From a system functionality point of view, derived attribute values is calculated once they are needed to write down reports or invoices.

If an attribute’s value may be derived from the values of other attributes, then the attribute is derivable, and is claimed to be a derived attribute. For instance, if we've got an attribute for invoice date then invoice is derivable. Sometimes an attribute of 1 entity type comes from attributes from other entity types. Consider the attribute for the entire of an Invoice. a price of In Total is derivable; it will be computed from invoice lines. Someone who implements a database and applications that access the database would wish to make a decision whether the worth of a derivable attribute should be computed when the entity is stored or updated versus computing the worth (on-the-fly) when it's needed.

Rich Morin, a senior editor at the Pew Research Center, wrote about a new study on public opinion on Wednesday and found that:
