Difference between Value Object pattern and Data Transfer pattern

Question

In which scenario can I use those design patterns in n-tier architecture?

Answer 1

Data Transfer Object is used to set property values which is coming from database in Data Access Layer (DAO), whereas using VO pattern we can set values in controller layer of MVC that are already set in DAO Layer. Client can have access to VO objects rather than DTO's which he/she can iterate in jsp page. You can say there is a separation of concern for both layers.
