🔍 Understanding SQL and Databases

What is a Database?
A database is a structured collection of data that allows users to store, manage, and retrieve data efficiently. SQL (Structured Query Language) is used to interact with databases, making it a vital skill for anyone working with data.

📌 How to Create a Database in SQL

Creating a database in SQL is simple. You can use the following SQL command:

CREATE DATABASE my_database;

Once the database is created, we can start defining tables within it.

🛠 How to Create Tables in a Database

Tables store data in a structured format using rows and columns. Here’s how to create a table in SQL:

CREATE TABLE students (
id INT PRIMARY KEY,
name VARCHAR(50),
age INT,
email VARCHAR(100)
);

Each column in the table represents a specific attribute of the data, like ID, Name, Age, and Email.

✍️ How to Insert Data into a Table

To add data to our newly created table, we use the INSERT INTO statement:

INSERT INTO students (id, name, age, email)

This statement adds a new row into the students table with values for each column.

💡 Best Practices for Managing SQL Databases

✅ Use meaningful table and column names
✅ Choose the right data types for efficient storage
✅ Use primary keys to ensure data integrity
✅ Normalize your database to avoid redundancy
✅ Backup your database regularly to prevent data loss
