What is data mapper architecture?
Data mapper architecture is a design pattern that separates the in-memory objects from the database. It allows for a clean separation of concerns.
How does it differ from Active Record?
Unlike Active Record, which combines data access and business logic, data mappers keep these concerns separate, promoting better organization.
Can you give an example of where it's used?
Sure! It's commonly used in applications that require complex data interactions, like enterprise-level systems or applications with multiple data sources.
What are the benefits of using data mapper architecture?
The main benefits include improved testability, flexibility in changing the database, and better adherence to the Single Responsibility Principle.
