Edit Question
Title
Body
I'm building an ORM, and try to find out what the exact responsibilities of each pattern are. Let's say I want to transfer money between two accounts, using the Unit Of Work to manage the updates in a single database transaction. Is the following approach correct? Get them from the Repository Attach them to my Unit Of Work Do the business transaction & commit? Example: from = accountRepository.find(fromAccountId); to = accountRepository.find(toAccountId); unitOfWork.attach(from); unitOfWork.attach(to); unitOfWork.begin(); from.withdraw(amount); to.deposit(amount); unitOfWork.commit(); Should, as in this example, the Unit Of Work and the Repository be used independently, or: Should the Unit Of Work use internally a Repository and have the ability to load objects? ... or should the Repository use internally a Unit Of Work and automatically attach any loaded entity?
