What is the difference between Data Mapper and Repository patterns?
An example of an AI chatbot conversation about Data Mapper vs Repository patterns in software design.
What is the difference between Data Mapper and Repository patterns?
The Data Mapper pattern separates the in-memory objects from the database, while the Repository pattern acts as a collection of domain objects.
Can you give me an example of when to use each pattern?
Use Data Mapper when you need to decouple your domain model from the database schema. Use Repository when you want to manage collections of domain objects.
What are the advantages of using the Repository pattern?
The Repository pattern provides a more object-oriented approach, simplifies data access, and promotes separation of concerns.
Are there any downsides to using these patterns?
Yes, both patterns can introduce complexity and may lead to performance issues if not implemented carefully.
