- 8. Summary & Resources 1) Use the Repository Design Pattern Decouple the data layer from the business logic. 2) Follow the Don’t Repeat Yourself principle Make sure your CRUD operations are available to use across the application. 3) Follow the Dependency Inversion principle (and SOLID in general) Make sure you can switch your data layer easily. Today you want to use Eloquent with MySQL, Tomorrow you will have to switch to MongoDB.
