Model and implementation of the binding model to be based on the reality of business, and the user is not the reality of the business disjointed 2. Acquiring a model-based language that describes the modeled models, such as UML diagrams, business-based terminology, without singularity, in a unified language (understood by both business and developers), means that business people and developers build a bridge of c

For specific needs, please see the previous blog: DDD Domain driven design practice of how to extract the model, the following is a specific entity, aggregation, value object code, do not want to say what is the entity, aggregation and other concepts, believe that the theory of things we have known. I am curious about ddd, not in real project practice, and even d

In the domain layer, you can implement the business logic of the entity and the aggregate root, before implementing the business logic, we first determine some basic behaviors of the entity and the aggregate root, such as judging whether the entities are equal. The implementation of the specific business logic of the domain object, because it involves to interact with the database, so after the realization

I was fortunate to have read many great gods on the realization of DDD, such as the landing of articles, learning more, benefited, in this recommendation: Www.cnblogs.com/hafiz/p/9388334.html78909897Www.cnblogs.com/netfocus/archive/2011/10/10/2204949.html6681253 The following reference to the structure of the official DDD, summed up the relevant experience of predecessors, and then based on their own micro-services and DDD learning and understanding, made a use of springcloud to build the most b

Layered Architecture) The tasks are divided into user interface layer, application layer, domain layer, and infrastructure layer. User Interface Layer: displays information and explains USER commands. Application Layer: defines the tasks to be completed by the software, and directs the objects that express the concept of the domain to solve the problem. The application layer should be as simple as poss

mandatory requirement simplifies the design of the transmission system between the processor and the memory, and improves the Data Reading speed. For example, a processor reads or writes 8 bytes of data at a time starting from an eight-fold address each time it reads/writes memory, if the software can ensure that data of the double type starts from an eight-fold address, it is only required to read or write data of the double type once.Memory Operati
