Advanced Web Application Development Tools - XOOPS

XOOPS is a new technology meant for web developers. It is acronym for Extensible Object Oriented Portal System. It is a web application platform that provides tools for online application development. It was developed by organization known as XOOPS Project and is an open source content management system. It is written in PHP.

The name might suggest it as a Portal System but it is mainly used as web application platform. What Extensible Object Oriented Portal System provide is template for every type of website development. It has a modular architecture and developers require installing all the required modules. Once the installation is done it allows developers to customize, modify, applying theme and maintaining website with regular updating.

It has been one successful platform receiving many awards and accolades. It has gained a reputation in PHP based Content Management System forte and is considerably rated among top % platform since 2008.

XOOPS provide database support using Relational database, currently MySQL. It also has advanced control on the access. The access control allows administrator to manage user groups and grant them with only necessary rights. The right and facilities can be blocked by administrator.

Every single module can be handled separately including installing and uninstalling. It has different administration for every module that looks after activation and deactivation. Every module thus separately manages the comment, permissions, access controls and notifications. Along with this administrator can specify specific permission to users as well.

Since XOOPS is open source and released under the terms of GNU General Public License, the development in it depends of the contribution from worldwide communities. It is one of the best tools and web application platforms and can be developed further.

Optimizing Graphics for Web development - WebGL

There is always an advancement taking place in web development. WebGL is one such introduction to the already existing development features. WebGL stands for web Graphics library. It was introduced and managed by a group named Khronos Group. It was developed originally by Mozilla foundation and is used for inducing 3D graphics.

WebGL is based on Java Scripts and hence also known as Java Scripts API. It is used to induce 2D and 3D graphics. It is based on the Open GL ES that provides gaming graphics. It is compatible with all web browsers. It is in conjunction with HTML and hence doesn't require any plug-ins to use it in web page.  It might seem as easy to implement but is difficult to learn. It is executed on Graphic Processing unit, which is java script port meant for Open GL, which has its own set of API for game development.

Implementation:
Since it is mainly used for game development, it consist of both control code which, has to be using Java Scripts and also code for shading purpose. The program thus generated is executed on Graphic Processing Unit. This graphic library makes use of HTML5 canvas element. It is accessed using the DOM interfaces i.e. Document Object Model interfaces. It also comes braced with Automatic Memory Management which is one of the features provided by Java Scripts.

Tools like Blender or Autodesk Maya provide an alternative to programming. They are the content creation tools which allow creating scene. The scenes thus created using such tools are then exported in the graphic library. There are tools for exporting like Inka3D which is meant for Maya.

Introduction to jQuery

Developing a web site requires updating skills and use of new tools. While developing dynamic web pages, it is also mandatory to consider size. jQuery is a library and is open source library. It allows adding advancement in pages with help Java. This library was thought of due to popularity of Java Scripts. Though the scripting language was popular, it had some shortcomings. It was very basic language and has no features offering advance modification and any special effects. It was also incapable of animation. Cross browser incompatibilities was main issue that was faced using Java Scripts. All these problems needed solution and hence jQuery came into picture.

jQuery provides easy solution for every issues faced with Java Scripts. It has also maintained the benefits of scripting language by offering light weight libraries. The library strengthens the scripting language by making it cross browser compatible. It also offers advancement to the basic language. There are many components available for modifications in this library. It is compatible with JavaScript Object Notation (JSON). It simplifies the client-side scripting.

It is very easy to install and use jQuery. All that is needed is to download the library package and import it in web page code. There are two versions of library package available minified version also known as min and development version. It is small yet efficient and development version makes it easy to read and debug. Following is the one method of importing library.

<script type="text/javascript" src="jQuery-1.4.1-min.js"></script>

This will upload the min version library package and is ready to use.

What is the difference between software and hardware?

Hardware and software are related to computers and are totally different in meaning. They are dependent on each other because software or hardware cannot function alone.  

Hardware:

Hardware is a set of physical devices connected to computer which one can touch. It contsists of CD-ROM, CD-RAM, motherboard, Central Processing Unit, hard disk, sound cards, video cards etc. These are the internal hardware devices while keyboard, monitor, mouse, webcam, scanner, printer are outer devices. Hardware devices are roughly divided in to two types.

Input device and output device. 

Input device are those with which commands are given to computer. Like keyboard, mouse, joystick, scanner etc. Output devices are those in or on which we get output of our commands. It consists of monitor, sounds, printer etc. We can get output in soft copy and in hard copy as well. Result which we can see on monitor, can hear on sounds is type of soft copy. If we print a document and get paper print it is a hard copy.

