[Zope-dev] ZPatterns & scalability...

2000-12-05 Thread John Eikenberry
Just to get more opinions... we have a service coming up where we'd like to use a Zope/Zpatters solution. Its a feedback tool, with the potential of up to 50,000 entries. These would be stored in a Specialist/Rack/DataSkin combo, stored in a standard zodb/filestorage system. Using a ZCatalog for

Hi, I have an application that stores state data in a SQLServer database. The Zope and database servers run on different windows machines, using the ZODBCDA product to connect Zope to the ODBC machinery. What I have been observing is that the Zope client's memory usage increases consistently wh

I've been using DOmain Modeling Environment(DOME) for OOA/OOD recently. I use it because like ZOPE it has many features most important one being free. It has support for Coad notation and a list of others. IMHO it could be the default ZPatterns design tool of choice because you can extend it t

Thanks for the tip. Yes, the HistoricalRevisions subsystem looks interesting. Im not sure it solves my problem though, in that the revisions seem to be for a single given object, rather than for a given subtree or site. They certainly dont seem to apply to folderish objects. For my application,
