[Baypiggies] Python ORM?

[Laurence Clark]

So what is the Python version of Hibernate? Or is this the wrong 
question? Do serious Python users believe in relational databases? If 
not what is the preferred persistence solution for a midsize data model 
-- the kind of thing that would use a hundred tables or so in an old 
fashioned client-server database application with a normalized 
relational database.
