What is JavaScript 

Javascript is a client-side language with processing engine embedded in web browsers. JavaScript programming was originally invented as part of web browsers. As a client-side language, JS allows users to interact with web pages and load the content without refreshing the web page.

Originally, JavaScript was developed in Netscape under the name LiveScript. The choice of “JavaScript” name caused a misconception that the language is a version of the programming language known as JAVA. However, although both have some common syntax, JavaScript and Java are different languages. JavaScript was developed at Netscape, while Java was originally developed at Sun Microsystems. The syntax of JavaScript was influenced by one more widely used programming language C. JavaScript is a multi-paradigm, prototype-based, object-oriented, imperative, and functional scripting language, not a real programming language.

Google Chrome extensions, Opera's extensions, Google Desktop Gadgets, Apple's Safari 5 extensions are implemented using JavaScript. Outside of web browsers and web pages, JavaScript are be used in PDF files as well as for desktop application creation.

JavaScript Features

Javascript brings more dynamic functions and features to HTML. The most common use of JavaScript is writing functions that are embedded in HTML and interact with the Document Object Model. Let us look at just some JavaScript programming features:

 • Loading the content via AJAX without reloading the web page
 • Manipulating, moving, resizing, etc web page elements, animation, visual effects
 • Interactive content using and developing, game development, audio/video
 • Performing web form validations, as well as calculations
 • Other

The latest version is JavaScript 1.8.5. jQuery and Prototype are popular JavaScript libraries. The development of Ajax enhanced the interest to JavaScript language using and implementation.

Asynchronous JavaScript and XML: What Is AJAX?

AJAX is a combination of web development and programming technologies for creating fast-loading interactive websites and web applications based on XML, HTML, CSS and Java Script. Using Ajax technologies professional web designers and web developers are able to create modern web applications with cutting-edge accessibility and interactivity.

Developing Ajax Web Applications

AJAX stands for Asynchronous JavaScript and XML. The technology allows developing better and quicker applications. The key is that Ajax web apps retrieve data from a server asynchronously without interfering with the display of the existing web page. In other words, the asynchronous nature of AJAX allows the browser to exchange data with a server while the user is doing other things. So, the user does not have to wait for the entire web page to refresh. 

Typically, the interaction between the user and the server is synchronous. It includes the processes requiring a lot of user waiting. The user accesses the web application. Then, the request is processed by the server. The server sends data to the browser while the user waits. AJAX acts independently of web server software. When the user clicks on an Ajax-based application, the page shows what they are asking for without reloading the entire browser page. Ajax uses XHTML for content, CSS for presentation and JavaScript for displaying dynamic content. 

One of the perfect examples of Ajax application is Google Maps. Google was the first to use web development technique "Ajax". Besides mapping applications, examples of AJAX apps are chats, e-mail applications, real-time searches, shopping cart apps, etc.

Building websites based on Ajax: 

• XHTML and CSS browser-based presentation 
• Interaction with the page through The DOM
• Data stored in XML and received from the server 
• Data retrieval with XMLHttpRequest in the browser 
• JavaScript 

The most appealing benefit of Ajax is that it works within the browser and allows for the interaction with the application and the user to go independently of the interaction with the server. But, remember that AJAX applications will not work in web browsers that do not support JavaScript. A mixture of web design and development techniques, AJAX has become an integral approach used in modern web development.

To publish and update the static website you do not need any special web design and web programming experience.

Dynamic websites are typically a larger website that is database-driven. Dynamic sites usually include hundreds of web pages with huge amount of different content. Dynamic sites are connected to a database where the content is stored in an organized way.

What Is MySQL, Why Use MySQL Database

MySQL-database
Website database is like a file storage cabinet. Any high-volume websites or web-based business needs a reliable database to monitor business processes, store information and gather all website data. One of the most popular databases used on modern database-driven websites contain websites is MySQL. This is a very powerful and efficient database system that runs as a server providing access to a number of databases. MySQL is open source and falls under the terms of GNU General Public License.

The world's largest websites like Wikipedia, Facebook, Twitter, Flickr, YouTube are driven by MySQL database

What is a Database

Database is an organized collection of data. The database gives websites high functionality, allows monitoring data accuracy and manipulating a big amount of content. The database is maintained through Database Management System (DBMS), a system of programs providing essential data administration tools and functions. The choice of the database for a website depends on the type and amount of data to be stored and processed. The content in the website database is usually managed by using a Content Management System (CMS). High-volume websites that include information about users, customers, products, transactions, and more data need a reliable web database.

What is MySQL Database

MySQL (often pronounced as "sequel") is a popular free database management system used on modern web applications. This open source database is used on Joomla, WordPress, Drupal, and other applications. MySQL database works on many different system platforms, including Linux, Mac, Windows, etc.

MySQL is a relational database. A relational database uses tables to store information. Each table contains data categories in columns and rows. Relational databases are built using a special computer language, structured query language (SQL).

Why Use MySQL

As an open source program, MySQL is customizable and allows you to add specific requirements to the server. MySQL is a client/server system. For client programming can be used programming languages like C, C++, Java, Perl, Python, PHP. For the building of MySQL database driven apps there are many application programming interfaces and libraries. MySQL can be executed under a number of operating systems like Apple Macintosh OS X, Linux, Microsoft Windows, Unix.

MySQL database offers absolute security and data protection. MySQL is equipped with SSH and SSL support and powerful mechanisms for ensuring that only authorized users can access to the database server. MySQL backup utilities allow for complete backup and recovery. MySQL database server can be configured specifically for a particular web application, whether these are transaction processing systems (TPS) or high volume sites that deal with hundreds of queries every day. 

Equipped with many tools and performance-enhancing possibilities, as well as easy to use and reliable, MySQL has become the database of choice for modern website development.
