smartadmin.core.urf offers a complete, modular and layered software architecture based on Domain Driven Design principles and patterns. It also provides the necessary infrastructure to implement this architecture, focusing on the core of the business Demand, reduce duplication coding, allow junior programmers to develop professional and beautiful Web applications
Domain-driven design (DDD) is the concept that the structure and language of software code (class names, class methods, class variables) should match the business domain. For example, if a software processes loan applications, it might have classes such as LoanApplication and Customer, and methods such as AcceptOffer and Withdraw. DDD connects the implementation to an evolving model. Domain-driven design is predicated on the following goals:
- placing the project's primary focus on the core domain and domain logic;
- basing complex designs on a model of the domain;
- initiating a creative collaboration between technical and domain experts to iteratively refine a conceptual model that addresses particular domain problems.。

Please give me Star if you like it. Every Star is a motivation to encourage me to continue updating.
smartadmin.core.urf follow the DDD design pattern to implement the four-layer model of the application
- Presentation Layer：This layer is the part where interaction with external systems happens. This layer is the gateway to the effects that a human, an application or a message will have on the domain. Requests will be accepted from this layer and the response will be shaped in this layer and displayed to the user.the project use SmartAdmin - Responsive WebApp and Jquery EasyUI
- Application Layer：It is the layer where business process flows are handled. The capabilities of the application can be observed in this layer. Domain entities are created and subject to update here. Depending on the usage scenarios, topics such as transaction management are also resolved here. In this layer, execution of work commands and reactions to domain events are coded. The code snippet for handling the CreateUser work command is given below as an example. In this example, by creating an object of User that comes from the Domain Layer and storing this object in the data storage, request for user creation is resolved. the project：StartAdmin.Service.csproj
- Domain Layer：This will be the core of the application. It is the layer where all business rules related to the problem to be solved are included. In this layer; entities, value objects, aggregates, factories and interfaces will take place. This layer should be kept away from dependencies as much as possible. Third party libraries should not be added as much as possible, as it should not take other layers as a reference.the project use EntityFrmework Core Code-first and Repository Implement. the project：StartAdmin.Domain.csproj
- Infrastructure Layer：This layer will be the layer that accesses external services such as database, messaging systems and email services. The IUserRepository interface designed in the domain layer and used in the application layer will be implemented in this layer and gain an identity.the project use:Nlog,service discovery：Swagger UI,EventBus:dotnetcore/CAP,Authentication and Authorization:Microsoft.AspNetCore.Identity,etc.
-
Domain Layer
- Entities are one of the core concepts of DDD (Domain Driven Design). Eric Evans describe it as "An object that is not fundamentally defined by its attributes, but rather by a thread of continuity and identity，it still follows some good practices：
- Entity:(SmartAdmin.Entity.csproj)
- Inherit a base class "Entity",Add necessary audit classes such as: creation time, last modification time, etc.
- There must be a primary key, preferably GRUID (composite primary key is not recommended), but this project uses an incremental int type
- The field should not be too redundant, you can define the association relationship
- Use virtual keywords as much as possible for field properties and methods. Some ORM and dynamic proxy tools require
- Repositories: wrapper basic data operation method (CRUD),the Project URF.Core
-
Application Layer
- Application Services：Application services are used to implement the use cases of an application. They are used to expose domain logic to the presentation layer.the project:SmartAdmin.Service.csproj
- Data Transfer Objects：Data Transfer Objects (DTO) are used to transfer data between the Application Layer and the Presentation Layer or other type of clients.Typically, an application service is called from the presentation layer (optionally) with a DTO as the parameter. It uses domain objects to perform some specific business logic and (optionally) returns a DTO back to the presentation layer. Thus, the presentation layer is completely isolated from domain layer.the project：(SmartAdmin.Dto.csproj)
- Unit of work:Unit Of Work (UOW) implementation provides an abstraction and control on a database connection and transaction scope in an application.the project URF.Core
-
Infrastructure
- UI Layerout config:Choose a variety of page display modes according to user preferences
- Multi-Tenant： Global Filter of EntityFrmework Core
- Account: Maintenance of login system account, registration, logout, lock, unlock, reset password, import, export and other functions
- Role：Microsoft Identity server
- Navigation menu：System navigation bar configuration
- Role authorization：Configure the menu that the role displays
- Key-value configuration：Common data dictionary maintenance
- Import & export configuration：Excel import and export to make a configurable feature
- Logging：asp.net core logging and Nlog
- Message publish-subscribe：CAP distributed event bus
- WebApi: Swagger UI Api
- CAP： CAP
