NoSQL databases offer several advantages over SQL, some of which are as follows:
- Flexibility: NoSQL databases can access and store various data structures within a database, which also includes unstructured data. This makes it easy to alter data fields. NoSQL also allows you to add attributes and fields.
- Scalability: By adding servers, NoSQL databases can scale horizontally making them suitable for large quantities of data and applications with a lot of traffic. On the other hand, SQL databases scale usually on a singular server vertically and hence can only increase storage with the help of more physical hardware.
- Performance: NoSQL databases can write or read data faster compared to SQL because they store data together. They can alter the database structure and upgrade without downtime.
