NoSQLs work like a file where all data is stored, they allow you to work with a huge amount of information and organize it so that users can access it anytime they need it. Currently, there are different types of NoSQL, each of them works differently, most are written in C++. We can say that NoSQL databases center their functions on the basis of:
- Horizontal scalability with the ability to increase its size, increase the storage space in the database without compromising performance.
- Cloud technology. Most NoSQL databases base their storage in the cloud to free up more space. Besides, they have nodes for information replication.
- Efficient use of resources. Companies are currently in the process of technological transition, so it is almost necessary that they have a database that allows them to implement new technological tools. NoSQL data works for this very purpose – a flexible model allows you to quickly adapt to new tools.
- A free scheme of functioning. NoSQLs do not have a rigid system, so programmers have the freedom to change data as needed. This means that if you need to change the definition of a field or data type, it is no problem, unlike SQL databases, where such changes are associated with great difficulties.
- Response speed. The speed in the database is measured by latency, which is the response time, NoSQL is concerned with minimizing the latency as much as possible.
- Use of indexes. SQL and NoSQL both need indexes because queries can be made across millions of records if an index has not been configured. In NoSQL, indexes are created in the form of a B-Tree, which means that the nodes are balanced, which means that the search speed increases.
