Web Development: Giving New Heights to Internet

The development field has seen the inception and widespread usage of various technologies like AJAX, LAMP, XML, CSS, and DHTML etc.

It was HTML and only HTMl that was burdened with satiating the technical demands of creating websites in the early days of internet. But over the time with the larger dependency of the market on Internet driven services have led to a whole new field in guise of web development.

It is not about static websites; you can find everything on Internet that includes dynamic websites, community portals, e-commerce sites, content management system, Online shopping carts, social communities, blog sites and many more. You can avail any and every service through the relevant sites on Internet. So, whether it is ordering a pizza or transferring money or booking tickets, you perform daily chores just with the click of mouse. And this is all because of the consistent efforts undertaken by the web development.

You can track the progression of the field of web development starting from HTML which incorporated CSS (Cascading Style Sheet). This has been followed by the refined and robust technologies like AJAX, LAMP, DHTML, XML, JOOMLA, DRUPAL etc.
AJAX (Asynchronous JavaScript with XML) has enabled the transfer of data and its management in a flawless fashion and simultaneously creating and operating on web pages. LAMP is an amalgam of Linux, Apache and My Sql which makes your web site dynamic in nature and also provides the site with the functionality of managing and creating database.

XML (the upgraded version of extensive markup language) is akin to CSS in ways that it separates contents from the layouts. However, it can be implemented in any environment and applications. DHTML is JavaScript adhered with HTML/XHTML is another package that helps websites that are similar in development to AJAX but this is more complicated in design. It is widely used in the design of sites which necessitate user interfaces.

Affordable Web development aims to ease the way we carry our routine business and this is why the field in itself is quite dynamic in nature. Every passing day you can see the subtle differences in the way world goes about business.

Ajax - What Is It and How It Works

Ajax stands for Asyncronous Java Script and XML and is known for making web applications function as fast (or faster) than desktop applications. Let’s talk about what a typical web application looks like. For instance, a Google search:

* you enter some text in the search box.
* you then click the search button.
* the page is refreshed and you get results backs.
* this entire process could take a few seconds to minutes depending on how much data you’ve requested, the load on the webserver, your internet connection and so on.
* in short, it is a pretty quick process, but it can be quicker…

So how can AJAX improve something like a Google search. Using the previous example above:

* you enter the same text into the search box, however now your results are returned instantly as you’re typing!

That’s the power of AJAX, instant data is returned without having to click submit and waiting for the screen to refresh. So, that’s the end result of an AJAX enabled website, instant data is returned based on the letters you are typing (as in our AJAX Google search example).

Technically speaking, this is how AJAX is working in the background:

1. A webpage executes some Java Script that can grab data from a web server as it’s needed.
2. If more data is needed Java Script invokes an object called XMLHttpRequest. This object transparently and instantly retrieves data then presents it without having to refresh the browser.
3. The data that’s returned is usually XML. This XML can easily be formatted using HTML and CSS.

Keep in mind that those 3 steps above happen instantly! If you want a real world example of AJAX in action just start to do a Google search. Those results that drop down as you’re typing are the results of Ajax!

A Brief about Ajax Application Development

Asynchronous JavaScript and XML, commonly known as Ajax is a web development tool that is used to create interactive web applications. It is mainly an amalgamation of several technologies, each having specialties of its own and becoming more powerful when integrated together. Ajax includes XTML and CSS for standard based presentation, Document Object Model for dynamic display and interaction, XML and XSLT for data interchange and manipulation, XML Http Request for asynchronous data retrieval and JavaScript for holding everything together. While exchanging data with the web server, it uses client side scripting which enables independent communication with the server. Ajax application development is gaining popularity day by day as it is supported by most of the browsers.

