Derived Data Attributes

Derived attributes are attributes that are not atomic. Their data can be derived from atomic attributes in the database. Because they are not atomic, they violate the rules of normalization.

Derived attributes fall into these basic types:

  • Summary (aggregate) data
  • Data that can be directly derived from other attributes
