\brief Shows how to use Qt SQL classes with a model/view framework.
The Books example shows how Qt's SQL classes can be used with the model/view
framework to create rich user interfaces for information stored in a database.
\borderedimage books-demo.png
Information about a collection of books is held in a database. The books are
catalogued by author, title, genre, and year of publication. Although each of
these fields can be displayed and edited using standard widgets, an additional
field describing an arbitrary rating for the book needs something extra.
Books are rated using a system where each is allocated a number of stars; the
more a book has, the better it is supposed to be. By clicking on a cell
containing the rating, the number of stars can be modified, and the rating in
the database is updated.
