[Zope] Re: Zippy, or when to use external database

Hello, If I were to start out designing something like the Zippy package, my first thought would be to enter Zippy's various quotes into a database like MySQL and go from there. It looks like this might not be the best design choice. Can someone describe when it is best to use an external database instead of Zope's(python's) internal persistance? How many Zippy one-liners would there need to be to justify using an external data source? Is it just the size that would necessitate a switch (assuming a single table source - non-relational)? Thanks, erik myllymaki erikm@islandnet.com
