An example of an AI chatbot conversation about Data Transfer Objects and their purpose in software development.
What are Data Transfer Objects and why are they used?
Data Transfer Objects (DTOs) are simple objects that carry data between processes. They help reduce the number of method calls and improve performance.
Can you give me an example of a Data Transfer Object?
Sure! A DTO for a user might include fields like 'name', 'email', and 'age', allowing you to transfer user data in a single object.
How do DTOs differ from regular objects?
DTOs are specifically designed for data transfer, often without business logic, while regular objects may contain methods and behaviors.
When should I use DTOs in my application?
Use DTOs when you need to transfer data across different layers of your application, especially in distributed systems.
