Yes and no :) It uses sqlalchemy as it's orm, which is quite flexible and allows the use of plain old sql, but you still have to map the result to objects for the GUI to to handle them. You are right that the ORM makes easy things easier, eg. what we do a lot is to create our core model using the ORM, and then create the different summaries directly as views in the database (since these are usually very complex queries, and those tend to be easier to write/debug in plain old sql). Then we use the ORM again to map those views back to objects and have them visualized. Cheers, Erik -- http://mail.python.org/mailman/listinfo/python-list