In the classic web application model, a user has to wait every time an Http request is sent to the server for processing an HTML web page to the client. In the Ajax application model, an Ajax engine is introduced between the user and the server which eliminates the need of waiting for the server’s response. The engine is loaded every time by the browser whenever a session is initiated. It allows asynchronous communication between the user and the application. As a result the speed, interactivity and usability of the web pages are greatly increased. Using Ajax, the user fetches small chunks of data from the server behind the scene and not the complete set of information. Simple processes such as data validation, data editing memory are handled by the Ajax engine. If it needs help from the server, those requests are made asynchronously, using XML. From simple to complex, Ajax applications can be of any size. It is an important development that has been made in the world of web applications and its importance is growing every day.

There are many Ajax web development companies, lending their valuable services in integrating Ajax. It has been used by many big companies in the world of the web. Many products of Google like Gmail, Orkut and sophisticated Google maps are based on Ajax technology. Likewise, the Yahoo maps are also dependent on this technology.

Ajax Development Services- Know the Basics

The technology is advancing at a lightening fast pace and making way to more innovations which have made a difference in today’s world. One such revolution that has dramatically transformed the virtual web world is Asynchronous JavaScript and XML or AJAX. If you have heard a lot about this word and are curious to explore as to what sort of profit it will incur to your website, this is the right article for you to acquaint yourself with this technology. This application has made Google Maps, an instant hit with the users, thanks to its quick page loading which allowed the users to scroll down the maps very conveniently without waiting the page to get loaded. This has resulted in the increase of the AJAX development service waiting to cater to the needs of the website owners.

Ajax will give you a respite by allowing your webpage to load in fraction of a second, a very less time for those whose heavy websites take ages to upload. And this has been a phenomenal hit amongst the users. However, you must realise the Ajax services only gives parity to the users. There are websites like eBay and Amazon, which are minting money without the usage of Ajax application development and still going strong with each passing day. The benefit of this application is that it gives the users an extra level of advancement that makes it easier for all users to use and thus admire it. Big players like Yahoo Maps and MapQuests have also shifted to Ajax thus giving way to better navigated websites.

At the face value, Ajax may look a very user friendly application. However, you must be careful in implementing this into your website. The Ajax development companies may go gaga about the benefits of this application, but it has its own disadvantages. The application might make your website more confusing, forcing the visitors leave the website without exploring it. The Ajax would not use the back button feature as a user might expect. Also the bookmark feature also doesn’t work very well with this application.

So, the usage of Ajax application should be done under caution. If you are doubly sure about its pros and cons and convinced about its usage, only then you should use this application.

AJAX and SEO – can they co-exist?

Before getting into an understanding of the fuss surrounding the co-existence AJAX and SEO, let us first answer the question. Can SEO and AJAX co-exist? The answer is that the two will definitely have to co-exist, and both developers and end-users will stand to benefit from this.

Emerging technologies tend to have an uncomfortable relationship with existing techniques. The obvious reason is that the existing techniques are created on the basis of existing technologies. AJAX and SEO share a similar relationship.

Asynchronous JavaScript and XML (AJAX) brings together various technologies to create a technique that make web pages more like web applications. The key benefit of AJAX is that the page has a greater sense of interactivity, and the user requests are rendered in smaller portions. In other words, AJAX enables the creation of a scenario that is both data-centric and user-centric. Developers were skeptical towards the use of AJAX, but with the introduction of the Google Web Toolkit (GWT) this changed drastically. GWT made AJAX easier for developers to create applications in, and needless to the say the end user stands to benefit the most from this.

Search engine optimization (SEO) is a technique used to enhance the visibility of a website vis-à-vis search engines. Using various SEO techniques, websites enhance their visibility so that they would be ranked high on the Search Engine Results Pages (SERP). SEO has become a part of the development lifecycle of websites. Companies, big and small, are becoming increasingly aware about the importance that SEO has, and what it can do for their business.

