Nowadays, data are gathered from a variety of sources, and information is of great value to organizations. However, with an increasing amount of data comes the need for databases that can store information for retrieval and analysis by trained specialists. Thus, proper data analysis is in high demand in our digital world.

Relational databases, which logically group information into chunks, are basically used to store and organize large amounts of data. Of course, if you’re looking to retrieve any kind of information from a database, you need to speak its language! The most widely used language for interacting with databases is SQL (Structured Query Language), the gold standard of relational databases. SQL queries, which are essentially requests or instructions that you send to a database, allow you to retrieve information and update, insert, or delete data.

SQL is mainly associated with the IT sector and is an everyday tool for database administrators. Developers use SQL to write applications that require database connections, and systems architects use it to design database models. All of this means that learning SQL is a great choice for anyone who would like to pursue a career in IT.

However, if you’re not into all those zeros and ones, rest assured—IT specialists are not the only ones who benefit from SQL. It is, in fact, essential for any professional working with lots of data, such as a data analyst or scientist, and it’s a common tool in the fields of finance, banking, and marketing. When you know SQL, you can easily retrieve and process data you need without any assistance from an IT expert. You can also create reports and analyses more quickly and efficiently!

Now, we know what you’re thinking—what’s in it for me? Well, employees with SQL skills tend to earn more. Nowadays, many organizations are seeking specialists with SQL knowledge because retrieving and analyzing data is incredibly important for staying ahead of the competition and fine-tuning your business strategy. Thus, a specialist with SQL skills has a greater chance of earning a higher salary and working a better job.
