These are special purpose devices and computers that just transfer messages from one network to another. Before we look deep into the topic Virtual LAN's, let us see the basic devices used in the network backbone. They are

1. Bridges.
2. Switches.
3. Routers.
4. Gateways.
5. Hubs.

BRIDGES :-Bridges operate at the data page link layer. They connect two LAN segments that use the same data page link and network protocol.

SWITCHES :-Like bridges, switches operate at the data page link layer. Switches connect two or more co ....etc

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
u ....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

ABSTRACT:- In the autumn of 1969, we decided to try a new approach to the design of a virtual machine operating system. Until that time, most installations using Virtual Machine Monitors merely ran operating systems that already existed for €œstand-alon use. Few, if any, installations had attempted to design and create an operating system that took advantage of its running environment. The Virtual Machine Monitor we were using was a highly modified version of CP-67 which was designed to operate on an IBM S/360 Model ....etc

VIRTUAL DATABASE DESIGNING



Proposed System

Proposed system i.e. VIRTUAL DATABASE DESIGNING simplifies the all cumbersome operations of original system. It simplifies all operations like DDL, DCL, DML, and TCL. It provides virtual interface to the user. Due to easy GUI user can perform the operations like creating tables, dropping table, creating views, applying constraints, renaming table names, inserting, updating, deleting etc in easy manner. This t ....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
