Thanks Marc, this is a good way of looking at it. If you have files know about tenants then you're really opening a pandora's box and it's much better to have all of the per-tenant settings sourced through the database.
I guess we could have a table in the tenant database that goes along with the Tenant entity's table that has information about additional data to load. However, given the general use patterns for multi-tenant stuff wouldn't you want to load the same basic data for each tenant and then let the tenant do the rest, including loading any data files they might want (probably through an upload or referring to another server)? -David On Apr 16, 2010, at 4:15 PM, Marc Morin wrote: > we've deployed a multi-tenant ofbiz system (our own multi-tenant > implementation).
