Exploring Entity Framework Core on the Query Side

🔍EF Core's query side can be implemented in clean architecture by creating a separate service for reading data.

🔧The IOrderReadService interface can be used to abstract the DB context and provide a layer of isolation.

✨By separating the query logic from the DB context, we achieve greater flexibility and testability.

📚The clean architecture approach helps in decoupling the application from the persistence technology.

⚙️Exposing the DB context in the query side can lead to potential coupling and leakiness in the application.

What is the purpose of the IOrderReadService interface?

—The IOrderReadService interface helps in abstracting the DB context and providing a layer of isolation for the query side of the application.

Why is it important to separate the query logic from the DB context?

—Separating the query logic from the DB context allows for greater flexibility and testability in the application. It also helps in decoupling the application from the persistence technology.

How does clean architecture contribute to the implementation of the query side?

—Clean architecture provides a clear separation of concerns and helps in maintaining a modular and scalable codebase. It allows for the decoupling of the query side from the persistence technology, promoting clean and maintainable code.

What are the potential drawbacks of exposing the DB context in the query side?

—Exposing the DB context in the query side can lead to potential coupling and leakiness in the application. It can also make the application harder to test and maintain as the query logic becomes tightly coupled with the persistence layer.

How can the query side be implemented in a persistence-agnostic manner?

—By creating separate service interfaces, such as IOrderReadService, and abstracting the DB context, the query side can be implemented in a persistence-agnostic manner. This allows for easier switching of persistence technologies without affecting the overall structure of the application.
