ColdFusion Background

First, let me tell you a little about ColdFusion.
ColdFusion is a server side scripting language, which is executed by the ColdFusion application server. ColdFusion works by executing CFM templates, a mixture of HTML and ColdFusion instructions to return normal HTML to the requesting browser. Often this will have included retrieving data from a database and generating web pages on the fly.
The ColdFusion (CF) application server was first developed in 1995 by JJ Allaire and is currently up to version 4.5. It exists in many incarnations, CF Express, free but fairly limited in it's power, ColdFusion Professional, just about all the features that ColdFusion server offers and ColdFusion Enterprise with advanced load balancing and the ability to spread tasks over a number of servers with advanced security features

What's ColdFusion?
When a potential employer/client asks you if you've ever worked with XYZ software running on platform ABC, say "yes" quickly and with great assurance. Then run home, fire up the Net, and figure out what the hell they were talking about.

I pulled this one a couple of years ago when interviewing for a book publisher that used a program called ColdFusion on its site. At first I wondered why the company needed a webmaster fluent in nuclear physics, but a quick HotBot search revealed that ColdFusion is a database-to-Web gateway that's turning into a very popular tool for businesses that need to get lots and lots of data on the Web lickety-split.

Variables In Cold Fusion

In this article I'm going to cover one of the most fundamental things that is in every programming language. Variables, now don't get scared, in ColdFusion they're dead easy to use. Unlike Dynamic SQL statements in ASP, they won't make your brain hurt. For those of you who don't know what Variables are, they're exactly what they say they are. You use them to make your applications do things based on what gets sent into the application. In ColdFusion all variables are in cased in # (Hash signs or pound signs depending on where you're from) hence #variablename# will be replaced by whatever value is tied to that variable.

Using pound signs and quotation marks in CFML

Pound signs (#) and quotation marks (") have special meaning in the ColdFusion Mark Up Language (CFML). Pound signs identify variables and functions in Macromedia ColdFusion expressions. Quotation marks identify data strings and text-based values for variables. This article uses examples for explaining how to use pound signs and quotation marks in CFML.

Building Your First Database Application with ColdFusion MX 7

In this six-part series, you'll learn how to build a database application with ColdFusion and Dreamweaver. To watch the tutorials before following along with the steps, download Macromedia Flash Player (in the Requirements section below). Otherwise, download and install all the software in the Requirements section so that you can watch and follow the steps within the tutorials. These demonstrations have been updated for ColdFusion MX 7.
