(October 7, 2005) - AJAX isn't a technology, or a language, and there's no recipe to implement it; it's just a combination of various components to achieve something you otherwise couldn't: asynchronous http requests. However, since early 2005, when Google and Flickr popularized the concept, its use has grown rapidly. The name AJAX is short for Asynchronous JavaScript and XML. It uses the JavaScript XMLHttpRequest function to create a tunnel from the client's browser to the server and transmit information back and forth without having to refresh the page. The data travels in XML format because it transmits complex data types over clear text. AJAX uses XHTML for the data presentation of the view layer, DOM, short for Document Object Model, which dynamically manipulates the presentation, XML for data exchange, and XMLHttpRequest as the exchange engine that ties every...

Building a Drag-and-Drop Shopping Cart with AJAX

Keeping up with the latest Web technologies is tough nowadays. Every week it seems new sites are launched that push the envelope further and further in terms of what can be accomplished using just a Web browser. The rise of AJAX over the past several months has taken over the development world and breathed new life into the Web. Although these techniques have been possible for many years now, the maturity of Web standards like XHTML and CSS now make it a viable alternative that will be viewable by all but the oldest browsers. It's also been possible to accomplish many of the same things using Flex or Flash, but the development cycle with those applications is typically more involved and the overhead often not justified. We're going to harness the power of the Scipt.aculo.us JavaScript library to provide our interaction. As their Web site states, this library "provide... (more)

Rich Internet Applications - State of the Union

[This prescient article first appeared on SYS-CON.com nearly 12 months ago.] We are entering an era of Rich Internet Applications (RIA),  and many enterprise development managers are facing the dilemma - which way to go - remain with  tried and true Java or .Net technologies or less known yet AJAX, Flex, OpenLaszlo or a number of other vendors.  This article is an attempt to give a brief overview of what's out there on the RIA market. Historically there have been major shifts in the software industry. We moved from mainframes with dumb terminals to client/server. Users gained in convenience and productivity, and mainframe systems were patronizingly labeled as legacy. With the availability of the World Wide Web industry visionaries turned the tables: vendors and corporate IT had been eager to get rid of the complexity of client/server version management and technologist...

What Really Leads to Successful Software?

ColdFusion MX is a complete, from-the-ground-up rewrite of an existing piece of software, shifting its architectural base from a purely interpreted language sitting atop C, its base language, to one that compiles into Java code. That's quite a shift. For months Macromedia has been reassuring developers that, whatever may happen beneath the covers, nothing changes about our code. In one sense that's absolutely true. Take code written under a previous version of ColdFusion and - almost without fail - it will run perfectly with ColdFusion MX. In that sense "nothing changes" is an accurate reflection of reality. On another level "everything changes" is an equally valid description of the new world that CFMX has led us into. ColdFusion's new foundation of Java offers us new capabilities, such as using JSP custom tags in ColdFusion pages. Charlie Arehart (www.systemanage.... (more)

The Relational Database: Center of Most Advanced Applications

You won't get very far while building ColdFusion applications without the need for a relational database. Since ColdFusion is so easy to use, many developers come from non-programming based backgrounds, and proper database design remains a mystery. Perhaps you've worked on other applications, such as a spreadsheet application in Microsoft Excel or used an Access database with a single table to store data. Both of these options serve their purpose, however they are not the best choice for web applications. In this architecture focus issue, I wanted to take some time to introduce you to relational database concepts. Understanding the Terms Before I start blabbing about database this and database that, I want to make sure you understand what I'm saying. So let's start by defining some common terms that you should be familiar with. Database: A database is any collection... (more)

Building a Forum with Macromedia Dreamweaver From Adobe Part 2

In Part 1 of this tutorial, we taught you how to pull information from a database in order to set up a forum front end and how to style it with CSS. In this article, you will see how easy it is to build a user authentication system for your forum. Setting Up User Authentication In the following sections of this tutorial, you will use ImpAKT to build a user authentication system for your forum. You need authentication to prevent pranksters from posting a load of garbage to your forum and getting away with it. If users want to post messages to the forum, they must register an account, activate it, and then log in. Only then will they be able to post messages to the forum. To build the user authentication system, you will do the following: Configure user login settings from the InterAKT Control Panel. Create a user registration page. Create the user login page. Create a... (more)

Your First Adobe Flex Application with a ColdFusion Backend

Flex is a complete set of tools to develop rich Internet cross-platform applications based on the Flash platform. With Flex, you can create applications that not only have the "wow factor" necessary to please clients and users alike, but the "usability factor" necessary to make your application a real success.  Flex 2 has recently been released and can be downloaded at Adobe's Web site. This release includes Flex Builder 2 (an IDE based on Eclipse) and Flash Player 9. At Adobe's Web site, you'll also find tools specifically for ColdFusion such as the ColdFusion/Flex Connectivity package and ColdFusion extensions for Flex Builder. If you know how Flex 1.5 works, you'll be happy to hear that Flex 2 doesn't require a Flex server and that you can develop and deploy applications with Flex 2 for free using the Flex SDK (if you don't use the IDE). A Flex application comm... (more)

Vene, Vidi, Adobe!

Adobe staged its MAX 2006 developer and customer conference under the theme "Beyond Boundaries" to showcase the company's emerging technologies and provide a glimpse of future innovations. Adrian Bridgwater attended to drink it all in. Adobe's MAX 2006 event was held at The Venetian Hotel and Casino in Las Vegas from the 23rd to the 26th of October - the company's first event of this kind since joining forces with Macromedia. Adobe's focus was directed at highlighting the newest breed of rich applications and what it likes to call "engaging content and experiences" under the banner of its next-generation technology. Described by Adobe as a chance for its community of developers and customers to reinvent the future of the Internet and design in virtually every medium, MAX 2006 was billed as both a milestone in the integration of Adobe and Macromedia and a reflectio...
