The W3C standards summary for Rich Internet Applications is the solution to the accessibility and usability problems of the Web 2.0. Web 2.0 has the issues of usability and accessibility due to the limitations of the XHTML. However, the Rich Internet Application offers novel ways of filling up the gaps in the XHTML through effective communication. The best part about using RIA is that it can enhance the accessibility of your websites immensely and that too instantly. One cannot claim a to be rich simply because it is developed by using Ajax, Flex or Silverlight there are certain primary principles that it must embody. Here are the six principles that exemplify rich applications:

• Principle No.1- Make It Direct-  This principle means in simple words means that "Where there is output, let there be input." as stated by Alan Cooper. It is important that the application allows direct manipulation. For instance, if any editing is required to be done in the content then instead of making a separate page it should allow the editing in the same page itself.

• Principle No.2- Keep it Lightweight-  Making use of contextual tools will enable you to create lightweight applications. What we mean by lightweight over here is that the applications should not cause much physical or mental effort to the user who is interacting through the application.

• Principle No.3- Stay on Same Page- Ajax has made it possible for the developer to develop a product that does not need to refresh the page every time. Refreshing a page with every click disrupts the mental flow of the user and hence, it is better to develop an application that keeps the user on one page itself for several sorts of communications.

• Principle No.4- Render an Invitation- Getting discovered is the most important thing on the web as there is plenty of content on the web. The easy to get your application discovered is by providing an invitation. The invitation will not make the user aware but will also take the communication to the next level. Invitations can be beneficial even when new features are introduced.

• Principle No.5- Use Visual Transitions- Flash has enabled the developer to use several visual transitions while developing the rich internet applications. The use of animations, cinematic effects, images and so on can be a very powerful tool for communication. This will enable you to enhance the overall look and feel of your website.

• Principle No. 6- React Immediately- The interface that is responsive is the best one to have for giving the users a complete satisfaction. A responsive product becomes very helpful in increasing the usability of the product.

Thus, these six principles together help you in developing a rich internet application that has amazing usability and accessibility.

Gone are the days when one had to become almost a system administrator and have the software installed in the desktops. There are no doubts about Web being a highly dynamic field and hence, development of web applications is just being true to its nature. Web application is basically an app (application) that can be accessed through the web browser itself and therefore there is no need to download it to the desktop. Wikipedia defines it as “The term may also mean a computer software application that is hosted in a browser-controlled environment or coded in a browser-supported language and reliant on a common web browser to render the application executable.

Advantages of Web Apps:

• It is compatible with cross-platform. The web bases software applications are designed in a very easy way so that they can work well on any computer system. The web app designs work with Linux, Mac, Windows, and other operating system. All it need is an internet browser.

• Web apps development has made the most path breaking entrance in the WWW as it has eliminated the need to download. These apps are potent to execute all the required details from the browser itself and hence save the time and the space wasted in downloading software.

• Every time and everywhere access is possible with the web applications. The web apps can be made use of from any internet browser and hence there is no restrain of place and time.

• Web applications are piracy proof and they have no legal rights problems with it such as administration rights and so on. This is the best part since there is no need to obtain the license or administration rights for using it as it was with the traditional software.

• Web application development has made it easy for people to put up any update on it. The updates once applied to a central location allow all the users of the app to benefit from it and that too instantly. Thus, no need to install any updates.

• No need for a lot of anti-virus software too as there is no need to download so no risk of getting virus. Though it is required for accessing the data that is not yet available in the web applications form.

• The desktop applications are difficult to be adapted on the mobile phones but the web apps are potent enough to do this easily as plenty of mobile phones now have internet access.

The world of internet is ever evolving and introducing new and better ways to give the end user a much more rich experience over the internet. Rich Internet Applications is the path breaking innovation in the world of World Wide Web as it renders it with lot of functionality. RIP enables the user to have a responsive interface and hence, providing the required information quickly and in a much more efficient manner. Most of the websites today make use of rich internet technology so that they can give their customers complete satisfaction.