Software:

 Software is programs or set of instructions which have to be installed on computer. They cannot be touched. Software is categorized in three types. 1. System software 2.  Programming software 3.  Application software. 

1. Application software: Application software is suite of programs to perform a specific task. Like accounting suite, graphic suite, office suite 

2. System software: It is known as an operating system of computer. Without operating system pc is like body without soul. There are different o/s available in market viz. windows, linux, macintosh, solaris, ios etc.

3. Programming software: are set of ready-made programs like MS word, Excel, Photoshop etc. These programs again are divided in two various categories like database programs, editing programs, word processor, spreadsheet etc. 

What is an operating system?

Operating system is like soul of computer. It is a significant part of system. It is actually a software program which serves as connection between hardware devices, programs and computer systems. Your hardware parts will not work without the command of your OS. Ready-made applications and programs are useless if the pc has no operating system.

Operating system manages all the folders and files in computer. It accepts instructions from the input devices like keyboard, mouse, it gives output of the task performed in the form of soft copy and hard copy. OS controls the other attached devices like printers, Pen Drive, Webcam.

The operating system can be categorized in following types.

1. Multiprocessing: This supports any program to operate on more than one CPU.

2. Multitasking: More than one program can be run with this system. With Windows 7 user can work on unlimited programs.

3. Multi-users: Hundreds of or thousands of user can work on this using this system.

4. Multi-threading: In this type O/S allows the various functions of the one program to run simultaneously.

There are many brands present in market viz. Windows, Linux, UNIX, ios, macintosh, solaris etc.  Windows is widely used and has been developed by Microsoft company. There are various versions of Windows like Windows 98, Windows XP, Windows 7, Windows 8 etc. These systems are compatible with the personal computers. MacOS and iOS are developed by Apple Company and compatible only with Apple PCs and iphones respectively. Android is operating system owned by Google and used for mobile phones.

 

What is markup language?

Markup language is method in which the text is annotated or commented so that the document is differentiated and the computer can manipulate it. It is readable by human beings because the text is written in markup tag. When you write the text to be displayed on internet, you need to differ between that text and instructions. So in simple terms markup language is a set of words and tag symbols which give instructions on how that particular document should be displayed in output.

There are broadly three types of markup languages; 1) Presentational.  2) Procedural 3) Descriptive.  Several markup languages like HTML (Hypertext Markup Language), XML (Extensible Markup Language), XHTML (Extensible Hypertext Markup Language), MathML (Mathematical Markup Language), RTF (Rich text format), SVG(scalable vector graphics), SGML (Standard Generalized Markup Language), GuideML (Guide Markup Language) etc are used. In these languages tags are used to manipulate code. Markup language is created by typing code manually or by using editor. Text editors, Object editors, WYSIWYG and WYSIWYM are some of the examples of the editors.

HTML is most commonly used Markup language. It is used to build website. It helps to define how the text, images should be displayed in web browsers. It is one of the standard languages rated by W3C. It uses angular brackets as its tags to define code. E.g. <b> tag is used for to bold the test; <i> tag is used to make text italic; <u> for underline, <img> is used for image, <font> for size and family of font, <p> for paragraph, <marquee> for motion of the text etc.

About Scripting Languages

Scripting languages are based on high level programming language. High level languages are more compatible to human language than system and it is very useful to system hardware to recognize the various instructions. C, C++ etc. are the example of high level language and all these language are converted into machine language via interpreter and compiler. Scripting means a programs that are written in scripting languages are not executed in front of specific period for particular system. As a substitute scripts which are made in plain text get interpreted into system compatible code when the program runs.

We can add the interactivity into web pages using scripting language. We can use it in many places in our web pages to carry out various cyclic jobs like filling the content in web based form along with users.

JavaScript is popular web scripting language and we can use it with HTML language to improve the functionality of web pages. We can use java scripting with HTML many times to perform some action such as to check validation of input which is put by user, playing audio and video file and image sliding etc.

There are various browsers and they are Internet explorer, Firefox, safari, Google Chrome and Opera etc. all are interpreting these scripting languages along with languages which are used to build web page. In other way this can be done at server side means these scripting are run at server. In server base scripting common gateway interface allow client to execute the scripting located in web server.

File Application Programming Interface

 Web site is meant for sharing of the information. It is observed that lot of data is sent, received and shared through the Internet medium. There are different ways of sharing information over web, those are:

1.    Including it as Hypertext: Hypertext is the text included directly in the HTML format in the page code. Information here is visible to everyone who accesses the web.

2.    Mailing: This method allows the data to be sent as a part of mail. The information is private and is between sender and receiver.

3.    Sharing on Social networking site: This has emerged as easy way of sharing information with a group of known people. It ensures privacy as well as allows uploading files.

File sharing is one most necessary facility. It is utilized by large amount of people. This is done by using File Application Programming Interfaces also known as File API. They allow access to files on the local system. This is a kind of application that uses Java script to provide access to files. It has to be compatible with different browsers. Most common example of such application is FileReader. It is compatible with Chrome, Firefox, IE 10 and opera.

This application creates a file object every time it is activated. It provides interface for user to programmatically select the file on the local system. The application accesses the file data and thus displays the size of it. It is most commonly used for uploading images. An advance API will allow dragging and dropping of the files.

Programming such application can start with use of simple <INPUT> tag and using it with type attribute specified as file. Eg: <input type=”file”>. This is then further enhanced by adding different features. Dragging and dropping feature is possible with HTML5 where <input> tag is replaced with <div> tag.

About Information Architecture

Developing website is not an easy task. It is necessary to understand how the website must look. Information architecture basically helps in organizing the website. It provides the basic idea about what pages to add in site. It specifies the flow of information as well as sequence of pages displayed. It is the duty of developer to ensure that a viewer is not lost while viewing the site. Data in a site has to be accurate, should not be repeated and consistent. Viewer must understand which page next to access for continuation. Thus information architecture involves following steps:

1.      Accessing Content If Existing and Working on Needed Content: When site is already developed or partially developed, it is necessary to make sure other information is in sync. For this we need to go through the previous work and then continue with new development. For new site, it is mandatory to consider the data to appear and its effectiveness.

2.       Organizing the Pages: For most important job of any developer is to arrange the several pages across site. The pages must proceed in sequence. The sequence is decided by the information a page holds.

3.       Instructions for Accessing site: There are no such specific instructions. Instructions are generally the tags or topics. Pages are categorized and arranged according to topics. Links for pages are managed so that site won’t look messed up.

4.       Navigational Structure: Navigational structure specifies which page to open on Next and Back keys. This depends on what page is currently accessed. Navigational structure must be managed well for site to not jumble its viewers.

Organizing information across site will help viewer find the required information easily. This will provide them with better experience. This also improves the total number of views and help in acquiring better page rank.

Standards for website design and development

People have been using every type of medium to promote and sell their products and services. Yet Internet is the best medium for this.  Attractive and catchy websites can pull attention of consumer towards their company thereby increasing their sales. However there are some standard for designing and developing websites.

There are not any obligatory web standards. Anybody can design and develop site according to his own initiative. However following the recommendations of institutes like W3C (World Wide Web Consortium), ISO (International Organization for Standardization), ECMA (European Computer Manufacturers Association), ensures the quality of sites, lowers the cost of production, makes sites accessible to most of the people and on most of the Internet devices. They require less bandwidth. They are extensible, easy to maintain and compatible with most of browsers.

There are following web standards.

Structural and semantic languages: Developer should use structural and semantic languages like HTML, XML, and XHTML.

Presentation Languages:  CSS which stands for Cascading Style Sheet is a presentation language. There are three levels of this.

Object Models:  DOM stands for Document Object Model. Again there are three levels of DOM.

Scripting Languages:  ECMA which is advance version of JavaScript.

Additional Markup Languages:  Mathematical Markup Languages like MathML 1.01, MathML 2.0.

These were the languages and other aspects recommended by W3C to build standard website.

As written above the first thing is the code on site, it should be validated. The code doesn’t mean only HTML but also XHTML, CSS, JavaScript. The validation of code means it should be according to definition of doctype. The code should be semantically correct. It means each element in web page should have it’s conform value and purpose. Following these standards helps Google and other search engines to properly understand the each and every part of web page’s code. It provides great help for SEO.

Asynchronous JavaScript and Xml (Ajax) Technology

Ajax is assembly of correlated web development tools and which is used on the client side application to build asynchronous application. The application which is developed using Ajax tools that can be send and retrieve data to and from the server without disturbing the any other part of same page of that web application.

Ajax is a collection of multiple technologies. In which we should do the mark up and style the information using HTML and CSS tools. We can develop a web application in which information exchange asynchronously between server and browser using the concept of JavaScript and XmlHttpRequest object.

              

Figure: Comparison between classic and Ajax based web application model. It can reject the start and stop environment of communication on web application by hosting the concept of Ajax engine between the user and web server. The whole process looks similar to putting new layer in application and that takes longer time to react. This process loads only particular section of web page instead of whole page. When session is started the web browser loads

Ajax engine which is built by using JavaScript and frequently put left in unseen frame. When we work on client side programming at that time we cannot access the function of server side. But this is possible when we uses Ajax technology. In this technology we can access server side function by using page method which is built in JavaScript.

