Entities and attributes
Entities
In database design, entities represent what will become tables during implementation.
The term 'entity' is used to describe the following:
- a person
- a place
- an object
- a thing
Entities are made up of many attributes.
Attributes
Attributes are the specific characteristics of an entity. Attributes will become fields during implementation.
As an example, an entity to store information on a country may include the following attributes:
- name
- population
- continent
- GDP
- area
- currency
