design pattern

1. DTO

• Data Transfer (value) Object (DTO)

  
  
• While transferring huge amount of data or values between two layers of application instead of sending between two layer multiple number of time it is recommended to combine all these multiple values into single object and send that object to destination layer
• due to this round trips between layers "sending and receiving values will become easy"
•  jpa or persistence annotations are not required on the attributes of DTO as dtos are not to be persisted
• java-difference-between-entity-and-dto
