The XML is considered as the very special language which is capable to label the information content. The data from the structured and semi structured documents can be labeled in this way. The query languages are capable to display the intelligent use of these XML comfortably. In this way the queries can be employed across all sorts of data. The data which are physically stored in XML and stores as XML can be utilized in this way. The language which satisfies these specifications is generally known as XQuery languages. Thus these Query languages

In 1977 and 1978, two Israeli researchers, Jacob Ziv and Abraham Lempel worked on a set of compression algorithms, which were later named LZ77 and LZ78. Later, in 1983, Terry Welch from Sperry (which later merged with Burroughs to form Unisys) developed a very fast variant of LZ78 called LZW. Welch, together with two IBM researchers, Victor Miller and Mark Wegman, filled for a patent for LZW.
At the same time, Compuserve, specifically Bob Berry, was designing a new algorithm for a compressed image format, where they used the LZW
In order to ease the development of devices with visual and voice interfaces for PDAs and other handheld devices, the Multimodal Toolkit and Rational Application Developer can be used. By using these products one can minimize the skills and time needed for creating complicated programs that use XHTML+V(XHTML + VOICE) on compatible devices.
XHTML+V is a new technology, that combine XHTML and voice interfaces on small devices, like PDAs and tablets. It is accomplished by combining different web standards, such as ECMAScript, JavaScript,
