Data Items are objects that contain one or more fields of data. Data Items may be stored in collections in your app.

If you are used to use traditional SQL databases you may look at a Data Item as a row in a table in your database.

A data item always belongs to a specific data model (a data model is a definition of the properties the data item should have).
