In OData (Open Data Protocol), an entity is a representation of a data record that typically maps to a row in a database table.

Key Concepts:

Entity = Object or Record
- For example, a Customer, Order, or Product can each be entities.
Entity Type
- Defines the structure of an entity: its properties (fields) and key (unique identifier).

Steps

Expand the Data Model
Right-click Entity Types → Select Create.
Enter:
