Drew, I don't want to seem argumentative, but what definitions are you using here? Free floating procedures can provide encapsulation by having a well-defined interface to hide the implementation details. Having them associated with a particular class is another matter. Here the definition of encapsulation is referring to the ability to have a well-defined interface and hide implementation details - something which non-OO languages, such as C or Pascal can also provide. If this is supported in Oracle and SQL3, etc., then it does support encapsulation, albeit not in the OO-sense (i.e. not having a "method" associated with a particular class).
