oop - Object Oriented Programming - Best Practice?

Question

Which of the following would you go with? And based on object oriented programming which one is the best practice?

A

Class Note
{
    //Some properties, etc
    public static Note getNoteFromServer();
    public void UpdateNoteOnServer();
}

B

Class Note
{
    //Some properties, etc
}

Class NoteManager
{
    public static Note getNoteFromServer();
    public static UpdateNoteOnServer(Note);
}

Answer 1

I would say option B. In that way you separate concerns: you have a Note that can be reused anywhere (and not necessarily on a networked application), and you have a manager class that only cares with server communication.

You may also think on implement logic for multiple servers. For example, you may want to comunicate with data formats like JSON or XML. You may implement an interface (example, interface INoteManager) and then implement two classes with servers for each of the data types I mentioned (example, NoteManagerXml and NoteManagerJson).

The main point on this question is sepration of concerns. Hope I've helped! :)
