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.

I think the biggest mistake many of us make when we set out to build a website to make money is not to think out clearly how we are going to achieve this under our given set of circumstances.

We immediately jump on whatever bad wagon promises the best opportunity and hope to be able to achieve the same results. While hope is always nice it is action that will bring results. This is why it is imperative at the outset for you to figure out what you are prepared to do and how you are going to go about doing it.

For example list your strengths and what you are comfortable doing. Then you are going to look for ways and opportunities that will compliment your strengths.

If I had done this years ago I would have been a lot more successful. What I did instead was jump on the latest greatest opportunity, then when I would get the material I would be disappointed because many of the techniques listed where not in my field of expertise.

For example it would involve me having to cold call people to make sales and this is something I hate to do. So your first objective when setting out to build a website is to build it around a subject that you have some relationship with. Basically something that interests you.

Start out broad and be prepared to be taken down different paths that may yield more positive results in other words do not be too ridged.

Research is critical the more time spent researching the better your chances of success. Visit forums relative to your topics of choice and see what people are looking for - then with this information start to structure your site.

There are many site builders out there that can help. The one I used took care of the hosting and also helped me to market the site. This was very helpful especially starting out.

To conclude figure out what you want to do then be prepared to be adaptable based upon what the market demands. Then build a site that addresses their needs and provides solutions and you will make money.

Most websites that are created these days, are making use of the latest web applications in their site, so as to make their website appear more technically sound and upgraded too. Maintaining a standard website helps in creating a better impression upon the people than otherwise.

There are several web applications available and several that are in the pipeline. If you plan to develop your own web application and wish to be known someday for its introduction, there are a few things that you need to keep in mind before actually wishing to launch them.

The first thing that you need to analyze is the scope of the web application that is planning to develop. The scope of the application should be well researched and developed considering the users of the application and its advantages to them.

A web application usually has a number of competitive web applications as well. It is essential to do an analysis of the competitor web applications as well. You need to review the competitor website and the web application development he has undertaken. Make use of the successful technology that they have used, which can be bettered by adding to it other functional techniques.

Every website that you make with web application development must have certain practical solutions ready that will make building your website an easier task than what it considers.

A good web application generally takes a long time to be constructed and to become fully functional. It is therefore not advised to rush through any of the web application while it is being constructed. Give the developers the required time they need in order create a completely functional web application.

Once the application is ready to be installed in the website, it is important to do a quality check of the website a few days before they can actually be installed in the sites. This is an essential step since; even a small mistake can make the website drop from a height to no where and crush.
