Top 10 Reasons for Learning SQL for data science 2023
While others say “S-Q-L,” some people pronounce SQL as “sequel.” The widely accepted standard language known as SQL is used for database administration and allows for operations like data retrieval and manipulation. Since the 1970s, SQL has existed. Now, the question is: Why, in this rapidly evolving and developing technological era, did SQL maintain its level of popularity for so long? The question of whether SQL will be crucial and in demand in 2022 is raised by this. Both of them will be addressed in this essay.
SQL is both a programming language and a tool for working with data by allowing us to see it as logical sets, just as joins in SQL follow the Venn diagram paradigm. It is true to say that it is a computer language that uses concepts from set theory
In 2023, when the majority of activities and sectors will be virtual and online, let’s go over some advantages of learning SQL. Let’s look at the benefits SQL can have for your skill set.

SQL or a version of it is supported by almost all data technologies.
The development of technology continues. One needs to always keep up with new technology if they want to survive in the tech industry. SQL is a useful tool while learning new technologies because the bulk of data-oriented technologies use SQL interface. Regardless of what they are, all technological features must in some manner support SQL because they all include data. Yet learning SQL is a good idea because it will almost surely come in handy when working with data or data-driven technology.
With the Ability to Handle Huge Amounts of Structured Data
Identify the most valuable thing in the modern era if you can. Donate: It’s not money, jewellery, or a diamond.
It is data! Effective management and storage of this crucial data are required. The COVID-19 epidemic will cause various industries to transition to a virtual economy by 2022. The number of books being replaced by ebooks, the number of documents being replaced by PDFs, and the number of excel sheets replacing data entry registers are all increasing. More data is produced as a result, increasing the need for data management. Analyzing the data manually is not always feasible when a database has millions of records. You can extract rows depending on a variety of criteria using SQL queries, for example.
An Effective Data Analyses Tool
The process of analysing and interpreting data in order to extract significant information that could help answer a question or solve a problem is known as data analysis. SQL is considered as the most in-demand skill in the skill set for employment as a data analyst because completing data analysis necessitates working with enormous amounts of data and performing manipulation on it.

Quick Data Access
Because we now know that SQL can manage enormous numbers of data, allow me to add that SQL has incredibly quick access to data. When needed, a user can quickly and simply acquire information. This enables SQL-based data organisation and storage. With such easy access to data, the business can run more effectively.
data manipulation
In order to examine, manage, and access that data, SQL is used, making it a good choice for data manipulation. It makes it simpler for consumers to test and play with with the data. Furthermore, dynamic data is kept in SQL. Therefore, you are free to manipulate the data at any time.
In addition, many data visualisation tools, such Tableau and Google Data Studio, are built on SQL. As a result, learning SQL will help you better grasp what happens when you build a report in any data visualisation tool. For instance, let’s say you want to link your SQL database to a data visualisation tool and you have some information in it. Next, you’ll see two choices: Create a custom query and connect as a table. If you decide to use a custom query in this case, you can move on and modify the data to suit your needs.
Combine Information from Several Sources
We frequently find ourselves wishing to merge data from many sources, yet doing so can take some effort. It is quite simple to mix data from several sources when using SQL. Utilizing UNION operations, where you must specify the fields or databases that must be joined, is how this is accomplished.
