CIW Perl Fundamentals Part 1: Basic Syntax

Audience

The audience for this course includes application developers software engineers and other network designers. Candidates for this exam create interactive Web pages using client- and server-side Web applications; access relational database systems from Web applications; implement applications using component technology; and create parameters for environment variables.
