SQL is ubiquitous. Every company, small or big, uses SQL. How? We live in a digital age today, where data analytics spans every aspect of business. Data analytics is only made possible with massive databases holding the data and ability to efficiently record and extract the data from these databases. And going hand-in-hand with databases is SQL. SQL or structured Query Language is the language for interacting with databases. It allows one to create, manipulate and query data from the databases. So Digital means data; data means databases; and to access those databases, you need SQL. SQL is therefore used everywhere.
If you do a quick job search you will realize that more companies are looking for SQL skills than are looking for Python or R skills. There is no denying the importance of learning SQL in this age of big data and business intelligence. All the jobs that involve storing data require professionals with SQL knowledge. Once you’ve earned proficiency in SQL, you can work in data science, business intelligence (BI), database administration, or back-end web development.
SQL works with most of the popular relational database management systems like Oracle, MySQL, Microsoft SQL Server, MariaDB, PostgreSQL, and more. It is a must-have skill that is going to serve you longer than any other programming language.
Learning SQL is much easier than you might think, and the benefits far outweigh the time and cost investment. SQL increases your value and marketability within your organization and in the broader market. There are a plenty of online resources to learn SQL. So, whether you are a graduate seeking your first job, or a professional looking to transition to data analysis, or an experienced data practitioner, you are sure to find an online SQL course at your level of technical ability.
