Lex Parsimoniae is Latin for "Law of Parsimony", which pulled out into its simplest form is the The Law of what can be spared, should.

This is a theory that I have been studying for the past year and through observation believe that this can be applied to all situations that require a more efficient, functional solution. This paradigm has many names, but is best know as Occam's Razor. His razor suggests that when resources are limited or when speed of function is essential, design / complexity trade-offs should be based on what does the least harm to the probability of success, however that is defined.

Form is Function

There is a school of thought that beauty in design results in good function, but I prefer to subscribe the fact that just concentration on the functionality will by its very nature, create its own aura of design. Sometimes, the focus on functional efficiency inspires a feeling that goes beyond aesthetics and ultimately give us the sense that its form is of a higher echelon.

Barrier To Entry

The brain is an amazing piece of kit. One of its most amazing functions is its ability to optimise when processing data. Each brain has been trained over many years (or maybe it inherently has the ability) to simplify individual objects into groups. Instead of seeing each individual blade of grass, the mind sees a field. Millions of pieces of data grouped into one object because it knows, to comprehend millions of pieces of grass would take and enormous amount of effect. Effect that could be focused elsewhere. So it generalises to make life easier. This sort of information overload can happen in design as well; Too much will distract from your likely objective. Remember that 7 Second Rule? If your web app or website has 7 seconds to impress then wouldn't you prefer showing off your functional muscles? How useful your app is? and not long it takes to load the really cool (bandwidth crunching) design? Remember how it easy it is to make your mind up about someone when you them for the first time. Same rules apply.

Just Do It!

What are your objectives and goals? Hopefully, when developing a web app or website, to make your (or your users) life easier! And let's remember, this 'thing' we call the Internet is broken. So don't break any further with dodgy CSS and bloated javascript. Functional Turn Around is the most impressive aspect for me these days. Spend time developing how the app works, refine it, refine it again, then again. Then when it works, design around the edges. If you like Latin phrase then try this one:

"entia non sunt multiplicanda praeter necessitatem", or "entities should not be multiplied beyond necessity"

AJAX is a cross-platform technique that can be use on different operating system and web application based on JavaScript and DOM. It is a powerful approach of web application technique using client-side scripting to exchange data with the web server. This means that with AJAX, web pages increases interactivity and faster responsiveness of user interface by having an independent communication with the server. Gone are the traditional ways of web browsing whereby a new page communicates with each user's request. This creates dynamic web application user interface that renders effective usability of every desktop applications. AJAX primary purpose is to increase the web page's interactivity, speed, functionality, and usability.

Ajax, by definition, is not technology. In fact, it is an application of several technologies. Ajax incorporates several existing web application like XHTML and CSS for standard-based presentation; the Document Object Model for dynamic display and interaction; XML and XSLT for data interchange between the server and the client; the XMLHttpRequest to exchange asynchronous data with the web server; and the use of JavaScript as the core code for running AJAX application.

To understand AJAX, first we must know how the traditional web application works. The classic web interface trigger an HTTP request back to web server. The server then process and retrieve data before returning an HTML page to the users. This process as a model for hypertext medium makes technical sense. But as web application evolves this process does not make the user interface more interactive and practical.

AJAX, on the other hand, eliminates this problem. AJAX speed up the loading of any web application with the use of intermediary between the user and the server called AJAX engine. This adding of another layer application of eliminates the start-stop-start-stop nature on the web. The browser loads an AJAX engine at the start of session.

The AJAX engine allows the user interface and the application to interchange data asynchronously-independent of the communication to the server. So the interaction between the user and the web never slows down, no point of waiting for the server to do something.

AJAX is a powerful technique that grows exceedingly as web application. That is, AJAX is now part of the guiding principle as web 2.0 flourishes and become a practical reality. With the power of AJAX, many of the business and marketing web site are integrated with AJAX application server platform now. Most of the major products of Google such as Gmail, Google Maps, and Google Suggest are employing AJAX application. Other web services like the photo-sharing application Flickr, Amazon's A9.com, and the new Yahoo! maps depends on AJAX. The application of AJAX comes from simple function to the most complex program like Google Maps.

'Fully integrated' is a term used to describes websites that are progressive enough to include virtually every form of online media in their web presence.

If you look at sites like Yahoo, Forbes and virtually any of the major television network sites you can gain some idea of what I am taking about.

These sites contain either news of blog information. They also contain original video streaming sources and audio streams including podcasts. These sites tend to subscribe to the idea that the web user wants it all and should be able to find it all when they visit the business site.

A fully integrated site will often use flash or other animated or moving text. The interesting dynamic is that the best of these sites understand navigation and ease of use remains a critical concern for guests.

Forbes, for example is highly adept at slideshow type presentations on a multitude of topics. It could be top selling cars, entertainers, vacation hot spots, etc. These slideshows are optimized for search engines and are easy to breeze through.

It seems as if a site like this has the potential to garner some of the same consumers of media that have been courted mostly by network television or traditional newsprint.

Most fully integrated sites did not start off that way. In most cases they worked through issues they could easily address and then added features as their knowledge and confidence grew in relation to the their site development skills.

That's something I have always suggested. Do the best you can at developing a site with the most comprehensive development techniques at your disposal. That doesn't mean you have to have a fully integrated site in order to conduct business, but it does mean that you do not simply wipe your brow, release a sigh and suggest to yourself that your work is finished.

The truth is there are more skills in online web development that are being released than ever before. More programs are working with each other allowing a new robust platform for online use. The role of online web development is an ever changing - ever growing function in relation to how you manage your site and in the use of the most effective marketing tools available.

Many sites will develop an internal compass that provides the date they want to upgrade the website to include new functions. In essence they treat their website like software developers treat upgrades. Some will even go so far as to indicate their website has gone from version 1.0 to version 1.1 or 1.5. The idea is to challenge their own thinking in relation to developing a website even after the website has been launched.

This has the potential of keeping visitors interested in finding out what improvements you will come up with next.

Perhaps the greatest development rule of thumb is that you should always strive to be more integrated by attempting to meet the real and perceived expectations of your site visitors. This mentality will always give you a new goal line in your race for the perfect business.
