SQL (Structured Query Language) is used to manage and retrieve data from relational databases.
INNER JOIN returns matching records from multiple tables.
SELECT *
FROM Customers
INNER JOIN Policies
ON Customers.Customer_ID =
Policies.Customer_ID;
| WHERE | HAVING |
|---|---|
| Filters rows | Filters grouped data |
| Executed before GROUP BY | Executed after GROUP BY |
SELECT
Customer_ID,
Policy_Value,
RANK() OVER(
ORDER BY Policy_Value DESC
) AS Policy_Rank
FROM Policies;
Window functions perform calculations across rows without grouping them.
CTE stands for:
Common Table Expression
Used to simplify complex SQL queries.
Python offers powerful libraries for:
Data Analysis
Machine Learning
Automation
Visualization
Popular libraries:
Pandas
NumPy
Scikit-Learn
Matplotlib
Seaborn
| List | Tuple |
|---|---|
| Mutable | Immutable |
| Uses [] | Uses () |
Pandas is used for:
Data Cleaning
Data Transformation
Data Analysis
Reporting
Average value.
Middle value in sorted data.
Most frequently occurring value.
Standard deviation measures how much data varies from the mean.
Correlation measures the relationship between two variables.
Values range between:
-1 and +1
A statistical method used to determine whether results are significant.
Important concepts:
Null Hypothesis
Alternative Hypothesis
P-Value
Confidence Interval
| Supervised Learning | Unsupervised Learning |
|---|---|
| Uses labeled data | Uses unlabeled data |
| Predicts outcomes | Finds hidden patterns |
Overfitting occurs when a model performs well on training data but poorly on unseen data.
Solutions include:
Cross Validation
Regularization
More Data
Cross Validation evaluates model performance using multiple subsets of data.
Popular method:
K-Fold Cross Validation
Feature Engineering involves creating or transforming variables to improve model performance.
Examples:

Fraud Detection
Probability measures the likelihood of an event occurring.
Values range from:
0 to 1
Data Analytics is the process of analyzing data to uncover insights and support business decisions.
What happened?
Why did it happen?
What will happen?
What should be done?
EDA involves exploring datasets to identify:
Patterns
