Detailed Description

This class benchmarks 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.
