External consistency is a concept in database design that ensures that the data stored in a database reflects the real world it represents. This means that the data must be accurate, up-to-date, and free from inconsistencies. It also means that the data must be consistent with external entities, such as other databases or applications that use the data. External consistency is important because it ensures that the data in the database is reliable and can be used by other systems or applications without errors or inconsistencies. For example, if a database contains customer information, the data must be accurate and up-to-date to ensure that other systems or applications that use the data can do so without issues.
