Perl Programming with Web Development — a 5-day course
Synopsis
A Perl training course designed cover all the basics of Perl Programming and also enable web developers to build
dynamic (database-driven) e-commerce web sites using the Perl programming
language, its specialist web modules and CGI (the common gateway
interface).
This Perl course includes a thorough grounding in generic Perl programming
before covering specialised Perl web development tools and techniques (the
stuff that some people think of as CGI Perl) on the final day.
If you are new to programming or web development and are contemplating the use of Perl we suggest that you read our
notes on introductory courses first.
Suitable for
- Programmers who need to develop serious web sites on any of today's major
platforms and in multi-platform environments.
- Web Developers with limited scripting experience (such as JavaScript,
VBScript, Unix/Linux shell scripting, etc., rather than pure programming)
will benefit from this course, but may find it demanding. Some may choose to
extend the same material over more than five days, with additional hands-on
practical exercises.
Delegates with backgrounds in C-like languages will recognise elements of
Perl syntax and can use existing knowledge to progress quickly, but they must
beware the temptation to translate literally from C/C++. Perl's native way of
doing things is invariably more flexible and better adapted to specialist web
development tasks.
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
- This Perl course assumes that delegates can already program in at least one
programming language or scripting language, e.g., C, C++, Java, PHP,
Visual Basic, Pascal, or COBOL.
Delivery
This is a hands-on practical workshop based around the coding of real world
solutions to real world web developers' problems.
This course can be run both as in-house training for company groups
and is also a scheduled public course for individuals.
The general Perl programming issues are taught as our four-day Perl Programming
course with an extra day devoted exclusively to web development tools and
techniques. See
, our general perl programming course outline
for detailed descriptions of it’s course content. This shorter version 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. Please state
clearly which of these options applies to you.
