In this project, we are providing accuracy and improving performance of cloud transactions in distributed transactional database system deployed over cloud servers.

Data transfer from one system to another means data will be transferred from system to database through third-party service, this third party provide the service of the transaction manager.

A distributed transactional data stored in database has access to one or more systems or suitable users (it is not system to system connection but it is database to user, client and cloud server connection). The transaction manager checks if the users, client have the privileges by checking their credentials and based on that he gives permissions This is called as host connection (Cloud server) for data accessing.

Storing the data in to cloud server means it is a global storage any one can access after checking the policy based authorization system which protect the sensitive data. It enables only suitable users to access the data.

Two-Phase Validation Commit (2PVC) protocol ensures that a transaction is safe and secure by checking if the user is authorized or not and then checks again if he has permissions or not. This improve the security and performance.
