Course Description
Overview
This four-day course offers many benefits for organizations that do a significant amount of Perl programming. Several chapters teach advanced productivity features of the Perl language itself, including debugging techniques, sophisticated list usage, code references, tied variables, and effective package use. The course puts programmers on very solid ground for doing object-oriented programming in Perl. Programmer productivity increases tremendously by reusing modules written by others, so this course teaches how to find, install, and use libraries of routines from the thousands of freely available Perl modules on the Web. Students learn how to use SQL to access relational databases (such as Oracle) with the DBI/DBD Perl modules - most production Perl programs need to do this, especially web-based back-end server programs. Students will also learn how to build graphical interfaces in Perl using the Perl/Tk module. The course teaches several other productivity features as well, including extending Perl with C/C++, embedding the Perl interpreter in another language, documentation with POD directives, module development and distribution, and advanced Perl design and implementation considerations.Objectives
