PROJECT OVERVIEW

A heterogeneous distributed database environment integrates a set ofautonomous database systems to provide global database functions.

In our project we will provide a simple way to connect different Databaseproviders/servers.

The client is unaware of how the data is being sent & where.

The different database platforms that cannot understand each others

language can communicate through the Middleware.

Middleware provide web services to the user & bank using soap protocol,soap act as a interface between client & bank server.

Gathering data from different data sources, merging, sorting & cleaningdata & preparing output to send is handled by Middleware itself.

Manyorganization find it difficult to keep their databases and the databaseserver in a standard format.

It becomes very difficult to communicate or perform migration of data or

perform cross DB server transaction with a single interface.

HDDBMS is a simple solution to the above problem allowing the user to do

everything and keeping abstraction level as high as possible to the user.

FUTURE SCOPE

Connected via the internet using dedicated leased lines.

At present the project is implemented for a single banking environment which would be

further extended by connecting several bank

The entire system would require a very large security but would solve a lot of issues

faced by banks and customer by allowing a customer to migrate to another bank with

ease or perform cross bank transactions.

Protocols will also be designed to allow customer to access their accounts from theirmobile phones by providing additional security and smaller sized web pages.
