The data mapper pattern is often used in applications that require a separation between the domain model and the database. Common use cases include ORM (Object-Relational Mapping) frameworks, data synchronization between different data sources, and complex data transformations.
Can you give me an example of an ORM that uses this pattern?
Sure! One popular example is Hibernate, which is a Java-based ORM framework that uses the data mapper pattern to map Java objects to database tables.
What are the benefits of using the data mapper pattern?
The main benefits include improved separation of concerns, easier testing, and the ability to change the database without affecting the domain model.
Are there any drawbacks to using this pattern?
Yes, some drawbacks include increased complexity and potential performance overhead due to the additional mapping layer.
