Hi,

I'm a student and I have to do a work about Oracle Lite and its Java capabilities. I have got the documentation (Java Developers Guide, ...) but I dont't find this really satisfying as there isn't described how to create constraints, which I finally found out, or how to create relationships.

Concerning the relationships I've got the following problem. I have a class order containing a client as an attribute of the type client which I have previously defined. Now I want to create a relation saying that the client in the order has to be a client already existing in the class client. (In Oracle 8 one can do sth. like this using the "ref" keyword.) My problem is, that in order, the client is an attribute, but the class client is not and I think one can only create a relation between attributes.

How do I do it then? or am I misunderstanding something?

Please cc me as I'm not always on the list.

Thanks,
Marc, Germany
