location on a separate server.replicas can be kept in sync with the source data continuously or at scheduled intervals. One-way synchronization and bidirectional synchronization are possible. Replication can even be used to keep several datasets in sync with each other. at the first level, I'll cover basic replication components and describe how they work together to replicate data and change data. We'll also look at a detailed example of setting up

Certificates and asymmetric keys encrypt data using the internal public key at the database level, and data is decrypted using a database-level internal private key. Symmetric keys are relatively simple, and they contain a key for both encryption and decryption. In this case, encrypting the data with a symmetric key is faster and more appropriate for large data.
