Is Dao same as repository?
DAO is an abstraction of data persistence. However, a repository is an abstraction of a collection of objects. DAO works as a data mapping/access layer, hiding ugly queries. However, a repository is a layer between domains and data access layers, hiding the complexity of collating data and preparing a domain object.
What is difference between DAO and entity?
Remember, a DAO will be a per-table object, whereas a Repository will almost always have to use multiple DAO’s to build a single Entity. If you find that is not the case, that your Repository and Entity only need to access a single table, then you are most likely building an anemic domain.
What do you mean by repository design pattern?
In other words, we can say that a Repository Design Patternacts as a middleman or middle layer between the rest of the application and the data access logic. That means a repository pattern isolates all the data access code from the rest of the application.
How to create a repository in dot net?

Which is repository code should do one thing?
This would leave all of the dependency injection logic in the RepositoryPattern.Data library which could be beneficial, especially if this were a NuGet library or a Git submodule that was being reused across multiple projects. Repository code should do one thing, interface the data provider.
Can a fake repository be used in unit testing?
It’s also very easy to work with unit testing with this pattern because a fake repository can be created and used. The repository interface defines what methods are expected from any repository that derives from this interface.
