What is Interface repository?
An interface repository is an object implementing the CORBA::Repository interface. The purpose of the interface repository is to maintain type information about IDL files. Once an IDL file is compiled, its definitions can be stored in an interface repository and can be retrieved remotely by other ORBs.
What is the difference between repository and DAO?
DAO is an abstraction of data persistence. However, a repository is an abstraction of a collection of objects. DAO is a lower-level concept, closer to the storage systems. However, a repository is a layer between domains and data access layers, hiding the complexity of collating data and preparing a domain object.
What’s the best way to implement a repository?
As you can see it’s not really important how we implement the repository. What’s important is that all repositories and implementations respect the defined contract (interface) and all posses a GetAll method returning a list of employees. And then you will have a controller which uses this interface.
Why do we use interfaces in the repository pattern?
This allows you to swap out implementations for testing purposes very easily and promotes loose coupling. Just to clarify, there is no link between the use of interfaces and the repository pattern specifically, it is just another pattern that can make use of them.

What happens if an application does not follow the repository pattern?
If an application does not follow the Repository Pattern, it may have the following problems: Difficult to implement database caching, etc. Using the Repository Pattern has many advantages: Your database access code is centrally managed so easy to implement any database access policies, like caching;
When to use domain objects in a repository?
Your repositories should return domain objects and the client of the repository can decide if it needs to do the mapping. By mapping the domain objects to view models (or something else) inside a repository, you prevent the client of your repositories from getting access to the underlying domain object.
