Abstract: Traditionally we have seen that ERP systems are developed using Row-oriented database system. Our project tries to implement column-oriented approach in development of ERP systems. The system which we are trying to develop is Employee Performance Review System. Modern software applications (ERP application in this case) are highly data-centric. As data is highly sensitive security is primary concern, we are trying to increase randomness of the encryption algorithms so as to increase the level of the data security. Loss of important data can affect business process. Hence we provide the data backup using cloud so that in case of application failure the important data needed for business decision making is not lost.

Keywords: ERP, Column-Oriented Database, Vertical Partitioning, Symmetric Encryption, Cloud Backup.
