What is the difference between a relational database and a NoSQL database?

The main difference between relational databases and NoSQL databases is the way they store and manage data. Relational databases use a structured format, with data stored in tables, while NoSQL databases use a more flexible, document-based format. Additionally, relational databases are typically more rigid and require a predefined schema, while NoSQL databases are more flexible and can handle unstructured data.

Can I use a relational database for real-time data processing?

Yes, relational databases can be used for real-time data processing, but they may not be the best choice for high-volume, high-velocity data. In these cases, NoSQL databases or stream processing platforms may be more appropriate.

How do I ensure the security of my relational database?

To ensure the security of your relational database, you should follow best practices for database security, including using strong passwords, limiting access to the database, and encrypting sensitive data. Additionally, you should keep the database software up-to-date and apply security patches as needed.
