VO vs. Entity: Understanding the Difference in Object-Oriented Programming

VO (Value Object) and Entity are two common concepts in object-oriented programming.

'VO is a purely data object, often used to package multiple data fields into a single object for easier transmission and use. VOs are typically read-only, lacking the ability to modify data and shouldn't contain business logic. Their primary purpose is data transfer and encapsulation.

'Entity is an entity object with business logic, representing a real-world entity such as a user, order, or product. Entities encompass data fields, business methods, and logic to describe their behavior and state. Entities are usually read-write, allowing data modification and manipulation.

Therefore, the difference between VO and Entity lies in their purpose and usage scenarios. VO is primarily used for data transfer and encapsulation, while Entity is used to describe the behavior and state of entities.
