[postmodern-devel] dao functionality

Hi everybody, I have decided to use the postmodern library to basically dump and then keep updating a large in memory object database into Postgres. I am coming from the lisp side (my knowledge of rdb is limited). I am wondering if the dao metaclass would allow me to define a table like the 'enemy' example. In particular is it possible to specify :foreign-key? I don't intend to keep my objects in memory using dao class. I just want to use it to create tables and then to do inserts and updates. Should I use S-SQL and sql-compile instead? Thanks, Roman
