Joe Celko has an approach for handling trees in SQL. It is more difficult than in a network model since elements in a tree form an ordered set, while the Relational model deals with unordered sets. But if that's your only flaw for Relational model, that's a pretty weak arguement.

I've never done Nueral nets, but I was told once it is implemented with a set of weighting tables. Maybe that is an old approach. While that may be your primary purpose, your comments about the Relational model being outdated were not limited to that specific application area. So it again goes back to my comment about how your present your argument.
