Re: SQL99 - Nested Tables

The way I understand Nested Tables and Object Relational Databases,  
they basically are a layer on top of any old RDBMS that adds ease for  
the user. I personally believe in normalization theory I just don't  
like implementing it to avoid JOIN syntax.

How difficult would it be to implement (for those more familiar with  
the code) to write such a "layer." It could always be a patch until I  
can persuade more people that it's a good idea.
