We've reached the end of this chapter and we have learned the details of the Data Guard protection modes and how to change the mode with all possible interfaces. The protection mode of the Data Guard configuration is an important consideration. Before designing the network, server, and disk infrastructure for the Data Guard installation, we should first decide the protection mode depending on the business requirements.

The next chapter will include information about role transitions in Data Guard. Also, details for performing switchover and failover operations will be covered for both physical and logical standby database configurations.
