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

SQL databases are typically vertically scalable, meaning you can increase the capacity of a single server. NoSQL databases, on the other hand, are designed to be horizontally scalable, allowing you to add more servers to handle increased load.

Can you give examples of when to use SQL over NoSQL?

Sure! Use SQL when you need complex queries and transactions, like in banking systems. NoSQL is better for large-scale data with flexible schemas, like social media platforms.

What are some common NoSQL databases?

Common NoSQL databases include MongoDB, Cassandra, and Redis. Each has its own strengths depending on the use case.

How do I decide which database to use for my application?

Consider factors like data structure, scalability needs, and the complexity of queries. If you need strong consistency and complex transactions, go for SQL. For flexibility and scalability, NoSQL is a better choice.
