SQL

SQL, or Structured Query Language, is the language used to work with databases. If you imagine a database as a big filing system, SQL is how you ask questions, make updates, or organize the information in it.

For example, you can use SQL to grab specific data (using a SELECT command), add new information (INSERT), or even update existing information (UPDATE). If you need to remove something, you can also use SQL to delete data (DELETE).

In short, SQL is a simple way to handle data, whether you’re working with small projects or large systems.

Aside from managing data, SQL helps you set up the structure of your database, like creating tables (kind of like spreadsheets) or changing them around. It’s useful in all kinds of databases, from small ones for personal use to huge systems used by companies. Even though there are different versions of SQL depending on the database you’re using (like MySQL or SQL Server), the core commands and ideas are pretty much the same.
