The correct answer, at least in some cases, is don't use objects in the first place. That at least fits my interpretation of what Fowler meant by "use the relational model in memory," though--if you're using a relational database, don't try to directly map objects to relational tables, but take advantage of what SQL offers instead. That's consistent with not using objects in the first place (although I suppose it doesn't require it).
