SELECT department_id, SUM(salary) AS total_salary FROM employees GROUP BY department_id;
Explanation:
GROUP BY department_id: This groups all rows in the employees table by their department.
SUM(salary): This calculates the total salary for each department.
The result will show the department_id along with the corresponding total salary.
Why use GROUP BY?
It allows you to analyze data at different levels of granularity (e.g., department, region) by summarizing data in a meaningful way.

Hope it helps :)SELECT * FROM employees INNER JOIN departments ON employees.department_id = departments.department_id;
This will only return rows where an employee has a department.
LEFT JOIN: It returns all the rows from the left table, along with matching rows from the right table. If there is no match, NULL values will be returned for the right table.
Example:
SELECT * FROM employees LEFT JOIN departments ON employees.department_id = departments.department_id;
This will return all employees, even if they don't belong to any department (NULL will be returned for department-related columns).import pandas as pd
df = pd.read_csv('sales_data.csv')
df.drop_duplicates(inplace=True) # Remove duplicate rows
df.fillna(0, inplace=True) # Fill missing values with 0
print(df.head())
💡 Tip: Always check for inconsistent spellings and incorrect date formats!
📌 Task 2: Analyzing Sales Trends
A company wants to know which months have the highest sales.
✅ Solution (Using SQL):
SELECT MONTH(SaleDate) AS Month, SUM(Quantity * Price) AS Total_Revenue
FROM Sales
GROUP BY MONTH(SaleDate)
ORDER BY Total_Revenue DESC;
💡 Tip: Try adding YEAR(SaleDate) to compare yearly trends!
📌 Task 3: Creating a Business Dashboard
Your manager asks you to create a dashboard showing revenue by region, top-selling products, and monthly growth.
✅ Solution (Using Power BI / Tableau):
👉 Add KPI Cards to show total sales & profit
👉 Use a Line Chart for monthly trends
👉 Create a Bar Chart for top-selling products
👉 Use Filters/Slicers for better interactivity
💡 Tip: Keep your dashboards clean, interactive, and easy to interpret!

✅ NumPy – Used for handling numerical data and performing complex calculations. It provides support for multi-dimensional arrays and efficient mathematical operations.
📌 Example: Creating an array and performing basic operations:
import numpy as np arr = np.array([10, 20, 30]) print(arr.mean()) # Calculates the average
✅ Matplotlib & Seaborn – These are used for creating visualizations like line graphs, bar charts, and scatter plots to understand trends and patterns in data.
📌 Example: Creating a basic bar chart:
import matplotlib.pyplot as plt plt.bar(['A', 'B', 'C'], [5, 7, 3]) plt.show()
✅ Scikit-Learn – A must-learn library if you want to apply machine learning techniques like regression, classification, and clustering on your dataset.
✅ OpenPyXL – Helps in automating Excel reports using Python by reading, writing, and modifying Excel files.
💡 Challenge for You!
Try writing a Python script that:
1️⃣ Reads a CSV file
2️⃣ Cleans missing data
3️⃣ Creates a simple visualization