There was widespread apprehension about AJAX, and its invisibility to search engines. Words like search engine unfriendly were being used to describe AJAX. What was happening with AJAX was reminiscent of the fate that Flash had faced before this. JavaScript, which is what AJAX applications use, is not visible to search engine spiders. In other words, when a search engine spider is crawling a website that is created using AJAX, most of the content would not be visible. The reason for this is that since smaller portions of content are rendered with AJAX, there are no unique URL’s that a search engine can direct searchers too. In other words, the whole purpose of enhancing interactivity would fail.

This can be better explained with this example. If you a product catalog with x number of products on it, you would obviously want that the search engine has a distinct page for every one of the products on the list. When you create this catalog using AJAX, all the information is there on the same page for the user to click and explore. But from the point of view of the search engine crawler, there is one page and therefore it does not direct any traffic to the individual products on your page. One way to circumvent this problem is to create a parallel site targeted for search engine spiders, and other browsers that do not support JavaScript. This is one available option that many websites have already successfully employed to make the two ends meet. And there are in fact, many success stories of websites that have used AJAX, and found ways in which to ensure that the content is visible to search engine spiders.

In other words, the solution lies in being aware of the problems that SEO for an AJAX application would pose, and to counter the same during the construction stage. For instance, in the first load of your AJAX application you must include optimized elements like TITLE and headers. Also ensure that your rewrite your url in the form of a fixed address which the search engines must be able to index and therefore rank Yet another way out is to create as many internal links as possible. Keyword specific inbound links that point towards a specific section, not just the homepage of the website, would also be beneficial.

AJAX saves time that is otherwise spent on refreshing or reloading a page. SEO makes sure that all the hard work that is put in by writers, designers, and developers pays off and the target audience is able to reach the website – their desired destination. The importance of both AJAX and SEO cannot be undermined. And their significance is such that no website owner would want to compromise to make use of one and forgo the other. The co-existence of AJAX and SEO does not seem like a distant dream at the moment. If new technology creates roadblocks for existing techniques, it also often makes way for newer techniques to flourish.

patterns

Patterns being patterns, theres not a lot of unseen information here. Patterns are just a concise way to represent the knowledge embodied in the many AJAX applications that are out there. The point is to discover best practices by investigating how developers have successfully traded off conflicting design principles. AJAX is all about usability, so the patterns focus particularly on delivering usability in the face of constraints, most notably: user capabilities and expectations, bandwidth limits, the stateless nature of HTTP, the complexity of JavaScript.
AJAX is a new term, but XMLHttpRequest and related technologies have been around for a while. I know that, but the introduction of a single umbrella term nevertheless constitutes a tipping point which is forcing web development to move heavily in a certain direction. AJAX is only a name, but names can be tremendously important.

these are some points……..
Minimise traffic between browser and server so that the user feels the application is responsive.
Be clear on the interaction mode being used – regular HTML versus AJAX versus desktop application so that the user can predict what will happen next .. no surprises.
While avoiding confusion, borrow from conventions of HTML and desktop applications so that the user can rapidly learn how to use your application.

Introducing the ASP.NET Ajax Framework

Ajax is a popular technology that is used in many different ways on the World Wide Web. It has become a technology of choice for building fast and responsive user interface. This artical takes a brief look at the features of some of the more widely used ASP.NET Ajax frameworks.
The What and Why of Ajax

A simple feedback of AJAX for beginners

Website script holds large importance as far as popularity and usage convenience are concerned. As an innovative web language AJAX may not be very popular as it has come quite recently as compared with other web languages which have been around for last 10 years or more. For beginners a quick feedback of AJAX can be helpful.

AJAX is really faster in its application as it does not need connection to server every time you ask for the information. Call back process for required information from users is capable enough to avoid sluggishness of page view. Data updation has been made quite simple and there is no need to review the entire contents. The system can select the bits to update. AJAX uses those scripts which are normally supported by all major browsers.

If you are planning to develop a new website, you can try AJAX. Online tutorials are available to get basic start up guidelines also.
