What is Ajax?

Ajax is not an invention or a new programming language, it’s a web development technique witch build based on old ones (JavaScript, XML, HTML, CSS). Ajax is stand for (asynchronous java script and XML), and this technique make your web site more flexible faster friendly and more interactive, Ajax became popular in 2005 when Google use this new technology.

What Ajax Can Do?

What if I want just only a part of the webpage to be process and in this part get back only what the client needs without reloading the hole page ?!! This is what Ajax can do, with Ajax java script can communicate with server using XMLHttpRequest Object, and can exchange data with server. when you want to get or send data from server using JavaScript we make a form and post this data but unfortunately its reload anew web page with http request now we can get data from server behind the seen without reload the webpage, he will stay in the current page and will not notice any thing happened behind the seen.

XML

XML Extensible Markup Langauge :

• Defien Structure Data in plain text.
• Markup langauge based in Tags.
• Subset of SGML.
• Edite and crated by text editor.
• Unlike HTML dosn't have fixed sets of tags.
• Fouccs in data and its structure but HTML focus in presentaion.
• Not only used for web pages.
• Unlike HTML ,XML isa case sensetive.
• Universal Data Exchange Format HOW?

Separation of Content and Presentation
With HTML, the actual data and its presentation logic are interleaved. HTML tags do not add any semantic meaning to the data content, but just describe the presentation details. This approach makes it hard to manipulate just the data or just the way it is presented. The Cascading Style Sheets (CSS), initiative made an effort to separate data from the presentation.

As XML makes no assumption about how tags might be rendered on the display device browser,
wireless cell phone, PDA, or whatever, but simply provides a means to structure data with tags we define. it is quite natural to use the same XML data document and present it differently on
different devices. This separation of data from presentation also facilitates easy access to the data.

Example Of XML File:

XML-based Languages
Already, many new markup languages based on XML syntax have been created to meet the needs of specific application domains ,some of them:

• SOAP
• SMIL
• SVG
• XForms

never make somebody your every Thing because !!when they are gone you have got NOTHING !!!

Swallowed in the sea

Swallowed in the sea Lyrics for my favourite band COld PlAy..........

You cut me down a tree
And brought it back to me
And that's what made me see
Where I was going wrong

You put me on a shelf
And kept me for yourselfI
can only blame myself
You can only blame me

And I could write a song
A hundred miles long
Well that's where I belong
And you belong with me

And I could write it down
And spread it all around
Get lost and then get found
or swallowed in the sea

You cut me down to size
And opened up my eyes
Made me realize
What I could not see
