How are multivalued attributes implemented?
Multivalued attributes are implemented as a separate table with a composite key consisting of the entity and attribute value. Conceptual model: Logical model: Physical model: Associative entities are implemented exactly like relationships, since they are in fact just relationships that are the subject of further relationships.

What is an example of a composite attribute?
For example: let us consider a person having multiple phone numbers, emails, and an address. Here, phone number and email are examples of multi-valued attributes and address is an example of the composite attribute, because it can be divided into house number, street, city, and state.

What is the difference between multivalued and composite attributes?
ans. Multivalued attributes in databases have the ability to hold many values for a single entity, such as a contact having multiple phone numbers. Conversely, composite attributes integrate multiple less complex attributes to generate a more intricate one. For example, a full name attribute can be created by merging the first and last names.

What is the difference between simple attributes and composite attributes?
Simple attributes are basic, while composite ones are made up of smaller parts. Derived attributes are calculated from other attributes, multi-valued ones can hold multiple values, and key attributes uniquely identify each entity. These attributes help organize and understand data in a database model.

What is the difference between a multivalued attribute and a materialized attribute?
If materialized, they're indicated as normal columns, and the model can be complemented with triggers or expressions if required. Multivalued attributes are implemented as a separate table with a composite key consisting of the entity and attribute value.
