Regarding Class Design in 1Z0-865 (Assignment)

[Patel Ashish]

Dear Team,

I am working on 1z0-865 exam. Few queries regarding class diagram contents.

1) If DTO and Entity have same attributes then is it really required to show in class diagram ?
For Example - From servlet to EJB , I am passing DTO object and from Bean to DAO , I am passing entity object to persist in database using JPA.

Difference between DTO and Entity :
All entity classes having  @Entity annotation and related onetomany or manytoone or onetoone relationship.
Attributes level , both are same.

I am using UML compliance free product to design Class Diagram for complete system.

Can we show only Class diagram empty box with <<Entity>>EntityName instead of showing all attributes with mapping ? with one note in box like attributes are same as DTO.

Looking forward to your prompt response.

Regards,
Ashish
