| 51 | Information about a collection of books is held in a database. The books are
|
|---|
| 52 | catalogued by author, title, genre, and year of publication. Although each of
|
|---|
| 53 | these fields can be displayed and edited using standard widgets, an additional
|
|---|
| 54 | field describing an arbitrary rating for the book needs something extra.
|
|---|
| 55 |
|
|---|
| 56 | Books are rated using a system where each is allocated a number of stars; the
|
|---|
| 57 | more a book has, the better it is supposed to be. By clicking on a cell
|
|---|
| 58 | containing the rating, the number of stars can be modified, and the rating in
|
|---|
| 59 | the database is updated.
