The Characteristic and Challenges of AJAX Web Development
Ajax is a web designing technique that is used as client side to develop Asynchronous web applications. AJAX is used to communicate with server without interfere the design of the pages. AJAX is not a single technology rather than it is a set of multiple technologies.
- AJAX use the following technologies:
- HTML and CSS for display and presentation
- The Document Object model for Data interaction and data model
- XML and XSL for interchange and display of data
- XML http request to create asynchronous pages
The Characteristics of AJAX applications
The Web Page as an Application
AJAX web based applications are more intelligent than simple HTML pages. They totally act as desktop applications. They interact with back end server without even showing it. They are more responsive than simple HTML pages. AJAX web pages provide full fast user response and also refresh the page within seconds.
Data is stored on server, not on Pages
In simple web pages, server executes the whole HTML pages. When user sends a dynamic data to the server the server coverts the whole HTML page into the format which is readable by client. But In AJAX server does not have to convert all the pages, it directly receives and sends the data to the client side. In AJAX development, server has to deal with the data not with the pages. It delivers better performance and scalability.
Provides Continuous and Dynamic user Experience
It provides a dynamic user experience means that user can interact with the page and the data is being in processed by the server at the same rime but there is no wait or refresh. In classic web applications, when the user sends the request to the server, it has to wait to receive any response from the server and user cannot perform another task during this. And it happens every time. While in AJAX web design, u will get synchronous communication with the server and u don’t have to wait for the sever response. You can do multiple task one time in an AJAX based application. It provides possible nonlinear workflows.
The Challenges in AJAX development and Maintenance
There are significant benefits of AJAX development and maintenance, but it also has some challenges:
1) AJAX scripting based Approach
2) Poor user Interface
3) Mark up and language mix-up
In typical web designs, the interface of the application is coded separately than its logic which makes the application easy to develop and manage. But AJAX development breaks all “mark-up + logic “design and mixes up the logic and design which makes it difficult for programmers to develop the complex application.
