-\section{Three-tier 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, going from logbooks at the top to individual records at the bottom. From an implementation point-of-view, a database is analogous to a logbook, a table in the database is analogous to a log in the logbook, and the records in each table are analogous to the records in each log.

+Rather than storing each log in a separate file, a single database can hold several logs together; in PyQSO, a database is therefore analogous to a logbook. Within a database the user can create multiple tables which are analogous to the logs. Within each table users can create/modify/delete the records which are analogous to the records in each log.
