When you firstly listen about Ajax as a new technology all what jumps to your mind is just “oops, I gotta learn again !!” , but if just you take only a snapshot about the hints introducing this technology you will discover that in term of that it

is not a technology that erase the others appeared before it but its a technology that enhance your abilities in the old technologies you were taught and gained experience using it years over years before , i feel satisfied when I know that because i still believe that we havent took all the advantages of the present
technologies we are still using , still the open source war producing more and more weapons and bringing the goods from the olds we always use .

And when we come into more details to explain “Ajax” , we must firstly include that the word Ajax stands for “Asynchronous Javascript and XML” , from this short explanation driven from th previous title , we can conclude that Ajax appears not as a standalone technology but in other way its a technology combining the previous once for more sufficient output , from my previous readings I was believing that XML is not just a huge technology as its inventors claim , it was just a markup language with something like an open source
declarations which offered the markup programmers a new facilities and brought out many technologies such as voIP to appear, but still we can see that XML cannot stand alone without another technologies to assist in producing its output , till the past years XML was just an intelligent data storage language utility , and by the help of other technologies like HTML and CSS it has found its way to the hands of the hungry developers , its ease of use was one of the reasons which allowed the new generations of technologies such as Ajax we are talking about right now to appear , Ajax was firstly developed by Google in year 2005 , Google was aiming by the introduction of this technology to combine the advancements of features beside the ease of use of the Javascript with the ultimate compatibility of the XML as a database system which  works with any other available data manipulation systems , plus its acceptance to any new declarations for data arrays , by the introduction of this technology , Google have found a new way to introduce an efficient  employment of the unused system resources of both Javascript and XML after they started to come nearer to their declining stage after a long maturity aera .
