Perl & CGI For Non-Programmers

Public scheduled course £990
Prices exclude VAT. |

The Perl programming language is used to generate CGI scripts that add sophisticated interactivity to online content. Perl allows you to process form data, generate dynamic pages on the fly and validate user information. Perl scripts are used to automatically extract the latest available data from a back-office database ensuring that online information is up to date – vital for time-sensitive data such as news, financial information, prices, stock inventory, etc.
This practical hands-on three day introductory course is designed specifically for those with no previous programming or coding experience although an understanding of the basics of HTML is required. The course will give you the programming skills to make your site more responsive to your site visitors' needs and requirements. This course can be taken as two days of individual tuition if you are already an experienced programmer - please call for details.
