What are the differences in encryption between NoSQL and SQL databases?

SQL databases typically use structured data and often rely on traditional encryption methods like AES. NoSQL databases, on the other hand, can handle unstructured data and may use different encryption techniques, including field-level encryption.

Can you explain how field-level encryption works in NoSQL?

Field-level encryption in NoSQL allows you to encrypt specific fields within a document rather than the entire document. This means sensitive data can be encrypted while other data remains accessible in plaintext.

Are there any performance impacts when using encryption in these databases?

Yes, encryption can introduce some performance overhead, especially in NoSQL databases where data is often accessed in a more flexible manner. However, the impact varies based on the encryption method and the database architecture.

Which database type is generally considered more secure?

Security depends on various factors, including implementation and use case. Both SQL and NoSQL can be secure if properly configured, but SQL databases often have more mature security features.
