[Zope] Design Issues

I'm relatively new to Zope. I've written a couple of SQLMethods using ZODB connections. Currently I've put them in the root directory of Zope. I have questions regarding possibilities and design issues:- 1. Is it possible to create an SQLMethod in a folder if the connection object exists in another folder (the connection object is not available here even through acquisition) ? Experienced zopers : would you do this? 2. Would it be a good idea to define all SQLMethods and corresponding connections at the root ? Then they can be used anywhere. 3. What are the folders under Control Panel:Products etc for ? Would I ever need to 'add' any objects under those folders ? Thanks, Shalabh
