How to Represent Enum Types and Relationships in Oracle

Hi, I'm developing a object database in Oracle 8 but am having a few problems represents enumeration types and relationships.

I have used the ODBMG schema for a logical model and have the following:-

        attribute enum credit-rating{poor,normal,good) credit-rating;

and relationships of the type

        relationship set<order> placed by inverse order::places;
        relationship customer places inverse customer::placed by;

how do I implement these in Oracle 8, there seems to be no obvious on-line help, which is strange?

Thanks.
