Web App Disadvantages

Creating web applications is as complex as writing a thesis paper or a dissertation. It does not only necessitate quite a tedious amount of effort to perfect the function of the program but also demands one stable thing from the user: internet association.

Whenever a program is being written, it takes several factors in deliberation but the most important of them is the user-interface. It is imperative that the application’s interface is easy to understand, lest it will not be used as it was intended to be so.

Using a atypical office text created raises an issue on standards compliance, moving the evasive issue of file partaking and association. What must be noticed is that these browser applications are used by accessing the internet through the remote servers. It is threatening however, for the document, if the connection is suddenly lost or interrupted. Chances are, the document being programmed online will be lost and inferior, irretrievable.

This kind of disadvantage poses a threat to the survival of the web applications, hence, companies such as Google have made preliminary solutions to this problem. However, for now, only prototypes have been developed to repress the threat raised by this problem. Just like so, Google has created Google Gears—a beta display place that aims to improve the usability of web applications.

AJAX-powered Web apps disappoint power users

Most power users are very much disappointed with the performance of Rich Internet Applications (RIAs).  It is based on the Asynchronous JavaScript with XML, or AJAX, according to a new research team report from Forrester Research Inc.

As a result of the AJAX limitations, the research firm recommended that business users would consider an emerging next-generation RIA technologies like Adobe AIR from Adobe Systems Inc. and Microsoft Corp.’s Silver light tool set. And according to the report, which was released last week, the power users find that AJAX applications are very much complex and their reaction time is limited.

Database-enabled Ajax with PHP

Ajax has taken the Web to a new level by offering an intuitive interactive model that rivals the desktop. To compete with desktop applications, database interaction is necessary to unleash the true power of an Ajax Web application.

In this article you’ll learn how to create database-enabled Ajax requests using PHP and MySQL. We begin by creating the front-end HTML and JavaScript files used to make requests to the server-side. The requested
server-side is a PHP file which bridges the gap between Ajax and a PHP object that connects to a MySQL database and returns results as an XML response to the Ajax engine. To cover this functionality you’ll learn about the concepts from a high level overview rather than focusing on each and every line of code. The complete source code for this sample can be downloaded and is necessary to create a working sample on your personal server. Let’s get started by taking a look at the front-end.
