Pradeep Sahoo · Answer

Repository pattern is to increase testability and have a loose coupling to underlying persistance technology. to make domain object persistance more generic we need to write a layer that is a repository pattern.

Without Repository class mean Which pattern for use on mobile apps

Atul Kumar · Answer

If you are working for mobile apps then you have to write your repository classes around web services. You create a separate project for Class Library using C# which can then be used for multiple projects. You have to make requests to web services and parse data in repository class methods.

Atul Kumar · Answer

Repository is one of the design pattern to structure your data access and manipulation code. You just need to write your own class by following the principles of repository pattern(in any language). Repository pattern is a class which contains all CRUD operations (create read update and delete) which also takes care of database operations like connections commands queries and readers. Code using repository class will only have access to it's read write and delete operations. You can create only one class to take care of all crud operations for multiple table using interfaces. Today's all ORMs like entity framework or n-hibernate follows repository patterns. Please mark as accepted if found helpful
