Show your declarations (don't forget type bodies when there are methods) and the successful compilation of the declarations. Remember that the slash is needed to cause compilation.
Note that it is possible for one relation to satisfy all these conditions. Write INSERT statements to populate your new relations from the data in the original relations of your PDA. Show the correct compilation of your declaration and correct execution of your insertion statements.
Aside: The most recent release of the Oracle loader allows object-relations to be populated directly. However, this loader is not yet running at Stanford, so we have to populate object-relations in this kludgy way.
