NoSQL databases were developed for use cases where a traditional relational database is not sufficient due to the size (volume), type (variety) or speed (velocity) of big data. Some NoSQL database models also allow developers to store serialized objects into the database, not only simple string values. They are designed to handle a great variety of data, including data whose structure changes over time and whose interrelationships aren’t yet known. Users should select the database based on their product needs. According to the website stackshare.io, more than 3400 companies are using MongoDB in their tech stack.

Instead of joining tables of normalized data, NoSQL stores unstructured or semi-structured data, often in key-value pairs or JSON documents. These types of databases are optimized specifically for applications that require large data volume, low latency, and flexible data models, which are achieved by relaxing some of the data consistency restrictions of other databases. Thus NoSQL can ultimately become larger and more powerful, making these databases the preferred choice for large or ever-changing data sets. While both are viable options, there are 11 key differences between them that you must keep in mind when deciding. These NoSQL databases do not require tables with a fixed set of columns, avoid JOINs and typically support horizontal scaling. Other NoSQL-related storage solutions, e.g. This tutorial uses straightforward examples to highlight basic NoSQL concepts, features, and types. What You Should Know About NoSQL Databases. NoSQL databases are distributed, non-relational, open source and are horizontally scalable (in linear way). NoSQL databases overcome this disadvantage. NoSQL databases are the ones that don't use SQL commands for querying. Object- or XML-databases, are called “soft-NoSQL” systems. NoSQL databases provide a viable solution by focusing on performance and availability while also sacrificing some of the consistency usually identified with relational databases. E.
