Greetings, I'm not sure whether or not to use an external database (mySQL) for my site. I can envision, for example, having a folder, 'reports', that contains 100,000 reports. Each report is either a folder or a dtml-document with a 'client' property. I would use some dtml to go thru all of the reports and list those that belong to the currentClient: <dtml-in "reports.objectValues()"> <dtml-if "client == currentClient"> <dtml-var sequence-item> </dtml-if> </dtml-in> Or, I can do this using mySQL. If Zope's database is capable of scaling this large, I'd rather use it. Any thoughts? Thanks, Steve
