What is SQL?

SQL or structured query language, was developed by IBM scientists Mr Donald Chamberlin & Raymond Boyce in the 1970s.

Users can query, delete, insert and update records in a relational database using SQL.

SQL facilitates complex logic application via transactions and embedded procedures.

The database most commonly for SQL is Microsoft SQL Server, which is owned & maintained by Microsoft.

What are the various types of SQL databases?

Fig 3: A graphical representation of the various SQL types.

There are four types of SQL databases, and they are as follows:

MySQL

MySQL is the most popular SQL database which has been acquired by Oracle.

PostgreSQL

PostgreSQL is one of the advanced types of SQL data that is a step up from MySQL.

SQLite

SQLite is used because of its library, which is identical to C.

Microsoft SQL Server

Microsoft SQL Server, or MSSQL, is also one of the popular Database Management Systems (DBMS) that helps in rendering innovative IT solutions.

What are the Key Features of SQL?

Here are the key features of SQL,

Data Definition Language (DDL)

SQL is a DDL; i.e., specific commands can be used to define and modify the database’s structure.

Data Manipulation Language (DML)

Using a set of commands, an SQL database can be manipulated accordingly.

Query Language

SQL also provides commands to query the database and get, filter, group, sort & join data.

Transaction Control

It supports transaction processing, allowing its users to club a set of operations into a single transaction.

Data Integrity

SQL can ensure data integrity by maintaining the quality of entries in the database.

User Access Control

Via SQL, users can be given usage-based control by limiting their access.

Portability

An SQL code can be used in various database management systems with minimal modifications.

What are the Use Cases of SQL?

If you wish to know how SQL can be used in 2025, here are some examples.

–        Data Alteration (within a table)

–        Table Creation

–        Data Retrieval

–        Data Manipulation

–        User Access Control

Now, you know good enough about SQL.

What is NoSQL?

NoSQL, or Not only SQL, was invented by Mr Carlo Strozzi in 1998 and is not owned by anyone.

Rather, various database companies like Apache Cassandra, MongoDB, Oracle NoSQL and more have their versions.

NoSQL is completely opposite of SQL, as it is not relational in nature.

NoSQL systems are much more flexible than conventional databases, which is the need of the hour.

What are the Main Types of NoSQL databases?

Fig 4: A graphical representation of the various NoSQL types.

There are, namely, 5 types of NoSQL databases, and they are as follows:

Key-value Database

It stores data in the form of key-value pairs by keeping the association of these keys simple and with one unique value.

Document Database

Via a document database, one can easily store documents in formats like XML, BSON, JSON and more.

Tabular Database

Also known as wide-column stores, it helps in using and storing data tables while keeping rows & columns free (not fixed).

Graph Database

It helps in storing data in the form of edges and nodes (not as tables), which is needed for apps using relational databases.

It comes in handy in social networking, recommendation engines, fraud detection and more.

Multi-model Database

It allows multiple data model implementations and thus enriches the stored data via tables, graphs, key values & more.

What are the Key Features of NoSQL?

Below mentioned are the key features of NoSQL,

Multiple Data Model Compatibility

NoSQL is compatible with multiple data models, making it quite flexible, be it for structured data, unstructured data or semi-structured data.

Boosted Availability and Scalability

NoSQL delivers a peer-to-peer architecture that is serverless and consistent amongst all nodes.

Thus, allowing for the scalability needed to develop cloud-native applications.

Global Data Distribution

Using NoSQL, databases can distribute data all across the globe via multiple clouds and data centers.

Almost Zero Downtime

NoSQL offers almost zero downtime via serverless architecture and multiple copies across the world.

What are the Use Cases of NoSQL?

Here are some of the top use cases of NoSQL,

–        Big Data

–        IoT (Internet of Things)

–        eCommerce

–        Content Management

–        Mobile Applications

Are you ready for the comparison now?

SQL vs NoSQL: The Key Differences

It is time to finally put these two database management technologies head-to-head to understand which is better for you.

Attributes	SQL	NoSQL
Data Structure	It uses a data structure that is based on the relational model.	It does not require a normalized data configuration.
Language	SQL languages – Pure SQL and enhanced versions like T-SQL (Transact-SQL) or more	Language depends upon the type of NoSQL database used.
Schemas	A predefined schema is needed.	Dynamic schema used
Data Integrity	Higher data integrity	Lower data integrity compared to SQL
Scalability	SQL databases can scale vertically.	NoSQL databases scale horizontally.
Querying	Efficient query processing	Query processing is complex.
Maturity & Support	Built on mature tech and have great support	Built on less mature tech and has less support
Consistency	Strong Consistency	Consistency varies
Joins	Complex joins supported	No or little support for Joins
ACID (Atomicity, Consistency, Isolation and Durability) Followed	ACID is followed for transaction management.	Not followed
Typical Apps	CRM, ERP, Financial Systems	IoT, Content Management, Social Networks

Shall we dive a little deeper into these differences?

SQL vs NoSQL: Database Architecture

Database architecture paves the way that a database uses to store and process data.

–        SQL uses relational databases and stores data in rows & tables.

–        NoSQL uses non-relational databases, and it stores data depending upon the type of data stored.

Result

Choose NoSQL if you have multiple data types and SQL for a singular data type.

SQL vs NoSQL: Database Scaling

The scaling method helps in understanding how a particular database will correspond to future requirements.

–        SQL scales vertically, or in other words, you can simply add more processing power (CPUs, SSDs or more).

–        NoSQL scales horizontally, or in other words, via sharding, which means adding new servers.

Result

Choose NoSQL if you wish to store videos & images and SQL for the rest.

SQL vs NoSQL: Language

The language helps in aligning your current developmental know-how with the database that will be easier to work with.

–        SQL databases use either SQL or modified SQLs like T-SQL.

–        NoSQL databases can use JSON or JavaScript Object Notation, binary schema, YAML (Yet Another Markup Language or YAML ain’t markup language), and XML (Extensible Markup Language).

Result

Choose NoSQL if you don’t wish to be restricted in the languages.

SQL vs NoSQL: Support

Without proper support, the future updates and issues might not be efficiently handled.

–        SQL is supported on diverse database systems.

–        NoSQL can have varying support on different database systems.

Result

Choose SQL if you need full support.

With the above information, it is clear that SQL should be chosen for reliability, while NoSQL should be chosen for its diversity.

SQL vs NoSQL: When to Choose Which One?

If you need further clarification, we’ve got you.

You should,

Choose SQL Databases

When,

–        Using highly structured data that does not change often

–        You are building a transaction-dependent system like banking.

–        High data integrity is needed.

–        You are bound to undertake complex queries.

–        Your business needs vertical scaling.

Choose NoSQL Databases

When,

–        Your business works on semi-structured or unstructured data.

–        You need a dynamic schema or have varied data types.

–        Horizontal scaling (even across the globe) is needed.

–        Streamlining development and decreasing the budget are your key development goals.

–        Lower data integrity is fine.

We are sure that now every business and developer can choose one out of SQL vs NoSQL to deliver the future-ready databases.

Conclusion

As we all know, databases are the backbone of any digital solution, so we need to pay attention to it in the initial phase.
