Talking to Databases
SQL (Structured Query Language) is how we communicate with databases. Think of a database as a massive, organised filing cabinet. SQL is the language you use to ask questions: "Give me all customers from London" or "Show products under £50 sorted by price." SELECT retrieves data, FROM specifies the table, WHERE filters results. It's like Google for databases!
