I have a question: Will ZODB have something like OQL? The problem in using ZODB is to do simple queries and link different class object instances in queries (SQL join). It is hard to do simple things in ZODB like aggregate functions (sum, max ...) That's why I use an external RDBMS...

The XPath and XQuery support that ought to be coming along with the new XML support will handle this, although not with OQL as such. The functionality will be about equivalent, though. http://www.zope.org/Wikis/zope-xml/XPath%20in%20Zope -- Steve Alexander Software Engineer Cat-Box limited http://www.cat-box.net
