RRD is the Acronym for Round Robin Database. RRD is a system to store and display time-series data (i.e. network bandwidth, machine-room temperature, server load average). It stores the data in a very compact way that will not expand over time, and it presents useful graphs by processing the data to enforce a certain data density. It can be used either via simple wrapper scripts (from shell or Perl) or via frontends that poll network devices and put a friendly user interface on it.

It is incredibly easy to accidentally drop or add a carbon atom when drawing complex ring structures or long-chain intermediates. Count the carbons in your starting material, count them in your intermediate, and count them in your final product.
