Description: The mapping layer in databases is responsible for translating between the application’s data model and the database schema. This layer acts as an intermediary that allows developers to interact with the database in a more intuitive way, using objects and data structures that are familiar in the programming context. Instead of having to deal directly with the complexities of storage in databases, developers can define their data models in terms of classes and objects, simplifying the development process. The mapping layer also handles read and write operations, ensuring that data is stored and retrieved efficiently. Additionally, it provides functionalities such as data validation and management of relationships between different entities, which is crucial in more complex applications. In summary, the mapping layer is essential for facilitating interaction between application logic and the database, enabling more agile and less error-prone development.
