Once you specify a given type of object, will its schema always remain the same? If so, you should be able to dynamically generate the DAL table definition and have the DAL create the table. However, if you need to make arbitrary dynamic changes to the schema within a given class of object, you're probably better off with a document database like MongoDB. The DAL does have an experimental MongoDB adapter, but I'm not sure how complete it is and whether it could easily handle this use case -- if not, though, I think MongoDB is fairly easy to work with natively via the Python driver.
