Detailed Description

This class is part of the CRUND benchmark that measures standard database operations over a series of transactions on an increasing data set.

The abstract database operations are variations of: Create, Read, Update, Navigate, and Delete – hence, the benchmark's name: CRUND.

The actual operations are defined by subclasses to allow measuring the operation performance across different datastore implementations.

Urban Dictionary: crund

used to debase people who torture others with their illogical attempts to make people laugh;
reference to cracking obsolete jokes;
a dance form;
to hit hard or smash.
