What is SQL?
SQL (Structured Query Language) is the standard language used to communicate with relational databases. It allows users to create, read, update, and delete data stored in a structured format.
- Declarative: You describe what you want, not how to do it.
- Standardized: SQL is supported by most relational databases like MySQL, PostgreSQL, SQLite, and more.
- Versatile: Used for querying data, defining schemas, managing permissions, etc.
Example SQL query:
SELECT name, age FROM users WHERE age > 18;
