Structured Query Language continues to be the standard programming language that has created, designed, and managed relational databases since the 1970s.

It differs from other programming languages whose focus and capability are building Apps, Web Development, and Software Development.

SQL is used for storage, retrieval, and data manipulation in databases.

It is common knowledge that most applications are created using popular languages such as Python and Ruby, but a very different configuration is required when it comes to database creation.

This different configuration is the SQL which is useful to Programmers who can do the following:

  • Adding, updating, and deleting rows of data
  • Modifying database tables and index structures
  • Generating tables and database project
  • Retrieving information from databases to enable transaction processing and analytics

What makes SQL so special is its unique markup and its ability to use tables to configure data in rows and columns, allowing SQL users to access, manipulate and analyze specific datasets easily.

SQL is a vital database tool for aspiring Programmers, Data Analysts, Data Scientists, and Data Engineers.

You can also learn SQL for data analysis, which is why most professionals in the data field want to learn to code SQL.

If you haven’t learned SQL, you don’t need to worry because various resources will enable you to learn SQL for free.
