DMoz Relational Implementations category: chaff from wheat

        I maintain the
http://dmoz.org./Computers/Software/Databases/Relational category, including the Implementation subcategory.

        It has been a long time since I have wanted to check the 'relationalness' of several listed systems, but haven't neither the time nor the expertise.

        So I would like to ask someone more knowledgeable to take a look and tell me which systems should be considered 'quasi-relational'
-- meaning not relational at all, but at least more interesting than
SQL -- and which should be dumped altogether.

        Any hints accepted, but please justify.

        Thanks in advance.
