/*!
 * \brief The Row class provides an interface for retreiving and submitting entries from the database.
 *
 * \details The Row class is a base class and when instantiated, the appropriate subclass should be used.
 *
 * The database holds all the data related to the logbook in different tables. Each of these tables is composed of
 * rows. Each row has different columns and each column contains the data. As such, an entry can be thought of
 * as a row in the database. The row class encapsulates the data contained in each row.
 *
 * A row is uniquely identified by its position in the database, consisting of the table name (QString) and the row id (int).
 * A new entry, which is not yet in the database has the row id 0. If a new row object is created, the hasData
 * bool is set to false. Before submitting the entry to the database, setData() has to be called to fill the row
 * with data and toggle the verification bit.
 *
 * The Row Object holds all the necessary information the Database class needs to commit (create or update) it.
 * The Identifying information can be accessed with getRowId and getTable() / getTableName().
 *
 * For convenience and readabilty, subclasses exist that have the table property pre-set. These rows are then
 * referred to as entries. See AircraftEntry, FlightEntry etc.
