in a way an rrd is a 3 dimensional database: For any given value you specify: 1. Ds (data store), for example InOctet or OutOctet 2. Time / date 3. Resolution for example hourly data, daily data (typically rrd figures this out for you).
Highly recommend reading the docs including the tutorial. IMHO the best place to implement rrd is for time series data. Rrd's strength first and formost is it's ability to work with time series data. It's wonderful rpn(math) and graphing are just icing on the cake.
