Re: [Zope] trees, SQL and ODB's

I have a database of entries that have a category. Categories can be nested. <snip>

a. I'm using a SQL database to store my categories (each has a category_id and category_parent_id )

I have a little rule of thumb that if your data is tabular, stick it in a RDB, if it's tree-like, stick it in an ODB. cheers, Chris