Most of the Google products are developed using Ajax Technique and they are Orkut, Google map, Google suggest and Google groups.

Why a Web site?

Web is connectivity through Internet extends across the globe. Invention of this technology had helped human race in every field. It was observed before this invention that people were unaware of trade and business across countries. It was difficult for ordinary people to reach beyond their own cities. This network has helped people getting aware and provided recognition.

With all this advancement it was necessary that business and work change according to the requirement. Since people were now able to reach remote location virtually without traveling in real. For this it was necessary that the data and the information to have hyperlink. Web consists of data transported over hyperlinks. These hyper links are obtained once a person loads all the required information on website. The website acts as connection. These web sites are developed depending on the purpose of use and uploaded over servers. The server is actually a system meant for hosting website and has some IP address which is used for its recognition across Internet.

Web sites provide easy access to online business ventures. It allows people across web to get basic information about you from anywhere in world. Thus it improves your visibility and also your improves cross country business. Website had to be functional and well designed for easy access. The links must have accurate information.

In today’s time it is important for companies to have well designed and developed web site to represent them over Internet. Your business website also carries the service provided, location and contact information, for people who are interested in approaching. A good website always gives good business.

Designing & Developing Website

Developing a website is easy said, than done. The work needs information about how to initiate.  The languages used for the purpose are known as Markup languages. Before you start on with the task, you must take care of requirements. The concept should be clear much before the whiteboard stage.

There are various Markup languages to select from like Hyper Text Markup Language (HTML), Extended Markup Language (XML) and Standard Generalized Markup Language (SGML) etc. These languages require text editor for development and formatting purpose. The file thus created over text editor is to be saved with respected markup language extension.

Markup languages define tags for related formatting. They are incapable of generating results and hence for further coding either VB or Java are infused.  There other languages like PHP (hyper text pre-processor)  are strong enough to format and code simultaneously.

There are many tools available for aiding the development. These tools are actually the development environment. There are varied types including the one that provides framework and theme to the one where in we have to develop everything from scratch. The site development involves managing content and data queries both.

Data queries are generally meant for passing down the data across the pages or for retrieving it from storage. These queries have to be effective enough to get the required data without delay. To perform such queries it is necessary to have a storage. The storage mostly used is called the database. It is used to store the data acquired from site. This makes processing easy and fast.

Developing a site solely depends on the requirement. If the site is static informative, it will have simple functionality. If site is dynamic and information processing, then it will be complicated.

Website Design for Mobiles

The design of website of your business, organization and any other related services is most important. Similarly design of web site for mobile phones, iPhones, tablets is important as well. This is because now a days most of the people of the world use mobile phones, iPhones, tablets etc.

If the website already exists then you have to make changes in it so that it will easily available on smartphone or any other device which have smaller screen display then desktop or laptops.

When designing website for mobiles or any other device that has smaller screen than desktop computer or laptops: 

1.    One column design: Most of the web pages have more than one column of content and it is difficult for user to read and scroll. But the single column design is easy to read and scroll the content of the web page.

2.    Less Content of information: The content of your web pages should be limited and meaningful so that user can easily read and understand the concept of it.

3.    Important and limited images: You should use limited and important images to build your website. But at the time of development you should optimize all this images in 8KB or below 8KB. Before embedding in your website make the entire images small in width. This way all images will easily display on mobile phones or any other small size devices.

Importance of off page optimization in SEO

The mixture of on page and off page optimization is the method of search engine optimization. The off page optimization is most likely essential to increase the rank of website. The main SEO and whole process are executed outside the html code and web page.

It is beneficial to improve your SEO ranking by adding more and more links from various higher ranked websites. The social media is an important tools for business related website over Internet.

There are various most popular tools are available that provides better back links and these tools are:

1.    Directory submission: The process of directory submission is also very important to improve our website rank. In this technique we can add our website in higher rank web directory in proper category. We can do this by adding our website URL and information related to our website in web directory.

2.    Social networking: It is the process of exchanging the information between each other and creation of professional and social contacts. Facebook, twitter, Google plus etc. are the part of social networking.

3.    Social bookmarking submission: It is a technique of storing bookmarking on web by marking it with meaningful Meta keywords which is most commonly helpful to share with other.

4.    Blog posting: It can be done by single person or rarely by small group. It consists of article on specific topic which is related to our website. The content of this article must unique and meaningful. If the content is meaningful and easy to understand visitors will read the blog and make it popular.  They will put the good comments and message on our blog.This is helpful to improve the SEO rank of our website.
