The global var, is the best thing to do because they are not using much space
(like the properties does with a lot of script - get then set, not good for the
coder at all). Maybe they(properties) are good in some VERY particular(i dont
really know them) cases but not in all. I think with global var you maintain a
lighter and easier code.

public class Person
{
    private string name = "";
    private DateTime birth = DateTime.Now;
    private int age = 0;
    private bool modified = false;

    public string Name 
    {   //Additionally a if clause to check a valid value might be interesting for user inputs
        set{ this.name = value;
             this.modified = true;
        }
        get{ return this.name; }
    }
    //And so on till modified
    
    //Because of this i never ever can make a mistake where i cange this value outside of the class
    public bool Modified
    {
        get{ return this.modified; }
    }

    //Method for saving itself to database
    public bool SaveYourSelf()
    {
        //Save your self to database
        if(//Command was successfull//)
        {
            this.modified = false;
        }
    }
}
//Another class that checks if Person was modified

public class AnotherClass
{
    public void checkPersonModified()
    {
        if (p.Modified)
        {
            //Do operations, save to database
        }
    }
}
