-- Explain the concepts of Entity and Attribute
-- In the relational data model, an entity is represented as a record in an entity set. In the relational data model, a field represents an attribute.
-- ref : https://binaryterms.com/difference-between-entity-and-attribute-in-database.html#:~:text=An%20entity%20is%20a%20distinguishable,a%20field%20represents%20an%20attribute.

-- Give examples representing multivalued and derived attribute
-- multivalued attribute : An attribute that can have multiple values for an entity. for Example User entity in an ecommerce have attributes email, password, phone, and address. The address attributes may have multiple value, because a user may have multiple address.
-- derived attribute : An attribute that can be derived from another attribute, for Example age attribute can be delivered from birthdate attribute.
