Description: The logic layer in software architecture is a fundamental component responsible for managing the business logic of an application. This layer acts as an intermediary between the user interface and the database, processing user requests and applying the necessary business rules to transform that data into useful information. Its main goal is to ensure that the application’s logic is separated from presentation and data access, allowing for greater flexibility and maintainability of the software. By implementing this layer, developers can make changes to the business logic without affecting the user interface or data structure, thus facilitating agile development and adaptation to new requirements. Additionally, the logic layer can include validations, calculations, and transaction management, ensuring that operations are performed consistently and securely. In the context of Behavior Driven Development (BDD), this layer becomes a key element, as it allows tests to focus on the expected behavior of the system, ensuring that the implemented logic meets the specifications defined in the test scenarios.
