Is there any recommended way to get data from ZClass instances to a corresponding RDBMS (Oracle 8i specifically) table?

What I could think of as options are: (I've'nt tried out any!) 1. In manage_add for my Zclass call the corresponding ZSQL insert method - Can this be done? - What can be done for updates? 2. Create masking DTML methods to create Zclass instances dynamically. Call ZSQL methods alongside as well. 3. Do periodic downloads of ZClass instances - say XML format - and batch upload to database.

This sounds like a job for ZPatterns: http://www.zope.org/Members/pje/ZPatterns Most people find ZPatterns a bit difficult to get started with. It is also alpha-release software, so *caveat emptor*. Read the ZPatterns wiki too. http://www.zope.org/Members/pje/Wikis/ZPatterns/HomePage -- Steve Alexander Software Engineer Cat-Box limited http://www.cat-box.net
