Firstly, the performance question of retrieving data from server is put forward by multiple fine-grained network call in multi-tier software system. And the how to use inter-tier data transfer object in EJB design patterns is discussed to solve the question in J2EE. At last, the benefits of choosing this design pattern can quickly organize the project team and make the application to have better performance of data transfer, as soon as data arrives client in this pattern, the data could be stale, so designer should use version number pattern to cooperate to solve it.
