Perl 5 Day

This Perl course is designed for those people who have had little or no experience of Perl and would like to cover Perl from the beginning upto and including some advanced topics. We will take you through the basics of writing Perl correctly and understanding it, to working with references and creating Object Oriented code, enhancing your understanding of many Perl modules already in existance.

ON COMPLETION

  • Have a greater knowledge of the Perl language
  • Feature rich commands added to your vocabulary
  • Create modular and maintainable code
  • Create modules, and work comfortably within a project team
  • Work with complex data structures and references
  • Handle errors and exceptions
  • Program network application with FTP, HTTP and Email
  • Connect to Win32::ODBC and DBI databases
  • Understand Object Oriented Perl and write it

WHO SHOULD ATTEND?

This course is intended for those of you who wish to be introduced to Perl, but at the same time wish to rapidly enhance your understanding to an advanced level. An understanding of a previous programming language or scripting language (e.g. Unix shell scripts or VBScript) would be an advantage. If you have fumbled your way through Perl scripts without knowing what they do, this course will suit you.

COURSE WORK

The course work is based around a 40/60 approach to lecture and hands on giving the attendee the chance to really work with the system and see its potential. Where possible the practicals will use real world examples and useful starting code that can be integrated into new or existing projects.

PRE-REQUISITS

A previous programming or scripting language. No knowledge of Perl is required.

DURATION: 5 DAYS
