Take this simple controller where we create a User. In a previous article about MVC, we looked at some of the most common approaches to utilizing ORMs like Sequelize. How do we usually use ORM models in MVC apps?

how Data Mappers can be used to translate to and from DTOs, Domain Entities and ORM models.

approaches to creating repositories and.

how Repositories act as a facade over complex ORM queries.

how DTOs can be used to stabilize an API.

problems that occur when we don't encapsulate ORM data access logic.

This type of logic is called ' Data Access Logic'.įor developers coming from building REST-ful CRUD APIs using MVC without much attention to encapsulating ORM data access logic, you'll learn: NET Domain-Driven Design with C: Problem - Design - Solution McCarthy, Tim on. In DDD, the Repositories, Data Mappers and DTOs are a critical part of the entity lifecycle that enable us to store, reconsitute and delete domain entities. Perhaps one of the hardest aspects towards learning DDD is being able to determine just what that tool is needed for the particular task. Where do you handle handle domain logic? As close to the Entity as possible, otherwise domain services. What's responsible for handling validation logic? Value Objects. In Domain-Driven Design, there's a correct tool for every possible thing that needs to happen in the development of an object-modeled system.
