We have layers like: facade appService domain And We have use Dozer to help us convert entity to dto. But i have 2 question now: from entity to dto we can use dozer, but from dto to entity can we use dozer? If Yes, How? Where shoud i create entity? in facade or DTOAssembler? for example,I have to register a book. the book Entity look's like: Book{ public Book(BookNumber number,String name){ //make sure every book has a business number, //and the number can't change once the

Recently I was learning about ORM (Object Relational Mapping) and the 3 tier architecture style (presentation,business and data persistence ). If I understand correctly, I can separate the data persistence layer into DTO and DAO layer. I would like to understand, how the following parts works together in a data persistence layer. DAL (Data Access Layer) DTO (Data Transfer Object) DAO (Data Access Object) In a top of that I learnt that In larger applications MVC is the presentation tier only of an N-tier architecture. I got really confused, how it can be even possible for example in a 3 tier

Basically, my EDMX file is on my DAL layer. So the UI will have direct access on my DAL. Thanks. 回答1: Basically, I don't think it's a good idea to send DAL objects to your interface, so I would use DTOs. To minimize the effort doing so I would take a look at an DTO generator , to generate DTO code which lets you convert from DAL object to DTO and vice versa. EDIT: Sorry, didn't see you are using POCO.

My domain model has no awareness of my viewmodels so I use automapper to go from viewmodel to entity and vice/versa. When I introduced WCF to my project (a late requirement), I started having to deal with disconnected objects. That is, I retrieve an entity from the database with NHibernate and once that entity is serialized it becomes disconnected and each child collection is loaded regardless of whether or not I plan on using it meaning I'm

However the reply I find mostly is like the one on this question , which is not useful to me as my object is a Data Transfer one and has no physical reference on a database to query for So, I'd like to know if anyone has faced similar issue and what

Also, some DTO s in a separate library, which is shared between Server and Client side. An Aggregate of an entity is more informative than its DTO . So, in order to convert from DTO to Aggregate , a repository should be accessed by a Dto Assembler . Interfaces of repositories are in Domain Layer . That's why i come to conclusion that DtoAssembler should be a part of DomainLayer . Is this right? 回答1: No, this would be plain wrong in the context of DDD. Try asking a (non
