What are the best practices for using SQL and NoSQL databases?

When using SQL databases, ensure to normalize your data, use indexes wisely, and write efficient queries. For NoSQL, focus on data modeling, scalability, and understanding the specific database's strengths.

Can you explain data normalization in SQL?

Data normalization is the process of organizing data to reduce redundancy and improve data integrity. It involves dividing a database into tables and defining relationships between them.

What are some common use cases for NoSQL databases?

NoSQL databases are great for handling large volumes of unstructured data, real-time web applications, and big data analytics. They're often used in social networks, content management, and IoT applications.

How do I choose between SQL and NoSQL for my project?

Consider the nature of your data, scalability needs, and the complexity of queries. SQL is ideal for structured data with complex relationships, while NoSQL is better for unstructured data and horizontal scaling.
