What is NoSQL?
NoSQL originally stands for “Non-SQL” or “non-relational” and is sometimes called “Not only SQL”. It is a kind of database management system (DBMS) that stores and handles volumes of unstructured and semi-structured data.
Generally, a NoSQL database means non-relational, distributed, flexible, and scalable. Instead of relational databases that use tables with pre-defined schemas to store data, NoSQL uses flexible data models that can adapt to changes in data structures and are capable of scaling horizontally to handle growing amounts of data.
What is the difference between SQL and NoSQL?
- SQL databases are relational databases (RDBMS), and NoSQL is a non-relational or distributed database.
- In SQL, you need to use predefined schemas to determine the structure of your data, whereas, in NoSQL, there is a dynamic schema for unstructured data. You can store data in different ways, like document-oriented, column-oriented, graph-based, or a key-value store.
- SQL databases are vertically scalable, which means that you can increase the load on a single server. In contrast, NoSQL databases are horizontally scalable that can handle more traffic by sharding or adding more servers.
- SQL works with ACID properties (Atomicity, Consistency, Isolation, and Durability). On the other hand, the NoSQL database works on Brewers CAP theorem (Consistency, Availability, and Partition tolerance).
Benefits of using NoSQL
There are several advantages of using a NoSQL database, like:
Flexibility
It is designed to handle unstructured or semi-structured data, which means NoSQL databases can accommodate dynamic changes to the data model, and it becomes helpful in handling changing requirements.
Highly Scalable
NoSQL databases can be modified to the different scaling needs of your business.
It requires less structuring than SQL, so every item is self-contained and independent. Therefore, each object is kept on separate servers and need not be linked.
NoSQL’s scale-out architecture makes scalability achievable through spreading the storage of data and the work to process the data over a large cluster of computers. This architecture works well when the data volume or traffic grows.
High performance
It is optimized for specific data models and access patterns that enable higher performance than trying to accomplish similar functionality with relational databases.
Availability
NoSQL with the auto replication feature becomes highly available because data replicates itself to its previous consistent state in case of any failure.
Highly functional
It offers highly functional APIs and data types, which are built for each of their respective data models.
Less ongoing database maintenance
It doesn’t need the same level of ongoing database administration as compared to traditional relational databases because NoSQL databases can automatically partition and replicate information across nodes.
