What are the best practices in designing a service layer?

Some best practices include keeping the service layer thin, ensuring separation of concerns, and using clear interfaces.

A thin service layer means it should primarily handle business logic and delegate tasks to other layers, avoiding unnecessary complexity.

What are some common mistakes to avoid in a service layer?

Common mistakes include tightly coupling the service layer with the data access layer and not properly handling exceptions.

How do I ensure separation of concerns in my service layer?

You can ensure separation of concerns by clearly defining the responsibilities of each layer and using interfaces to communicate between them.
