NET MVC" series, we actually have ddd thinking, but not completely to achieve, because not all the good things must be used, or according to the actual situation, DDD in the large system is a very good design idea, This is not to be denied. But depending on the situation, in our small project, our
the objects within the aggregation.
Warehousing (Repository)
Create a repository for each aggregate root object that represents all objects of that type as a collection of conceptual objects, access to the repository through a similar set of interfaces. The point of warehousing is to let developers focus on the domain model logic and hide real data access behind the warehousing interface, which is not the

I have been confused recently. What is the next generation of object-oriented technology? I am very confused. I would like to discuss it with others.
After reading this article and understanding about domain driven design, I think our current programming language really needs
Some improvements. The process from Domain

(Sequence)The greatest value of a domain model is that it provides a common language that links domain experts and technicians;(P2)A model is a form of knowledge. It simplifies the selection of knowledge and provides a purposeful structure;(P33)Object-Oriented Programming is powerful because it is based on the modeling paradigm and provides an implementation method for Model Construction;(P48)
"Learning Domain driven Design (ii) context map and architecture" gives you a general introduction to the concept of context mapping, and a rough introduction to the domain-driven design of the main use of architectural knowledge,

written document is not updated in time, it loses its meaning, please file it. So the written document please keep as concise as possible the text and the diagram is complementary, do not deliberately biased to a certain description. The code is the most real-time and effective description of the model, but it is too biased and detailed, not to be fully understood by the domain experts, even if the domain

idempotent so that the transaction requester generates the transaction ID directly. Note: The order number is not sensitive, so you do not actually need to generate it on the server side. Or, you need an initial virtual order number that prevents "duplicates," and then the server backend can map the build itself, which is fine.This transaction ID is not actually global, if a sends a transaction request to B, and b needs to send a child transaction request to C during processing, B needs to gene
