How multi-tenant database can be arranged in NoSQL in general and in RavenDB in particular. For SaaS applications, multi-tenancy might seem like a simple problem at first glance.

The default autogenerated semantic IDs (e.g. users/1-A) are good enough – robust, concise, human-readable, customisable. Of course, there are other options including GUID if you want to go fancy, but the YABT ("Yet Another Bug Tracker") sticks to the defaults and here are some hitches you may...
