AJAX

AJAX or Asynchronous JavaScript and XML is a technique which is used to create interactive web applications.

The emphasis of this web development technique (Ajax) is on enhancing the responsiveness of the web pages which is achieved by exchange of data with the server that takes place in the background. Therefore, every time a user requests a change, the web page does not have to be reloaded. This in turn increases the utilization, functionality, speed as well as the functionality of the web page.

How can Ajax be used?

The entire data, design and content is fused together in a seamless fashion. So, when a user clicks on an application that is Ajax-driven, very less lag time is experienced. An example of this is Google Maps. The map updates itself almost instantly with minimal lag time. Ajax functions within the web browser. The Ajax engine is able to handle all customer requests as well as stores most of the informational data within the engine. It provides a seamless interaction with the user and application asynchronously. When we talk about as “asynchronous”, it means that the loaded JavaScript deals with tasks like data validation and manipulation. The display changes for the user and the transmission of data (to and fro) to the server happens simultaneously. This data transfer however is not determined or dependant on the user’s actions.

Advantages of Ajax

• Bandwidth Usage: The term “bandwidth” refers to the amount of data that is transmitted between the user and the server. The use of Ajax can substantially decrease the bandwidth usage. A page reload requires bandwidth each time the user requests a change. With Ajax, however the page does not have to be reloaded and bandwidth is only used for specific demands.
• Enhanced user experience: A web page generally requires many applications to work. In Ajax, the user’s interaction with the application is not delayed as the user does not have to wait for individual applications to load and refresh before interacting with the web page.
• For Programmers: Any language or format can be used by the programmers for specific areas. The best part however is that Ajax is based on open standards. A wide range of browsers and platforms support open standards. This further gives programmers the flexibility and accessibility to use what they require across browsers.

Outsourcing Ajax requirements

In today’s rapidly advancing web development industry, Ajax development is becoming very popular. Many web applications require complex Ajax programming. Many AJAX developers are also available as freelancers who fulfill the client’s AJAX programming requirements for various web application needs. A freelance website endeavors to deliver maximum quality and value to their clients. By outsourcing their Ajax requirements to freelancers, companies can save up to 30 to 40% of the total project cost. When dealing with a reliable freelance company, clients can be assured to benefit from skilled programmers and on time delivery of projects, all this at lower costs. This subsequently aids in securing the future of the company.
