问题 I used to design my application around anemic domain model, so I had many repository object, which were injected to the big, fat, transaction-aware service layer. This pattern is called Transaction script. It's not considered a good practice since it leads to the procedural code, so I wanted to move forward to the domain driven design. After reading couple of articles on the web, listening to the Chris Richardson's talk on Parleys and reading DDD chapters of the POJOs in Action, I think I got

问题 I'm trying use DDD in an application I'm currently working on. I have a following UserAggregate structure: UserAggregate - ProfileEntity - ImageEntity - RatingEntity And i have a UserRepository which is querying entities mappers to build a UserAggregate. Now I'd like to pass the UserAggregate to the UserRepository for persistance, like UserRepository->save(UserAggregate) . How do I tell the UserRepository that UserAggregate children entities have changed and needs to be saved? Is there any

问题 I'm starting to develop with Fluent NHiberate, and I was wondering how I create a defined 'Foreign Key' relationship in my Mapping class. Here's my class. These classes are a one-to-one with associated tables. public class Song { public virtual int SongID{ get; private set; } //Primary Key public virtual int SongArtistID { get; set; } //Foreign Key mapping to 'Artist.ArtistID' public virtual string Title { get; set; } } public class Artist { public virtual int ArtistID{ get; private set; } /

问题 Lets take a hypothetical project such as a student enrollment system for a music school. Within the system there needs to exist a way to enter student data for a new student interested in receiving instruction at this school and we can assume that students may have access to this functionality through a web site. Part of the enrollment process asks the student the type of instrument for which she would like to receive instruction. As a result of entering information about her preferred

问题 I have a bank account domain as listed below. There can be SavingsAccount, LoanAccount, FixedAccount and so on. One user can have multiple accounts. I need to add a new functionality – get all accounts for a user. Where should be the function written and how? It would be great if the solution follows SOLID principles( Open-Closed principle,…) and DDD. Any refactoring that would make the code better is welcome. Note: The AccountManipulator will be used by a website client over a web service.

问题 Say you were to develop a system which availability of entities and domain logic is highly dependent on user context. Would it make sense to handle the user context sensitivity within repositories by making individual repository instances user context aware? I'm considering adopting this methodology as a way pulling the reliance on user context away from my Entities but I'm not sure whether there are any pitfalls that I may not be aware of with going this direction. The way I'm planning
