    I believe you means that Data transfer objects and Value objects are the same, but the original question was if the Value Object and Data Access Object are the same. I believe they are not. DAO is is used for the access to a persistent data store, and can use DTO/VO for transferring the data to the application.

    They are definitely not the same.
    Value object is just a representation of is same as a normal class with just getter methods inside it.
    Data Access Objects are used to deal with database. You use Value Objects in Data Access Objects in order to represent the data which you have fetched from database.
