Hello guys, if you are on the fence whether to learn SQL or not, or want to learn SQL but not sure whether learning SQL is worth your time and effort then you have come to the right place. Earlier, I have shared best SQL books and courses to learn SQL for Beginners and in this article, I am going to share 10 Reasons to learn SQL. From my 18 years of experience as Software developer and 12 years as a blogger I can safely say that you should learn SQL. In all of these times, I have constantly worked with SQL in my projects and job. While database changes form Oracle to MySQL, to SQL Server, and now PostgreSQL but the knowledge of SQL still pays off.
SQL is also one of the most in-demand skill for Software developer job and having SQL keyword in Resume makes a huge difference in getting calls and job offers. In short, if you are not sure, learn SQL, if you are in doubt, learn SQL, you will not regret it.
The database is an important part of modern development. Working with a database is not easy and becomes tougher if the technology or language being used is complicated. If you have any experience in backend development, you may encounter the term "SQL". SQL stands for Structural Query language. It is used to manage relational databases.
A traditional relational database has tables with rows and columns. SQL is used to create such databases and manage them. With SQL, we can add, access, update, and delete data by writing queries. These queries are declarative statements that consist of several clauses. SQL queries can be very simple and at the same time, they can be so complex that even experienced developers will get confused.
SQL has a long history. It first appeared in 1974, nearly 50 years ago. At that time, development standards were nothing compared to modern development. More and more languages and technologies have come out since then. But SQL still maintained its position. Even with the emergence of NoSQL databases such as MongoDB, SQL popularity was affected little.
But many developers, especially beginners have doubts whether they should learn SQL in 2023. Of course, one can argue that learning other popular database technologies such as MongoDB is a better option but that does not mean that SQL is dead. In this article, we will list the top ten reasons for learning SQL in 2023.
4. Managing data
Data pools can vary in size. It is fairly easier to manage small-sized and medium-sized data pools but when the data pool size increases, it is tough to manage it. SQL is perfect to handle such large-sized data pools. It does not matter if the size is 100 or 100 million, SQL can handle it efficiently.
5. Servers
Along with databases, servers are also a very important part of the backend. SQL is also useful when it comes to servers. MySQL is one of the most popular tools used to create and manage servers. There are several other SQL-based tools for dealing with servers. So if you know SQL, you can work with databases as well as servers.
6. Data mining
CRUD operations are common when working with databases. If you want to become a professional backend developer, you need to understand CRUD operations and how to perform them efficiently. SQL queries perform CRUD operations very efficiently. If you understand the basic clauses of SQL, then you will definitely understand how CRUD operations work.
7. Working with multiple sources
It is not necessary that there is only one source of data in an application. There can be multiple sources and in modern development, it is common to have more than one source. You may encounter a situation where you have to combine data coming from multiple sources. This can be tough and time-consuming. In SQL, it is quite easy to combine data from multiple sources. You only need to understand the UNION operation.
8. Programmer friendly
Now, every programmer who is reading this article will agree that it is always best to work with that language or technology that is programmer-friendly. SQL is a very user-friendly programming language. Its syntax is easy to understand and troubleshooting is quite easy. For example, if there is a syntax error, SQL will clearly mention where it is. Moreover, the error message is clear and up to the point.
9. SQL knowledge is always plus
So it is not necessary that only data engineers or database administrators should have SQL knowledge. As mentioned earlier, SQL is nearly 50 years old and it is everywhere. Almost every company that has databases often wishes for someone fluent in SQL.
