choices for enterprises. Yu sicheng, vice president of Oracle and general manager of technology in Greater China Oracle Database 12c adopts a multi-tenant architecture. By separately managing data content in different tenants, the independence and security required between tenants can be ensured. While retaining the functions of each tenant, it can achieve unif

utilization of server resources and saves the time and work required for database upgrade, backup and recovery. The multi-tenant architecture provides almost instantaneous configuration and database replication, making the architecture an ideal platform for database testing and development cloud.
