Abstract
The objective of this project is to explore a method to integrate multiple heterogeneous databases like MySql, Oracle, Sybase, Postgre, by taking the advantage of some of the latest Web technologies.It provides a global interface for these databases, accepts a query from the user in a natural language format(english), translates this query into SQL using a translator, then retrieves data from the database, displays the result to the user and convert it into a unified format. The unified format here we are using is XML.

Abstract
Databases and XML offer complementary functionality for storing data. Databases store data for efficient retrieval, whereas XML offers an easy information exchange that enables interoperability between applications. To take advantage of XML's features we can convert database tables into XML documents. We can then use XML tools with such documents for further processing. For example, XML documents can be presented as HTML pages with XSLT style sheets, can be searched with XML-based query languages such as XQL, can be used as a data-ex ....etc

XML is a popular meta-language that facilitates the interchange and access of data. However, XML's verbose nature tends to increase the size of a data file by as much as ten-fold. In this seminars, we give a brief introduction to data compression followed by a review of various compression strategies designed specifically for XML data. We then present two novel XML compression techniques, AXECHOP and TREECHOP. AXECHOP uses a grammar-based approach that exploits the significant structural redundancies within XML documents, while TREECHOP support ....etc

As XML becomes a predominant means of linking blocks of information together, there is a requirement to secure specific information. That is to allow authorized entities access to specific information and prevent access to that specific information from unauthorized entities. Current methods on the Internet include password protection, smart card, PKI, tokens and a variety of other schemes. These typically solve the problem of accessing the site from unauthorized users, but do not provide mechanisms for the protection of specific ....etc

A NEW MODEL FOR DISSEMINATION OF XML CONTENT

Abstract: The paper proposes an approach to content dissemination that exploits the structural properties of an Extensible Markup Language (XML) document object model in order to provide an efficient dissemination and at the same time assuring content integrity and confidentiality. Our approach is based on the notion of encrypted post order numbers that support the integrity and confidentiality requirements of XML content as well as facilitate efficient identification, extraction, and distribution ....etc

A Parallel Approach to XML Parsing



Abstract”a language for semi-structured documents, XML has emerged as the core of the web services architecture, and is playing crucial roles in messaging systems, databases, and document processing. However, the processing of XML documents has a reputation for poor performance, and a number of optimizations have been developed to address this performance problem from different perspectives, none of which have been entirely satisfactory. In this paper, we present a seemingly quixotic, but novel ap ....etc
