Abstract— In this paper, our research objective is to develop a
database virtualization technique so that data analysts or other
users who apply data mining methods to their jobs can use all
ubiquitous databases in the Internet as if they were recognized as a
single database, thereby helping to reduce their workloads such as
data collection from the Internet databases and data cleansing
works. In this study, firstly we examine XML scheme advantages
and propose a database virtualization method by which such

Marketing in Transition - Concepts & Practices

Since the beginning of the phenomenon of the marketing, there have been many changes in the business scenario, practically and academically. Over a long period of time, different concepts and conceptions have come into being and have been replaced by some other ones, yet the two aspects that have remained unchanged are marketing and customer. Marketer plans and directs all the efforts towards the customer, and they know it intrinsically that their su ....etc

Object-oriented techniques achieve further reusability through the encapsulation of programs and data. The techniques and mechanisms we shall discuss here are primarily concerned with paradigms for packaging objects in such a way that they can be conveniently reused without modification to solve new problems.

Instantiation and Object Classes
Instantiation is perhaps the most basic object-oriented reusability mechanism. Every programming language provides some built-in data types (like integers and floating-point numbers) that can be instant ....etc

FUEL CELLS-Evolving Concepts and Developments

Introduction
Output of conventional batteries are limited.
They are polluting.
Continuous operation results in fall in efficiency.
Output not stable under long durations of operations.

Fuel Cells
An Electrochemical energy conversion device
Produces electricity from external fuel and oxidant.
Can operate virtually continuously as long as the necessary flows are maintained.

General Structure
Two electrodes sandwiched around an electrolyte
Hydro ....etc

VIRTUAL DATABASE TECHNOLOGY FOR DISTRIBUTED DATABASE (DATAMINING)


ABSTRACT:
The main aim of this project is to take the results of different database and to store it in a single database so that there will be no need for the user to search for the specific item on different databases. In this application mainly what we are doing is collecting the data from different search engines while searching by the different user saving in one database so whenever user is sea ....etc

Virtual Database Technology for Distributed Database



introductionn

In a large modern enterprise, it is almost inevitable that different portions of the organization will use different database management systems to store and search their critical data. Competition, evolving technology, mergers, acquisitions, geographic distribution, and the inevitable decentralization of growth all contribute to this diversity. Yet it is only by combining the information from these system ....etc

Web database publishing is a new way to publish information electronically. A typical Web database publishing system has a Web browser as its user interface, a database server as its information store, and a Web server connecting the two. The basic idea of this project is to use JDBC to search databases directly from an Internet Web browser. The database is kept on an NT server. JDBC is used to interact with Web pages. This project uses a simple interface to help the administrator update the database on the Web server. Some security issues are ....etc

INTRODUCTION
Since the conventional solid gun propellants have reached the saturation level in terms of energy output, a need exists for the development of high performance propellants for futuristic gun ammunition to propel hypervelocity projectiles. Hypervelocity guns are the guns having muzzle velocity in excess of 2000 m/s. Modern tank guns have muzzle velocity in the range of 1600 “ 2000 m/s. With continuous improvement in armour technology, improved weapons with high muzzle velocity are under ....etc
