Like Karl, I leave them in each class (or table at the database level).
If you are using OpenBase, it defaults a timestamp (_timestamp)
automatically.
Here's the code Karl spoke of. It took me a bit to figure this out when
I first ran into it. The code goes into the class.java file (where
class is the class name). "setLastUpdate" is an example set method in
this class. Your's will be whatever you call it. In this example, the
timestamp gets set when a new object is created using the class
definition. If you then allow the user to edit the object on a web
page, time passes. So the timestamp can be off by the difference in how
long it takes the user to edit and then save the object.
public void awakeFromInsertion(EOEditingContext ec) {
super.awakeFromInsertion(ec);
setLastUpdate(new NSTimestamp());
}

First I want to thank everyone who has replied to my "newbie" thread.
I have now refactored my design to break up my "Project" table to
actually
be three ala Chuck's advice.
My new question is... I like to have audit fields in my databases so
that
every row is stamped with a creation date/user and last mod date/user.
Should I start a separate base object that includes these "audit"
attributes
and then create a corresponding "audit" table in the database? Or,
should
I just leave them as attributes in my classes and just store the
attributes as
columns in the database?
thanks again.
