Can you use NoSQL for relational database?

Question

Relational databases are table-based. NoSQL databases can be document based, graph databases, key-value pairs, or wide-column stores. Relational databases were built during a time that data was mostly structured and clearly defined by their relationships. Today, we know that data today is much more complex.

When should use a NoSQL database instead of a relational database?

When there are a large number of read-write operations on your website & when dealing with a large amount of data, NoSQL databases fit best in these scenarios. Since they have the ability to add nodes on the fly, they can handle more concurrent traffic & big amount of data with minimal latency.

How is relational data stored in a NoSQL database?

Relational databases rely on tables, columns, rows, or schemas to organize and retrieve data. In contrast, NoSQL databases do not rely on these structures and use more flexible data models.

Will NoSQL replace relational DBMS?

As we move into the future, the volume of unstructured data is going to grow, so NoSQL as a DBMS also has a bright future in the storage industry. But, it will not replace RDBMS, as the relational use cases are well managed by the relational models only.
