SQL stands for Structured Query Language. It is used to write commands that tell a database what to do. With SQL, you can create tables, insert data, read records, update data, and delete data.
What is MySQL (SQL vs MySQL)
MySQL is database software that stores data. It understands SQL commands and responds to them. Because MySQL is free and easy to use, many beginners choose it for learning. In addition, websites and small projects often use MySQL.
What is PostgreSQL
PostgreSQL is another database system that uses SQL. However, it offers more advanced features than MySQL. As a result, developers use PostgreSQL for complex queries and large applications where data accuracy matters.
