Advantage of NoSQL over SQL

NoSQL is an emerging term for a database that is becoming more popular among developers. NoSQL refers to the Non-Relational Database, which stands for “Non-SQL,” and sometimes it is called “Not only Structured Query Language.” SQL is a structured query language that is generally used for Different database management systems. This term NoSQL doesn’t require any query language. Further in this article, we are going to clarify the advantage of NoSQL over SQL.

Before elaborating on the advantage of NoSQL over SQL, we need to understand the main definitions. The first one is Relational Database (SQL) and the second one is a Not Relational (NoSQL) Database. Both have their specified features but we will focus on the main advantage of NoSQL over SQL.

SQL Database (Relational)

Structured Query Language is referred to as SQL. It is a set of organized tables, and a table is a group of records or rows, which is also referred to as a table’s attribute. Relational database management systems use the SQL programming language to perform basic database operations as needed and compare the data to predetermined criteria. Numerous well-known databases, including MS SQL Server, MS Access, and Oracle, support the SQL engine. Additionally, open source databases like Maria DB, MySQL, and PostgreSQL are supported.

In other words, the data that SQL databases contain in tables are displayed to us in a simple, clear, and straightforward manner. Each row in those tables will represent a record with a distinct identifier (known as a key). Columns will include those keys’ properties, typically with unique values (which allows us to create those relationships between the data of the entire database).

NoSQL Database (Non-Relational)

In contrast to traditional databases, a NoSQL database offers a flexible structure and numerous ways to store data. This implies that information not presented in a tabular format can be stored and retrieved. The purpose of doing so is to address the scalability issue with relational databases, encourage simple design, and provide the database with the capability of horizontal scaling. Document databases, graph databases, wide-column stores, and key-value databases are the four main types of NoSQL databases that have developed throughout time.

This type of data storage, in contrast to the preceding ones, does not employ such basic structures (tables), nor is its data kept in the form of records or fields. That does not imply that they do not use SQL. Its term itself, as we previously discussed, actually implies utilizing SQL occasionally rather than never. They rely on it, but only as a backup method rather than as their main search engine.

Following are the advantage of NoSQL over SQL

i.            Sizable Data

The current trend in transaction rates has resulted in a massive increase in the amount of data being saved. To keep up with this expansion, RDBMS capacity is rising dramatically, but for certain businesses, managing the volume of data with a single RDBMS is becoming unfeasible. NoSQL systems assist to manage massive volumes of data, such as Hadoop, beyond that which can be fixed by only the largest RDBMS, therefore they may overcome this problem.

ii.            Get rid of DBA’s

Only the assistance of highly skilled, expensive DBAs may be used to administer RDBMS systems. RDBMS systems are installed, designed, and continually tuned by DBAs. Automatic repair, data distribution, and less management are needed for NoSQL databases, whereas automatic repair, tuning, and maintenance are not as necessary.

iii.            Better Elastic Scaling than RDBMS

A scale-up is something that the database administrators always rely on. Invest in larger servers because the database won’t scale out but rather increase the load. On commodity clusters, the RDBMS will be difficult to scale out. The fact that the new breed of NoSQL databases is built to expand transparently to benefit from more nodes, which dramatically lowers the cost of commodity hardware, is one of their key advantages.

iv.            Cost efficient (Least Cost than RDBMS)

RDBMS relies on expensive storage and exclusive server platforms. While NoSQL databases frequently use groups of inexpensive commodity servers to manage the enormous transaction and data volumes. NoSQL is, therefore, more affordable than RDBMS and enables processing and storing more data at a significantly lower cost.

v.            Simple and user Friendly:

NoSQL databases have mostly been used by developers because they find it simpler to build different types of apps utilizing them than with relational databases.

JSON is used by document databases like MongoDB to transform the data into something far more like code. This enables the developer to have control over the data’s structure.

Fewer transformations are needed when transferring data into and out of NoSQL databases since they store data in forms that are similar to the kinds of data objects utilized in applications. Developers don’t need to modify the data to fit the store because NoSQL databases could store information in native formats. Storing data “as is” eliminates the need for a front-end ETL system to convert semi-structured data into column and row formats and reduces the number of apps that need to be created or acquired to launch a new database. There is a sizable development community that surrounds the majority of NoSQL databases. This implies that there is a tool ecosystem and community of other developers to connect with.

vi.            Zero Downtime Delivery of the Cloud

The scale-out architecture used by the majority of NoSQL databases not only offers a direct path for scaling to support massive data sets and large traffic levels. Using a group of computers to deliver a database also enables the database to dynamically increase and decrease its capacity.

Additionally, many NoSQL databases allow for upgrades and the ability to update the database’s structure with no downtime. Following further defining the advantage of NoSQL over SQL in the context of MongoDB.

