Hello folks, SQL is one of the most important skills in today’s increasingly data-driven world. It’s not just important for any programmer like a Java, C++, Python, JavaScript, or Ruby developer but also for people who are learning Data Science and Data analysis.
You may not believe it, but in my 20 years as a Java developer, I found that almost 95% of Java applications use a relational database in their back-end and almost all web applications use the database.
In recent years, one of the most common ways to learn any programming skill is learning online, in the comfort of your office or home, and SQL is no different. Learning SQL online has another advantage of a quick head start because you don’t need to install a database and create tables to write some SELECT queries.
