Personally I have been using web2py's DAL. Other than form generator availability, 'print as raw SQL', multiple primary keys, widgets*, `check` conditions and compatibility with OracleDB, Postgres, SQLite and some of the NoSQL systems; what else should I be looking for? Thanks for all suggestions, Alec Taylor *not sure if widgets should be a requirement; by widgets I mean annotation of db schema to specify which widget to use with the form generator PS: Will likely use this ORM with: Flask, Bottle or Twisted Matrix
