Databases and SQL

A simple guide to how websites store, search, and manage information.

Final Project Overview

This website explains what databases are, why they matter, and how SQL helps people retrieve and manage information. Databases support many websites and apps by storing records such as users, products, orders, grades, and messages.

SQL stands for Structured Query Language. It gives users a clear way to ask a database for information, add new information, change existing information, and remove information when needed.

What Is a Database?

A database is an organized collection of data. Instead of storing information randomly, a database keeps data in tables, rows, and columns so a computer program can find and update records quickly.

Why SQL Matters

SQL helps websites and applications work with data. A store website uses SQL to find products, add orders, update accounts, and remove old records. A school system uses SQL to manage courses, grades, and student information.

What I Demonstrated

This final project demonstrates HTML structure, CSS formatting, images, navigation links, multiple pages, and JavaScript. I used header, nav, main, and footer sections to create a complete website layout.
