SQL’s significance in the IT industry India will have more than 1.48 million computer-based businesses by 2022. Due to the rapid advancement of technology, people are undertaking an increasing number of activities online. A lot of money was spent in 2021 to produce more IT goods and services. A lot of data is generated as more individuals utilise the internet. IT firms must manage all of this data, which is where specialised database software comes in.

Similar to a large digital box, a database management system allows for the storage and organisation of a lot of data. Microsoft SQL Server, Oracle, and MySQL are a few common ones. Most significant businesses employ this kind of software. Let’s discuss SQL, a highly common language utilised in these systems.

What is SQL?

SQL is a unique language used to query databases or issue commands. Despite being older, it is still widely used for working with databases. It has a wide range of capabilities and is simple to adapt to use with different databases.

What characteristics does it have?

  • SQL is used by more than 65.2% of websites, demonstrating its strength and value. Let’s examine some of its capabilities:

  • - Data Definition and Manipulation Language: SQL has the ability to both construct and modify the database’s internal organisation of data as well as modify the data itself.

  • - User access control: SQL can limit who can access or modify data in order to protect it.

  • - High Scalability and Portability: SQL can run on a variety of computer platforms and is simple for beginners to utilise.

  • - Transactional Support: SQL is capable of handling a large number of tasks and data records without being overworked.

  • - Compatible with a variety of businesses: SQL may expand and evolve as your company grows.

What function does SQL serve in the IT sector?

India made a lot of money in 2021 by selling goods to other nations. The IT industry contributes more than half of this money. What role does SQL play in this? Let’s investigate.

More than 50% of database systems are on the cloud, making cloud migration simpler and more affordable for IT professionals.

  • Standardisation: Because SQL is based on a widely accepted standard, using it is simpler.

  • - Simpler Data Management: More than 42% of businesses worldwide use SQL to store and manage their data.

  • - Manual Analysis: SQL aids in the process of manually examining data and locating crucial information.

  • - Increased Employment: SQL is simple for beginners, which has led to a large increase in employment in the IT sector.

  • - Relationship with other sectors: Data analysis is used by almost all businesses, not only those in the IT sector. Any business can manage this with the use of SQL.

Developers Benefits:

  • SQL enables the creation, modification, and extraction of data from databases, which is essential for many applications and websites.

  • - Learning Curve: When compared to other programming languages, SQL is simpler to understand and use. It has a simplified syntax that is easy to understand.

  • - It is a crucial tool for back-end development, assisting in the efficient management and organisation of data.

Added advantages for data scientists

  • Data handling and analysis: A common chore in data science, handling and analysing massive volumes of data is made a lot easier with SQL.

  • - Effective Querying: Data scientists may quickly filter, sort, and carry out intricate operations on the data using SQL.

  • - Job Opportunities: Since most businesses use relational databases based on SQL to store their data, data scientists who are familiar with SQL may find it easier to get work.

  • - Focus on Interpretation: SQL makes data retrieval easier, allowing data scientists to devote more time to understanding the information and drawing conclusions.


The IT industry relies heavily on SQL, which has a promising future. As a result of its versatility and ease of cloud migration, it is growing in popularity. Therefore, it is obvious that SQL will remain crucial to the IT industry for a very long time.
