following appendixes:
Appendix A summarizes basic Perl syntax, including
object-oriented features.
Appendix B presents the main Perl DBI application
programming interface (API) functions.
Appendix C describes the basics of regular
expressions (regexes), patterns of literals and meta-characters used
extensively by Perl for pattern matching.
Appendix D summarizes the Perl data-munging
modules that are helpful in formatting and transforming data for data
warehouses and other such Oracle applications; it includes sections
on numeric, date, conversion, and XML modules.
