NoSQL – A Comprehensive Guide for Beginners

NoSQL databases or Non SQL are very versatile and scalable database management systems that make it feasible to store and analyze unstructured as well as semi-structured data, something that is not achievable with RDBMS technologies. In this article, we explain what is Non SQL that covers everything from scratch useful for the understanding of beginners. Join Softlogic Systems for the Best NoSQL Course in Chennai.

Why NoSQL?

With a CAGR of 35.1%, the worldwide Non SQL market is anticipated to reach $3.4 billion by 2020.

Massive volumes of data are being produced throughout the world due to the digital age. The majority of conventional databases are not designed to manage various types of data with ease, necessitating the development of databases that do not require the modeling and structuring of data structures prior to storage.

This issue with relational database management systems was addressed by Non SQL (Not Only SQL), which allowed businesses to store enormous volumes of structured, semi-structured, and unstructured data in realtime. It doesn’t necessarily mean that it limits how SQL may be used with these databases. HBase, Cassandra, IBM Informix, MongoDB, Amazon SimpleDB, and other well-known NoSQL databases are only a few examples. Today, the majority of the world’s most well-known companies, like Google, Facebook, Amazon, and others, use NoSQL to deliver cloud-based services in realtime.

What was the challenge in traditional databases and how NoSQL is fixing it?

We need to distinguish relational databases with No-SQL databases to better understand what No-SQL is:

What was the challenge in traditional databases and how NoSQL is fixing it?
FactorsTraditional RDBMSNoSQL
Data ModelTables and SchemasPartition Key for data access
ACID PropertiesStrictly followedFlexible
Data ManipulationQueries will be used in SQL and executed by RDBMSObject-based APIs
Data VelocityModerateLarge
Suitable forStructured DataStructured, Semi-structured, and Unstructured


  • Due to the lack of schema creation and statically defined data structures, Non SQL is agile.
  • It employs objects, collections, and nested collections in place of tables.
  • Deployed across several inexpensive Intel-based servers
  • With the aid of data replication that is both uni- and bi-directional and equipped with big data, cloud, mobile, and web technologies, instant failover is possible.
  • Trades its traditional ACID characteristics for more flexibility and agility.

Since relational databases were created many years ago, before the internet, and were intended to be put on a single large server, digitization. However, with the development of the internet and the digital economy, this technology was unable to meet the dynamic needs, and Non SQL systems gained popularity.

When relational databases were first utilized by the applications, the developers had trouble matching the data structures that each platform supported. To move data to and from the database, they had to transform the in-memory data structures into relational ones. This significantly decreased the systems’ agility and performance.

NoSQL databases: what are they?

NoSQL databases, on the other hand, address this problem by integrating a wide range of technologies that make the systems scalable and appropriate for large data operations. This is accomplished by dividing the workload across numerous inexpensive servers with Intel architecture, enabling the platforms for real-time processing.

Although these two coexist on many platforms, more and more businesses are choosing to use NoSQL databases to handle large data operations.

How to Set Up a NoSQL Database

There are four main ways it may be used:

Columnar databases: Read and write data in columns as opposed to rows. In RDBMS, where a Key identifies a row and a single row might have numerous columns, each column is equivalent to a container.

Document databases: These databases are used to store and retrieve semi-structured data that is presented as documents in formats like XML, JSON, etc. Many well-known document databases, like MongoDB, include a robust query language enabling easy access and seamless switching between data formats.

Graph databases: These databases store data as relationships between entities, which speeds up traversal and joining processes. However, both SQL and Non SQL databases may be used to create these graphs.

In-Memory Key-Value Stores:  These databases keep crucial data in memory, which enhances system speed and is suitable for read-heavy workloads and compute-intensive workloads.

How Does Mastering NoSQL Enhance Your Career?

Everyday changes in technology necessitate that individuals get a solid understanding of them. NoSQL databases, a new development, have sparked a demand for database administration specialists among businesses. When used in conjunction with Hadoop, its growth trajectory is steadily accelerating.

The average compensation of Non SQL software engineers, developers, and programmers is over 1,000,000 Rupees, making it a popular and challenging work at present, according to the well-known employment and research organization Additionally, even newcomers and experts with one year of experience receive 650,000 rupees.

MongoDB, Cassandra, HBase, CouchDB, Redis, and other well-known databases are some of the ones that are now in style. Because it offers important services to businesses, it has acquired a lot of traction over the past few years. The necessity for these databases is seen to be increasing daily, especially now that it has found a home in the big data world.

Who Should Obtain NoSQL Database Training?

There are plenty of well-paying job possibilities that need knowledge of these databases. However, the following are some of the particular profiles for whom mastering these technologies will open up new job prospects:


The need for database specialists has increased significantly as businesses get ready to use alternative database systems that deliver better and error-free performance on big data platforms. Since the era of relational databases has long since passed, Non SQL technologies are becoming increasingly popular, offering tremendous employment chances to those who wish to succeed in this field. Therefore, learning it is crucial if you want to advance your profession to a new level. Develop your skills in our NoSQL Training in Chennai with IBM Certification at Softlogic Systems.
