[Zope] Newbie: Design considerations

Hi, Question 1: I have to build an application which interacts with an Oracle backend, and I wonder if anyone can suggest some pros and cons of these options: a. Protype app in Python, using the python DB-API - and then deploy with a web front end in Zope, using the object publisher to call the python methods. b. Develop Zope application using ZSQL, et c. Question 2: Is it possible to build a python app which interacts with ZSQL methods? Thanks for your comments. Chui Tey
