Is using the following akin to using the unit of work pattern

Does using an nHiberbnate session/transaction combo perform the same function that the unit of work pattern would? below is some code found on the web..

using (var session = sessionFactory.OpenSession())
  {
    using (var transaction = session.BeginTransaction())
    {
      // create a couple of Stores each with some Products and Employees
      var barginBasin = new Store { Name = "Bargin Basin" };
      var superMart = new Store { Name = "SuperMart" };

      var potatoes = new Product { Name = "Potatoes", Price = 3.60 };
      var fish = new Product { Name = "Fish", Price = 4.49 };
      var milk = new Product { Name = "Milk", Price = 0.79 };
      var bread = new Product { Name = "Bread", Price = 1.29 };
      var cheese = new Product { Name = "Cheese", Price = 2.10 };
      var waffles = new Product { Name = "Waffles", Price = 2.41 };

      var daisy = new Employee { FirstName = "Daisy", LastName = "Harrison" };
      var jack = new Employee { FirstName = "Jack", LastName = "Torrance" };
      var sue = new Employee { FirstName = "Sue", LastName = "Walkters" };
      var bill = new Employee { FirstName = "Bill", LastName = "Taft" };
      var joan = new Employee { FirstName = "Joan", LastName = "Pope" };

      // add products to the stores, there's some crossover in the products in each
      // store, because the store-product relationship is many-to-many
      AddProductsToStore(barginBasin, potatoes, fish, milk, bread, cheese);
      AddProductsToStore(superMart, bread, cheese, waffles);

      // add employees to the stores, this relationship is a one-to-many, so one
      // employee can only work at one store at a time
      AddEmployeesToStore(barginBasin, daisy, jack, sue);
      AddEmployeesToStore(superMart, bill, joan);

      // save both stores, this saves everything else via cascading
      session.SaveOrUpdate(barginBasin);
      session.SaveOrUp开发者_开发百科date(superMart);

      transaction.Commit();
    }
  }
}

Martin Fowler:

Maintains a list of objects affected by a business transaction and coordinates the writing out of changes and the resolution of concurrency problems.

Yes the NH session is an example of a unit of work.

Not necessarily. unitofwork.Start() may contain following

1. Open Session
2. Do some initialization (eg.add filters)
3. Begin Transaction

unitofwork.end() may contain following

1.Commit or rollback transaction 2.End session
