When should I use relational databases instead of non-relational ones?

When should I use relational databases instead of non-relational ones?

Relational databases are ideal for structured data with clear relationships, like customer records. Non-relational databases excel with unstructured data or when scalability is a priority.

Can you give me examples of when to use each type?

Sure! Use relational databases for applications like banking systems, where data integrity is crucial. Non-relational databases are great for social media platforms, where data types can vary widely.

What are the main differences in performance?

Relational databases often have slower write speeds due to ACID compliance, while non-relational databases can handle large volumes of data quickly, making them suitable for big data applications.

Are there any scenarios where I should avoid using non-relational databases?

Yes, avoid non-relational databases if your application requires complex queries and transactions, as they may not support these as effectively as relational databases.
