5 Reasons Why You Should Learn SQL in 2023

 

SQL is pronounced "sequel" by some and "S-Q-L" by others. SQL stands for Structured Query Language, a standard and widely accepted language used for database maintenance by performing operations such as data retrieval and manipulation. SQL has been around since the 1970s. Now the question is, what has kept SQL relevant for so long in this technological age that is constantly dynamic and evolving? With this, a follow-up question arises: Will the demand for and significance of SQL continue in 2022? Both of these questions will be addressed in this article.

SQL is more than just a programming language; it also allows us to work with data by viewing it as logical sets, similar to how joins in SQL adhere to the Venn diagram concept. It is correctly referred to as a programming language that incorporates set theory concepts.

1. A Programming Language That Isn't Just For Programming Tasks

Yes, you read that correctly!

Typically, programming languages are assumed to be used only for programming purposes, but SQL defies this stereotype by allowing people in the marketing or sales team to look through their data by running a few queries on the dataset, such as to see the trend of their sales or marketing campaigns. SQL is also useful in the finance sector because it is useful for financial analysis, which saves a lot of time when going through large amounts of finance data.

2. SQL or a variant of it is supported by almost every data technology

Technology is constantly evolving. To survive in the tech industry, one must always be up to date on the latest technologies. Because most data-oriented technologies use SQL interface, SQL becomes a friend during the learning process. Because all aspects of technology contain data, they must all support SQL in some form or another. However, learning SQL is a win-win situation because it is likely to come in handy while working on any data or data-driven technology.

3. Beneficial in Handling Massive Amounts of Structured Data

Can you figure out what the most valuable thing in the technological era is? It's not money, gold, or a diamond.

It's information! This valuable data must be efficiently stored and managed. Because of the COVID-19 outbreak, many industries will be completely virtual by 2022. More books are being replaced by ebooks, more papers are being replaced by pdfs, and more data entry registers are being replaced by excel sheets. This leads to more data, which leads to the need for data management. When you have a database with millions of entries, manually analysing data is not always convenient. SQL queries make it possible to perform a variety of operations, such as retrieving rows from a large database based on specific filter criteria and manipulating them as needed.

4. A Beneficial Data Analytics Tool

Data analysis entails the processing and interpretation of data in order to extract valuable information that can be used to answer a question or solve a problem. SQL is the most in-demand skill in the skill set for Data Analyst roles because data analysis involves working with massive amounts of data and manipulating it. By analysing business trends, SQL makes it easier for a data analyst to make strategic business decisions that benefit stakeholders.

5. The Cherry on a Cake For Data Mining

"Data Mining is the process of discovering new patterns from large data sets," says the cherry on top. -Wikipedia

SQL, as we know, works with data, so when large data sets are involved, SQL can assist in mining useful data from a pool of datasets.
