Business Entity contains persistence functionality

Is there a name for the pattern in which business objects contain their own persistence mechanis开发者_如何学Pythonm? For example:

public class Customer
{
    public string Name { get; set; }
    public int Id { get; set; }

    public void Save()
    {
        // save to database
    }
}

I'm not an advocate of this design - I'm just curious if there is a name for it.

Active record pattern