MongoDB continues to maintain its position as the database most desired by developers, according to StackOverflow, thanks to the popularity it enjoys among developers in general and JavaScript developers in particular.

MongoDB Atlas, the fully-managed version of MongoDB that runs on all the main public clouds, can be used to get started right away or to learn more about the special benefits of MongoDB.

vii.            Supports almost every type of Big Data

Support for unstructured databases is the main benefit of NoSQL databases. Relational databases keep data in an organized manner with a preset schema, and a suitable data model architecture needs to be in place before the data begins to enter the database. Once the data has been uploaded further into a database, you can use the SQL programming language to retrieve the data that has been saved there and send it to the associated application. The user’s data will be sent and returned by the program to the database.

NoSQL databases have adaptable schemas that are simple for programmers to manage. The new schema formats are simple to adapt. A native feature or an interconnected set of services can be used to manage the indexes in unstructured data. With the aid of unstructured data, many organizations are now able to acquire insights into their industries and make better decisions.

Furthermore, to answer the question of the advantage of NoSQL over SQL, you also need to know about Big Data and types of Big Data.

viii.            Big Data Management support

It supports Big Data, which includes vast and intricate data sets from both old and new sources. Such data sources have a volume that is too large for the conventional relational database management system to handle.

  • Structured Data:

This kind of data can be handled easily using a variety of terminologies and skills. because the formatting and sequencing of all the data are precisely handled. This makes it simpler for the tools to manage and extract the data. The fundamental issue is the data’s size or quantity, which is growing far too quickly.

Furthermore, any data that can be retrieved, processed, and stored in a set format is referred to as structured data.

  • Semi-Structured Data

Nearly all structured data is semi-structured. To transform this type of data into structured data, some fundamental terminology and operations were needed. because structured data can be extracted quickly and easily with the aid of tools. Semi-structured data includes both kinds of data. The semi-structured data in the database that contains the data without any specific relational processes is further elaborated on in the example that follows.

  • Unstructured Data

Any data that is undetermined in terms of shape or arrangement is considered unstructured. Handling unstructured data is extremely difficult and time-consuming. It creates numerous obstacles and prevents the use of data management technologies. Unstructured data is typically present in heterogeneous data sources, which include unstructured text files together with images, videos, and other types of data. Today’s organizations have access to a lot of data, but because it is unstructured or raw, they are unable to add value to it.

Unstructured Data Example

This is an example of a Google search page:

Further types of data support

  • JSON File Format

JSON files, a lightweight interchange format, are supported. It comprises key-pair values nested within data. It can effectively handle JSON files with very vast and complicated nested structures without impairing an application’s performance.

  • Database of Graphs

You can use it to navigate connections between the characteristics of various nodes.

  • Binary Information

The support for binary values, maps, lists, etc. is available.

  • Collapsed Data

You can save data into columns rather than rows with its assistance.

ix.            Computer Programming Languages

In relational database management systems, SQL is the most often used language for database operations. Utilizing its unique accessibility language to understand the sending and receiving of material within the database, NoSQL also offers the ability to write SQL queries, like in Business Analytics (Ba) tools. It enables developers to concentrate on what is needed for the application rather than first building the data model and then delving into the details of the database structure.

x.            Case scenario

Unstructured data types like documents or JSON are thought to work better with NoSQL databases. On the other hand, SQL databases are utilized to manage concurrent transactions in several table rows.

xi.            Scaling Horizontally

You may manage databases across multiple servers using NoSQL databases. If the amount of data is increasing faster than you anticipated, you may, for instance, add more cheap servers to your main database cluster. This addition is referred to as horizontal database scaling. However, relational databases may scale vertically without the need for more expensive, more powerful servers. The cluster becomes more robust and resilient in terms of infrastructure with the inclusion of inexpensive hardware upgrades, including servers and storage. NoSQL allows for hardware upgrades and the seamless integration of new clusters into a current system. 

xii.            ETL Reduced Requirement

It stands for Extract Transform and Load (ETL). The storage of “as is” data is made possible by NoSQL databases. The storage of condensed data structures is made easier by the key-value store. On the other hand, a variety of stacked or flat structures can be easily handled by document NoSQL databases.

Most data that moves across systems do so in the form of a message. The data often has one of three formats: a binary object designed to transit through multiple layers, an XML document, or a JSON document. The amount of code required to convert from the issues identified to the required storage format is decreased by the ability of a variety of NoSQL databases to support these formats natively.


In conclusion, there are the main advantage of NoSQL over SQL and these advantages show clearly that the future is NoSQL because it has a lot of advantages over SQL. And SQL is not old-fashioned as compared to the services of NoSQL. NoSQL has provided a lot of new features that attract developers, most of which are mentioned above.
