Hi @coder rock,

Please suggest me we are developing an mvc web application and which one is the best

First, the two patterns are not related; the factory pattern is a creation pattern, while the repository pattern is a structural pattern. Factories and repositories work well together.

In some cases you can delegate responsibility for object creation from your repository to your factory classes when you're reconstructing objects from the data store.

client <=> repository -> factory
               |
               v
            database

1. The client requests an object from the repository.
2. The repository queries the database.
3. The repository sends raw data to the factory.
4. The factory returns object.

Depending on your situation, I personally think using repository pattern is enough.

the factory pattern is for configuration and customization, not performance. the most common factory pattern with ado.net is the repository pattern. say you wanted your code to work a relational data like sql, and no-sql like mongo db.

you would define an interface for all the database actions. then you would write an implementation for each database type you wanted to support.

now when you need to create an instance of the repository interface, you need to know the database type desired. here the factory pattern can be used.

IMyRespository repo = MyRespository.Create();

a simple implementation might be:

public class MyRespository
{
     public static IMyRespository Create()
     {
         switch (setting.Type)
         {
            case "MONGODB": return new MongoDBRepo();  
            case "SQL": return new SqlRepo();
            default: throw ...
         }
     }
}
