<h3>How do derived attributes work?</h3>
A derived attribute is an attribute or property in a table that has been calculated or derived using another attribute used in database management. The information for a derived attribute is obtained from or duplicated from the attributes of another table in the same database. The database does not actually contain them.
An entity relationship model, or ER model, is used to establish the relationships between different entities in a database. The ER model displays the derived attributes as a dashed oval. The name of the derived attribute is contained within the oval.
