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

1. How to extract models from DDD domain-driven design practices 2. Domain-driven design of DDD: aggregation, entity, and value object In fact, the infrastructure layer mentioned here is only some interfaces and basic classes of t

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

AccountName}, constants.accountindextable); } }Private SqlConnection getconnection () {return new SqlConnection (configsettings.connectionstring); } }}From the above we can know that it uses the data access technology is dapper, not EF, it also has no IQueryable design

Based on the concept of front-facing domain-driven design and some best practices, the domain model is the most central part of the system, and we use the example of the previous sales order, the core construction of this case system starts from the domain layer. The

Unit testing best Practices for domain-driven design (i)After introducing the DDD case, we can finally get to the topic, the test code of this program is based on Xunit, the assertion component is fluentassertions, and similar components have shouldly. In addition, this case uses code contracts for. NET, and if this plugin is not installed, individual tests may n

different angles. New Practice: focus on basic operations. Frequent operation of basic types, especially in different cases, usually means the lack of domain concepts. for example, string type. if you find that you often need to take a certain segment of a string or locate a specific stator string, it is likely that the domain concept is encoded on the string as the implementation. in fact, except f

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

Domain-driven design methods start with modeling. They mainly include information modeling, behavior modeling, and UI modeling; Information modeling is the beginning of a domain-driven design. Information Modeling partitions info
