When should I use SQL vs NoSQL?

Question

SQL databases are better for multi-row transactions, while NoSQL is better for unstructured data like documents or JSON. SQL databases are also commonly used for legacy systems that were built around a relational structure.

When should you use NoSQL over SQL?

If your data is very structured and ACID compliance is a must, SQL is a great choice. On the other hand, if your data requirements aren't clear or if your data is unstructured, NoSQL may be your best bet. The data you store in a NoSQL database does not need a predefined schema like you do for a SQL database.

When should you use a NoSQL database?

NoSQL is extremely useful for unstructured or very large data objects such as chat log data, video, or images. That is why NoSQL became particularly popular with internet giants like Microsoft, Google, Amazon, Meta (Facebook), etc. Some popular NoSQL databases include: MongoDB.

When use NoSQL vs MySQL?
