# Domain
|
||
|
||
> subject area in which we build an application
|
||
|
||
> We have some core domains and some sub domains
|
||
|
||
|
||
> Working out all domains is an iterative process
|
||
|
||
Bounded Context -> Each subdomain has its own bounded context so that they can each have their own "language"
|
||
|
||
Context Map -> outlines which domains communicate with each other and how
|

|
||
Anti-Corruption Level

|
||
Tactical Design
|
||
|
||
|
||
Domain Objects -> 1. Entity Objects 2. Value Objects

## **Solution Name: MyApp (or your project name)**
|
||
|
||
📂 **MyApp.sln** (Solution file)
|
||
|
||
### **1. Presentation Layer** (📂 `MyApp.WebAPI`)
|
||
|
||
- **Purpose:** Exposes the application via a web API.
|
||
|
||
📂 `MyApp.WebAPI`
|
||
- 📂 **Controllers** – Defines API endpoints.
|
||
- 📂 **Middlewares** – Implements custom middleware (logging, exception handling).
|
||
|
||
### Dependencies:
|
||
> Projects: ApplicationProject, DomainProject
|
||
> Packages: AutoMapper, Microsoft.EntityFrameworkCore.Design, Microsoft.EntityFrameworkCore.SqlServer, Microsoft.EntityFrameworkCore.Tools, Newtonsoft.Json
|
||
---
|
||
|
||
### **2. Application Layer** (📂 `MyApp.Application`)
|
||
|
||
- **Purpose:** Contains the application logic, use cases, and service abstractions.
|
||
|
||
📂 `MyApp.Application`
|
||
- 📂 **Interfaces** – Defines services like `IUserService`, `IOrderService`, etc.
|
||
- 📂 **Services** – Defines services like `IUserService`, `IOrderService`, etc.
|
||
- 📂 **DTOs** – Data Transfer Objects for input/output models.
|
||
- 📂 **Mappers** – Maps domain models to DTOs (using AutoMapper or manual mapping).
|
||
- 📂 **Validators** – Contains validation rules using FluentValidation.
|
||
>- 📂 **Queries** – Handles read operations (CQRS pattern).
|
||
>- 📂 **Commands** – Handles write operations (CQRS pattern).
|
||
>- 📂 **Exceptions** – Defines application-layer exceptions.
|
||
>- 📂 **UseCases** – Implements application logic (e.g., `CreateOrderHandler`).
|
||
|
||
### Dependencies:
|
||
>Projects: DomainProjec
|
||
>Packages: AutoMapper, Microsoft.Extensions.DependencyInjection

|
||
|
||
### **3. Core Domain Layer** (📂 `MyApp.Domain`)
|
||
|
||
- **Purpose:** Represents the core business logic and entities without dependencies on infrastructure or frameworks.
|
||
|
||
📂 `MyApp.Domain`
|
||
|
||
- 📂 **Aggregates** – Groups related entities following DDD principles.
|
||
- 📂 **Framework** - **Interfaces** – Contains domain-level abstractions like repository interfaces and entity interface.
|
||
- 📂 **Framework** - **Interfaces** – **Repositories**
|
||
- 📂 **Framework** - **Base**
|
||
- 📂 **Enums** – Defines domain-specific enumerations.
|
||
- 📂 **Factories**
|
||
>- 📂 **ValueObjects** – Defines immutable objects that don’t have an identity.
|
||
>- 📂 **Exceptions** – Custom exceptions related to domain logic.
|
||
>- 📂 **Specifications** – Encapsulates domain rules and query logic.
|
||
|
||
### Dependencies:
|
||
>Packages: Microsoft.Extensions.DependencyInjection

|
||
|
||
### **4. Infrastructure Layer** (📂 `MyApp.Infrastructure`)
|
||
|
||
- **Purpose:** Implements external dependencies such as databases, logging, APIs, and caching.
|
||
|
||
📂 `MyApp.Infrastructure`
|
||
|
||
- 📂 **Framework** - **Base** – Implements `IRepository<TEntity>` for data access.
|
||
- 📂 **Configurations** – Stores EF Core entity configurations.
|
||
- 📂 **Services** - Repositories
|
||
- 📂 **Migrations** - Auto Created
|
||
- **DB-Context**
|
||
>- 📂 **Persistence** – Implements repositories and EF Core DbContext.
|
||
>- 📂 **Logging** – Implements logging strategies (e.g., Serilog, NLog).
|
||
>- 📂 **Identity** – Manages authentication and authorization.
|
||
>- 📂 **Caching** – Implements caching strategies (Redis, MemoryCache).
|
||
>- 📂 **Email** – Handles email services (SMTP, SendGrid).
|
||
>- 📂 **ExternalServices** – Integrations with third-party APIs.
