AUDIENCE:   System administrators, database administrators and testers. The course is also suitable for developers working with CGI programs or other applications. PREREQUISITES:   Students should have attended our Perl Programming - Part 1 course or have equivalent knowledge. DURATION:   2 days. Hands on. OBJECTIVES:   Perl is a mature, extremely flexible, general-purpose language, which is especially well suited to textual manipulation. In addition to its brilliant built-in facilities, there are vast freely-accessible libraries of Perl code to help build almost every conceivable application. It is, for instance, in many cases the language of choice for implementing web server-based CGI programs. And it’s available free-of-charge. This course builds on the techniques in Perl Programming - Part 1. It covers the more advanced programming and data structuring techniques provided by Perl, suitable for high-level applications of all types, including references, modules and object-oriented techniques. There is also an optional third day that covers techniques which may be applicable for specific types of applications, as well as some legacy techniques. Where applicable, for one company, one or more of these topics may be substituted for topics in the two-day framework.
