Chapter 14 examines how persistence techniques can be integrated with an object-oriented system. Appendix A provides a condensed summary of Perl's object-oriented features, with examples of the syntax for each. A glossary of important object-oriented terms is also provided. Throughout the text, each feature and technique is introduced with an example of a common type of programming problem that the feature or technique helps to solve. If you're looking for a specific technique to solve a particular problem, here's a list of the example problems and the chapter and section in which they're discussed.
Every textbook is a collaboration of a large number of dedicated and talented people.
In writing this book, I have been guided, helped, and supported by a multitude of generous and wise people.
