Did You Know?
SQL was developed at IBM in the 1970s and was originally called SEQUEL.
SQL (Structured Query Language) is the standard language used to communicate with relational databases. Whether you are performing data analysis, building a backend API, or managing user records, SQL is the bridge between your application and your data. Because queries often involve multiple nested joins and filters, they can quickly become a 'wall of text.' Formatting is essential to keep these queries manageable and to ensure that database logic is clear to everyone on the development team.
Best Practice
Always uppercase SQL keywords to clearly distinguish them from your table and column names.