Rich Internet Applications (RIA) is basically pieces of software that can be accessed through web browser. The primary advantage of this to the user is that there is no need to download any software for using it as it can be used directly from the browser. Several RIA technologies are available free of cost such as Adobe Flash, Adobe flex, Microsoft Silverlight, Ajax and JavaFX.

However, at times the user needs to install certain plug-ins if the browser is not the latest one. Usually, the RIA integrates along with the technology already built into the web browser. Now-a-days all kinds of rich applications are found for instance, word processors, spreadsheets, online games and so on. Not only this, it is due to these rich applications that one can even access their bank accounts sitting at home itself. Hence, these applications are specially meant for offering the user with high interactivity and functionality.

The three main benefits of the Rich Internet Applications are accessibility, performance, and consistency. RIA is completely about offering the user of the web an optimum experience over the internet and more than that it enables the companies to have a competitive edge in the market. The implementation of technologies such as Ajax, Silverlight can hence enhance the value of service oriented systems.
 

LAMP is a technology that became a lot popular in the early 1990’s as the technology allows the user of the web browser to execute program on the web server. The full form of LAMP is Linux, Apache, MySQL, and PHP/Perl. Linux is an operating system while Apache is a web server, MySQL is a database management system, and the PHP or Perl or Python are the scripting languages.

The combination of all these allows a user to run a program on the web browser with ease. The designers of all these open source programs did not really make all these keeping this combination in mind, but the combination has become popular by itself as it is cost effective and also because it is ubiquitous.

Any website designer who wishes to have a high quality of PHP and MySQL or pgSQL web applications with convenience and at low cost then LAMP provides the best platform for it. Several of the custom designed e-business solutions are made on this ultimate combination of LAMP. This has made it the most famous and widely used open source combination. PHP can develop dynamic websites that is data base driven; therefore, it can be used for making e-commerce websites or any other websites through this unique combination.

LAMP is thus a very reliable and widely used web application and development platform that is freely available. It is a platform that enables the user to develop and deploy simple as well as complex database driven websites on the server. Several noteworthy advantages of LAMP are that it is low costing, reliable, scalable and secure web applications. The best part about this technology is that it can be used for websites of all kinds whether large or small.

There are many companies that provide with advanced web applications these days and therefore a range of web applications are variedly found. The web applications development services enable the user to use it in an easier way but at the same time, web applications takes a longer time to develop. However, for making advanced web applications it is necessary to have appropriate planning. Here are some of the reasons for the importance of planning while making web applications:

Firstly, the planning of it will clear your requirements and therefore, you will get only the features that you require. A laid out plan will clarify your need regarding the functionality or the features that you should have in various areas of application.

Secondly, a plan becomes a blueprint or a road map and hence will always keep you on right track. Chances are they you might be able to complete creation of the application quickly as the plan is already plotted and you know which way to move for achieving the desired goal.

Thirdly, planning will also allow you to finish the task in the appointed time. Generally the web developers find it difficult to finish the custom application design in the stipulated time. But if it is planned then it is achievable. Also the proper planning will allow you and the client to discuss about the time limit extension, if required.

Fourthly, since the advanced web application is planned, it will also help you to reduce your expenses. Since you are moving in the right direction and can finish the work on time, it will not add up to any unnecessary extra expenses.

Fifth reason is that you will get the end result that you were seeking. There would only be a considerable variation in the expected web application and the created web application as every move is first planned and discussed with the client.

Sixth reason is if you are a client, then the planning from the appointed company will give you a fair idea of its performance and capabilities. If you don’t like the plan of the web application then you can withdraw the project.

However, besides these reasons it is also necessary to keep the plan simple and easy to understand while you make advanced web application plan. For this you can break down your ideas and deal with each one separately. The plan for it generally includes description, goals, budget, target audience, front end feature list, admin feature list, user feature list, site map, and summary.
