The unit of work pattern wraps a set of database operations in a transaction. 

 

'Get the current instance of the helper

Dim db As IDataHelper = DataHelper.SessionFactory()

　　

Using TempUnitOfWork As UnitOfWork = New UnitOfWork(db)

db.ExecuteNonQuery("INSERT INTO Customers (FirstName,LastName) VALUES ('John','Smith')")

db.ExecuteNonQuery("INSERT INTO Customers (FirstName,LastName) VALUES ('John','Doe')")

End Using
