2015–6-28 the first chapter is the key factor of effective modeling of knowledge 1. 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

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

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

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

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

In fact, enterprise application architecture is a seemingly simple actually very complex direction, I hope with you to learn together progress, thank you.King Qingyue CultureSource:http://wangqingpei557.blog.51cto.com/This article is copyright to the author

is not possible to create a model that can be used because people who do not understand the technical implementation of the model. Since the concept is after all a concept. Once landed on the code, everything changed in the architecture. It's not that simple and straightforward. Need to take into account reading and writing, business flow, responsibility and so on. There is a very strong technical problem inside.Okay, here's the end of the article. I

A friend asked me how to layer the architecture designed with domain model and what to put in each layer. I think we can use a very simple principle to answer this question, although not necessarily complete and correct: 1. Performance and page-related information are at the presentation layer.2. It is a basic architecture, such as Hibernate encapsulation and
