data element

The fundamental data structure in a data processing system. Any unit of data defined for processing is a data element; for example, ACCOUNT NUMBER, NAME, ADDRESS and CITY. A data element is defined by size (in characters) and type (alphanumeric, numeric only, true/false, date, etc.). A specific set of values or range of values may also be part of the definition.

Technically, a data element is a logical definition of data, whereas a field is the physical unit of storage in a record. For example, the data element ACCOUNT NUMBER, which exists only once, is stored in the ACCOUNT NUMBER field in each customer record and in the ACCOUNT NUMBER field in each order record. See field.


The Basic Unit of Storage
Technically, data elements describe the logical unit of data, fields are the actual storage units, and data items are the individual instances of the data elements as in this example. In practice, all three terms may be used interchangeably. However, technical documentation on database management should employ the terms properly.
