What are the fundamental SQL commands?

SQL (Structured Query Language) is a programming language used to manage and manipulate relational databases. The fundamental SQL commands include SELECT, INSERT, UPDATE, DELETE, and JOIN. SELECT is used to retrieve data from a database, while INSERT is used to insert new data into a table. UPDATE is used to modify existing data in a table, while DELETE is used to delete data from a table. JOIN is used to combine or merge data from two or more tables in a database. Understanding these basic commands is essential for working with SQL and relational databases.
