IOC are at the class level, but what about database conflicts?

- by mrblah

With IOC I understand you can substitue implementations out by merely editing a configuration file etc. BUT, what happens when the classes are married to particular database tables and sprocs, you can't just swap out an implementation since the classes/entities are tied to particular tables and stored procedures. Am I right here?

Is this basically what an IOC like NInject does?

- by mrblah

Normally I would do this: public class DBFactory { public UserDAO GetUserDao() { return new UserDao(); } } Where UserDao being the concrete implementation of IUserDao. So now my code will be littered with: DBFactory factory = new DBFactory(); IUserDao userDao = factory.GetUserDao(); User user = userDao.GetById(1); Now if I wanted to swap implementaitons, I would have to go to my DBFactory and change my code to call a different implementation. Now if I used NINject, I would bind the specific implementation on application startup, or via a config file. (or bind based on specific parameters etc. etc.). Is that all there is too it? Or is there more? (reason I am asking if I want to know how it will help me here: http://stackoverflow.com/questions/1930328/help-designing-a-order-manager-class)

Help in restructuring a project

- by mrblah

I have a commerce application, asp.net mvc. I want it to be extensible in the sense others can create other payment providers, as long as they adhere to the interfaces. /blah.core /blah.web /blah.Authorize.net (Implementation of a payment provider using interfaces Ipaymentconfig and paymentdata class) Now the problem is this: /blah.core - PaymentData /blah.core.interfaces - IPaymentConfig where Payment Data looks like: using blah.core; public class PaymentData { public Order Order {get;set;} } IPayment data contains classes from blah.core like the Order class. Now I want to use the actual Authorize.net implementation, so when I tried to reference it in the blah.core project I got a circular dependency error. How could I solve this problem? Many have said to break out the interfaces into their own project, but the problem is PaymentData references entities that are found in blah.core also, so there doesn't seem to be a way around this (in my head anyhow). How can I redesign this?
