Name one of the foremost 'inconvenient truth's' in coming up with an efficient data model for a relational database?
One of the most inconvenient truths in building an efficient data model lies in coming up with tables that will need to be kept denormalized.

A database is sluggish when information obtained most often, and by most people, causes a choke hold on the system.
