🌟 SQL: A Fun Dive into Databases 🌟

🤔 What's SQL and Why Should You Care?

Ever worked with a spreadsheet? Rows, columns, and all those cells filled with data. SQL is like a language that lets you talk to these spreadsheets. But instead of spreadsheets, we call them "databases" in the computer world.

🔍 Databases, Tables, Rows, and Columns

Imagine a giant Excel workbook:

• Tables: These are like individual sheets or tabs in our workbook. Each table has data about one specific thing, like a list of movies or a list of actors.

• Rows: Think of rows as individual entries on that sheet. Like one row for the movie "Jurassic Park" and another for "Titanic."

• Columns: These define the fields we're storing. For our movies, columns might be Title, Release Year, Director, and so on.

🔑 Key Takeaways:

1. SQL is a Language for Databases: Just as you use Excel to interact with spreadsheets, you use SQL to communicate with databases.
2. Tables in databases are like individual sheets in Excel.
3. Each table in a database is designed to hold information about one topic, like movies or actors.
4. Rows represent individual entries
5. Columns define fields that represent the different attributes of each entry
