Further Perl Programming — a 3–day course

* Closed In-House Course

Synopsis

A Perl training course designed take experienced programmers into some further perl aspects, including object orientation.

This Perl course aspects often misunderstood by those who have been using perl for some time. How to write perl modules and then objects, including inheritance, is also covered. The networking modules provide the knowledge to write client/server systems and use of network services

If you are new to perl we suggest that you look at our entry level perl course first.

Suitable for

Delegates will have had experience of perl but are aware that there are parts of Perl that they do not properly understand. Perl is a large language and 'picking it up on the job' has its limitations, delegates benefit from seeing perl done in other ways.

We find that some experienced Perl programmers benefit from our entry level perl course before taking this one. This is especially true if they find concepts like lists of hashes and hashes of arrays difficult.

Like all of our perl training courses, this course is designed for cross-platform application (e.g. Microsoft Windows, IIS, Apache, MacOS, and Linux/Unix). Unix/Linux developers will benefit particularly from Perl variants of popular Unix tools and from the abundance of Perl modules for use with Unix and the Apache web server.

Prerequisites

Delivery

This is a hands-on practical workshop based around the coding of real world solutions to real world problems.

This advanced Perl training course is run primarily as an in-house/on-site course for company groups.

The Perl course can be taught in a bespoke manner taking modules from this and our entry level perl course. This is only available for private company groups 'in-house'.

Please contact us at training@gbdirect.co.uk to arrange delivery of this course for your company or to register an interest in an individual place on a public presentation of this course. N.B. Please state clearly, which one of these two options applies to you.
