Entity Set or Entity Type
- Entity is the fundamental item in any data model.
- An entity is a ‘thing’ or ‘object’ in a real world that can be distinguished from all other objects.
eg:- car, table, book, etc.
- An entity need not be a physical entity, it can also represent a concept in real world.
eg:- project, loan, etc.
- It represents a class of things, not any one instance.
A collection of a similar kind of entities is called an Entity Set or Entity Type.
