A data object is defined as a coherent, self-contained piece of information suitable for automated processing.

An application function operates on a data object.

A data object may be communicated via interactions and used or produced by application services.

The name of a data object should preferably be a noun. It should be a useful, self-contained piece of information with a clear meaning to the business, not just to the application level.
