 \section{Data storage model}
 Many amateur radio operators choose to store all the contacts they ever make in a single \textit{logbook}, whereas others keep a separate logbook for each year, for example. Each logbook may be divided up to form multiple distinct \textit{logs}, perhaps one for casual repeater contacts and another for DX'ing. Finally, each log can contain multiple \textit{records}. PyQSO is based around this three-tier model for data storage, going from logbooks at the top to individual records at the bottom.
