Course Length:

5 Days

Course Description:

The course begins with a thorough treatment of packages, modules, and libraries. Next, Perl references are studied. This gives students the necessary background to write object-oriented Perl. Various applications areas that use object orientation are studied next. These modules include the Tk.pm module for building Graphical User Interfaces, the DBI.pm module which provides a portable way of querying databases, the CGI.pm module for writing CGI programs, and the Socket.pm module used in client server networking applications. Finally a treatment of XML and Perl is undertaken.

Who Should Attend:

Programmers, end users, system administrators, network administrators, CGI script writers should attend this course.

Benefits of Attendance:

Upon completion of this course, students will be able to:

• Download, install, and use Modules from the Comprehensive Perl Archive Network (CPAN).
• Use the modules in the Standard Perl Distribution.
• Write POD (Plain Old Documentation) sections of Perl modules.
• Use Perl references to solve many programming problems including those problems involving arbitrarily complex data structures.
• Distinguish among packages, modules, libraries, and classes and use each one effectively.
• Write client/server applications using the Socket.pm module.
• Write Graphical User Interfaces (GUIs) by using the Tk.pm module.
• Write Perl CGI (Common Gateway Interface) scripts.
• Write Perl applications that make queries to real databases through the use of the DBI.pm module.
• Write Perl applications that produce and process XML documents.

Prerequisites:

Participants should be well-versed in the fundamentals of Perl.
