Want to know domain driven design example? we have a huge selection of domain driven design example information on alibabacloud.com
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

Value.dispose (); Orderdbcontext. Dispose (); Base. Dispose (); } }}2. Then we want to implement warehousing, warehousing, mainly for object creation, reconstruction, update and destruction, which create, update and destroy through the
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
some of the concepts in domain-driven design: Repository, Domain,valueobject and so on. But beginners may come to the wrong conclusion: Some people mistakenly think that adding ***repository,***domain,***valueobject into the project architecture becomes the DDD architecture
1. Description of Domain Modeling Domain Modeling is not a new concept. Domain Modeling expert Eric Evans has started using domain driven design since he published domain
for many people in the field-driven design, which mentions some of the concepts in domain-driven design: Repository, Domain,valueobject and so on. But this book also gives beginners a false hint: Some people mistakenly think that
In reality, we encounter a variety of complex scenarios, "there is not a right-way" to describe the API design method is more appropriate, there is no one API design to deal with all scenarios. Unlike "Consumer-driven contract", this article describes another way to design an API:
04 years later, few people can understand this idea through the Internet and English documents. Think about the process we developed before. Basically, after the requirement is divided, we start to create a data table, then create a data model based on the data table fields, and then start to write the data persistence layer, logic layer and UI Layer. I think most people should have such experiences. This development idea is a typical data-centric development idea, and the important busines
domain layer, and begins to record some system-based functions, such as logs, event traceability. 3. domain Domain layer. Domain-driven design is the most central part, can be broken down into the aggregation of roots, entities,
. The domain model is actually a common language for communication between domain experts and analysts and developers. The essence of domain-driven design is "to digest a large amount of knowledge, and finally generate a model that reflects deep-level
model to the data model. EF not only supports generating database DDL from the domain model, but also supports generating the "Domain Model" from the database structure ". I think the latter can be removed, because what we get from the database is no longer a domain model. You will ask why, I can tell you, there is no way to describe the concept of a

AspNetCore-Based Domain-driven rapid development template project, aspnetcore Template AspNetCore has been paying attention to since its release. It has used its spare time to write a project template for rapid development of the project, which has been hosted on github. If you want to directly view the source code, please stamp it below Https://github.com/huanent/WebApi Next I will introduce the details of
Domain-driven developmentObject-oriented methods are considered to be an important improvement in software technology, especially in the modeling of complex phenomena, which is easier than the predecessor. However, the expected progress has not been achieved in terms of reusability, maintainability, reliability, and performance. As a reusable unit, objects are proven to be too small, the framework seems to
these interfaces. A relational database is used as the shared storage of data. Use the most automatic UI structure and the visualized programming tools available. It's just a few minutes away! (Currently popular, including those advocated in this book) truth is that the domain and UI should be separated. Therefore, in the context of domain-driven
structure. I think the latter can be removed because the database is not a domain model. You will ask why, I can tell you, pure data is no way to describe the domain concept. For example: There is a table in your database called "customer", and when you generate a "domain model" from the database structure, Visual Stu
Today, I will take the time to write my series related to the domain-driven design.ArticleSummarized here for your convenience. Based on the writing progress, this list will be updated occasionally. Stay tuned! Entity Framework-driven design practices Entityframework-Domai
Detailed Explanation: https://study.163.com/course/introduction/1005643030.htm?share=1shareId=1142344671Content: Step by step to build a practical project development framework based on the domain Driven Design (DDD) development model. A better understanding of domain-driven
objects and domain services in the following cases. Application Layer: This layer does not contain any domain logic, but it coordinates tasks and maintains the state of the application. Therefore, it focuses more on flow. In the practice of drive design in some fields, it will also be called the "workflow layer ". The application layer is the most controversial
developers to forcibly specify an id value here. In fact ,. every entity in the net object framework inherits from the entityobject class, and this class has an entitykey attribute, which is used as the object key, therefore, the ID value here must be maintained by the persistence mechanism. We can also see that the entity in the domain-driven design has two ide
