Should you choose a relational or NoSQL database?

Question

NoSQL databases don't require any predefined schema, allowing you to work more freely with “unstructured data.” Relational databases are vertically scalable, but usually more expensive, whereas the horizontal scaling nature of NoSQL databases is more cost-efficient.

Which is better relational or non-relational database?

Non-relational databases can store unlimited sets of data with any type and have the flexibility to change the data type. But relational databases work best when performing intensive read/write operations on small- or medium-sized data sets.

Is it best to use a NoSQL database?

NoSQL databases are able to store various types of data and do not need to be as structured as SQL databases. Hence non-relational databases allow for great adaptability and flexibility, making it a more suitable choice when handling large sets of unstructured and unrelated data.

When should I choose a NoSQL database?

Consider NoSQL databases when…1Your data is highly structured, and that structure doesn't change frequently.2You support transaction-oriented systems such as accounting or financial applications.3You require a high degree of data integrity and security.4You routinely perform complex queries, including ad hoc requests.

Why are NoSQL databases more useful than relational databases?

When compared to relational databases, NoSQL databases are often more scalable and provide superior performance. In addition, the flexibility and ease of use of their data models can speed development in comparison to the relational model, especially in the cloud computing environment.
