In database applications, an external interface is a defined process and data structure
used to exchange data with other systems. For example, an order processing application
may have an interface to exchange data with an external accounting system.
EXTERNAL INTERFACE COMPLEXITY
The level of complexity associated with an external interface. A simple interface is
generally unidirectional, with limited, stable logic defining the structure of the exchanged
data. A standard export from a database to a spreadsheet is considered a simple
interface. A complex interface may be bi-directional, or may have extensive, adaptive
logic defining the structure of the exchanged data. The transmission of labor data to a
corporate payroll system, with its attendant validation and transaction confirmationrequirements, is considered a complex interface.
