. For example, you can publish data from a file and consume it into a database.

Publications and subscriptions can publish and consume data or files by triggering a
