Implement a Save method for my object

Question

I\'m trying to improve my application\'s design, So instead of calling the DataAccess layer from the presentation layer. I\'ll try to implement a save method from my object

Answer 1

if you follow this pattern you will have the saving logic inside the object definition itself, so when you call from PL:

obj.SaveObject();

this will happen in the Object itself:

public void SaveObject()
{
  DAL.SaveObject(this);
}

and your DAL stays the same as you shown above.

it's a matter of design, I would not put the logic of saving inside the object but I would have a BusinessManager or an ObjectMapper to read from DAL and save to DAL.

in general is a good practice to have read or load and Save in the same place, BusinessObject or BusinessManager, but together so you find them easily and update both in a breeze if you add or change a field.
