Databases are the heart of data science. You can’t separate them from each other<\/em><\/strong> and one can’t learn data science without learning databases. <\/em><\/strong><\/p>\n\n\n\n

If you start learning databases, you will find that, there isn’t one but many databases that data scientist put their hands on. One such important database is NoSQL.<\/strong><\/p>\n\n\n\n

In this article, you will understand everything about NoSQL, from its definition to its types, its importance, and lastly the misconceptions around it. <\/p>\n\n\n\n

So, sit tight and enjoy your journey through this database!<\/p>\n\n\n\n

What is NoSQL?<\/strong><\/h2>\n\n\n\n
\"What<\/figure>\n\n\n\n

The first thing that you should understand is that NoSQL stands for “Not Only SQL<\/strong>” and not “No need for SQL”. This is a simple misconception that everyone thinks of when they first hear the term. <\/p>\n\n\n\n

It’s a broad category of database management systems<\/a><\/strong> that differ from traditional relational databases<\/strong> like MySQL, PostgreSQL, and Oracle. <\/p>\n\n\n\n

The primary distinction lies in how the NoSQL databases store and retrieve data. Instead of using fixed schemas and tables with rows and columns, these databases are designed to handle unstructured data<\/strong>, offering greater flexibility and scalability.<\/p>\n\n\n\n

That is why, in most cases, these databases are preferred over others. <\/p>\n\n\n\n

Why NoSQL? Why is it Popular?<\/strong><\/h2>\n\n\n\n
\"Why<\/figure>\n\n\n\n

When deciding on a database for your project, you might wonder why you should consider NoSQL over others. As we said there are numerous databases to look out for. This section will cover why this database is more popular than others.<\/p>\n\n\n\n

Before we move any further, it is mandatory that you know the basics of data science and databases. If not, consider enrolling for a professionally certified online Data Science Course<\/a><\/strong> offered by a recognized institution that teaches you the basics and strengthens your foundation. <\/p>\n\n\n\n

Let us now see why this database might be the right choice for you:<\/p>\n\n\n\n

1. Scalability: Growing with Your Needs<\/strong><\/h3>\n\n\n\n

Imagine your application is like a small shop that turns into a huge mall as more people start visiting. Relational databases (SQL)<\/a><\/strong> are like a shop that can expand only by adding more shelves inside. <\/p>\n\n\n\n

In contrast, NoSQL databases are like building new stores next to each other to accommodate more customers. This is called horizontal scaling.<\/em><\/strong><\/p>\n\n\n\n
