What is a NoSQL database good for?

NoSQL databases are a great fit for many modern applications such as mobile, web, and gaming that require flexible, scalable, high-performance, and highly functional databases to provide great user experiences. The flexible data model makes NoSQL databases ideal for semi-structured and unstructured data.

What is the best to use a NoSQL database?

The structure of many different forms of data is more easily handled and evolved with a NoSQL database. NoSQL databases are often better suited to storing and modeling structured, semi-structured, and unstructured data in one database.

Which NoSQL database is in demand?

MongoDB is a document store, and the current top NoSQL database engine in use today. As is the requirement for NoSQL engines, MongoDB does not use a relational schema, instead using JSON-like “documents” to store data.

What is the latency of a NoSQL database?

In our testing, a typical workload and configuration produced throughput that varied from 225 to 3200 operations per second between database products, while read operation latency varied by a factor of 5 and write latency by a factor of 4 (with the highest throughput product delivering the highest latency).
