Explanation

A Data Item is the basic unit of a record, representing the smallest individual field or attribute within a database structure. Data items are the atomic building blocks that define what specific pieces of information can be stored - like a name field, date field, or numeric value. This contrasts with Record Type (the structure definition) or Record Occurrence (the actual instance with values).
