-| repository(domain)           | Interfaces (or abstract classes), which define methods for manipulating data without concern for specific database implementations. <br/>By defining this interface, we can decouple database access: the specific details of data access will be done by implementation classes, such as specific implementations using tools like Mongoose, TypeORM, Prisma, and so on. |

+| interface-adapters           | It should not contain complex business logic. <br/>Responsible for receiving and processing requests from clients. These requests are interactions with external systems that need to be converted into operations that conform to the business logic through adapters.<br/>Relies on the Application layer for core business logic, avoiding direct interaction with databases or other external systems. |
+| resolver(interface-adapters) | Handles GraphQL queries and mutations by converting them into calls to the application layer. <br/>Responsible for input validation and response formatting specific to GraphQL.                                                                                                                                                                                                                           |
