CIW Perl Fundamentals Part 2: Manipulating Scripts

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. As a prerequisite students must have the CIW Foundations series certification (exam 1D0-410) or equivalent experience for those students not seeking Master CIW Enterprise Developer certification. This course will help students prepare for exam number 1D0-437. In addition students should have taken the first part of this series (87041).
