4) where
5) group by
6) having
7) limit
8) Joins (Left, right , inner, self, cross)
9) Aggregate function ( Sum, Max, Min , Avg)
9) windows function ( row num, rank, dense rank, lead, lag, Sum () over)

11) Like
12) Sub queries
13) CTE
14) Replace CTE with temp tables
15) Methods to optimize Sql queries
16) Solve problems and case studies at Ankit Bansal youtube channel
Trick: Just copy each term and paste on youtube and watch any 10 to 15 minute on each topic and practise it while learning , By doing this , you get the basics understanding
17) Now time to go on youtube and search data analysis end to end project using sql
18) Watch them and practise them end to end.
17) learn integration with power bi
In this way , you will not only memorize the concepts but also learn how to implement them in your current working and projects and will be able to defend it in your interviews as well.

๐ AI Terminologies Every Beginner Should Know (Part 2)
If you're learning AI, these are some of the most common terms you'll encounter. Understanding them early will make advanced topics much easier.
1. Dataset
A collection of data used to train, validate, or test an AI model.
Example: A folder containing 50,000 images of cats and dogs.
2. Training Data
The data used to teach an AI model how to perform a task.
Example: Thousands of emails labeled as "Spam" or "Not Spam."
3. Test Data
New, unseen data used to evaluate how well a trained model performs.
4. Features
The input variables or characteristics used by an AI model to make predictions.
Example: Age, salary, and years of experience for predicting employee attrition.
5. Labels
The correct answers or target values that the model learns to predict.
Example: "Approved" or "Rejected" in a loan prediction dataset.
6. Model
A trained AI system that has learned patterns from data and can make predictions or generate outputs.
7. Algorithm
A set of rules or mathematical procedures used to train an AI model.
Examples: Linear Regression, Decision Tree, Random Forest.
8. Parameters
The values learned by a model during training.
These determine how the model makes predictions.
9. Hyperparameters
Settings chosen before training begins.
Examples:
โข Learning Rate
โข Batch Size
โข Number of Epochs
10. Epoch
One complete pass of the entire training dataset through the model.
If you train for 20 epochs, the model has seen the complete dataset 20 times.
11. Batch
A small subset of training data processed at one time.
Instead of training on 100,000 records together, the model may process batches of 32 or 64 records.
12. Loss Function
A mathematical function that measures how wrong the model's predictions are.
Lower loss generally means better performance.
13. Optimization
The process of updating model parameters to reduce the loss.
14. Learning Rate
Controls how big each update is while training the model.
โข Too high โ Model may overshoot.
โข Too low โ Training becomes very slow.
15. Accuracy
The percentage of correct predictions made by a model.
Example:
If a model correctly predicts 95 out of 100 cases, its accuracy is 95%.
16. Precision
Out of all positive predictions, how many were actually correct.
17. Recall
Out of all actual positive cases, how many the model correctly identified.
18. F1 Score
A balanced metric that combines Precision and Recall into a single score.
19. Confusion Matrix
A table used to evaluate classification models by showing:
โข True Positives
โข False Positives
โข True Negatives
โข False Negatives
20. Prediction
The final output generated by an AI model after processing new data.
Example:
Predicting whether a customer will churn or whether an email is spam.

AI Fundamentals You Should Know: ๐ค๐
1. Artificial Intelligence (AI)
โ Technology that allows machines to mimic human intelligence like learning, reasoning, problem-solving, and decision-making. AI powers tools like Chat, recommendation systems, voice assistants, and self-driving technologies.
2. Machine Learning (ML)
โ A subset of AI where systems learn patterns from data instead of being manually programmed. The more quality data ML models receive, the better they become at predictions and analysis.
3. Deep Learning
โ An advanced form of machine learning that uses neural networks with multiple layers to process complex tasks like image recognition, speech understanding, and generative AI.
4. AI Agent
โ An autonomous AI system capable of performing tasks, making decisions, interacting with tools, and completing workflows with minimal human input. AI agents are becoming the foundation of next-generation automation.
5. AI Model
โ A trained computational system that processes inputs and generates outputs such as predictions, text, images, or recommendations based on learned patterns.
6. Training
โ The process where AI models learn from massive datasets by identifying patterns, adjusting internal parameters, and improving accuracy over time.
7. Inference
โ The operational stage where a trained AI model generates responses, predictions, or decisions for real-world use. Every Chat response is an example of inference.
8. Prompt
โ Instructions, commands, or questions provided to an AI system. The clarity and detail of prompts directly impact the quality of AI outputs.
9. Prompt Engineering
โ The skill of designing structured and optimized prompts to guide AI systems toward more accurate, useful, and context-aware responses.
10. Generative AI
โ AI systems capable of creating original content such as text, images, music, videos, designs, and code instead of only analyzing existing information.
11. Token
โ Small units of text processed by AI models. Tokens may represent words, parts of words, or symbols that help AI understand and generate language.
12. Hallucination
โ A phenomenon where AI generates false, misleading, or fabricated information confidently due to prediction errors or lack of verified context.
13. Fine-Tuning
โ The process of customizing a pre-trained AI model using specialized datasets so it performs better on specific tasks or industries.
14. Multimodal AI
โ AI systems capable of processing and understanding multiple data formats together, including text, images, audio, and video.
15. LLM (Large Language Model)
โ Massive AI models trained on huge text datasets to understand language, answer questions, summarize information, and generate human-like responses.
16. Neural Network
โ A computational architecture inspired by the human brain, consisting of interconnected nodes that help AI recognize patterns and make decisions.
17. RAG (Retrieval-Augmented Generation)
โ A technique where AI retrieves external or updated information before generating responses, improving factual accuracy and context relevance.
18. Embeddings
โ Mathematical vector representations of text, images, or data that allow AI systems to understand meaning, similarity, and relationships between information.
19. Vector Database
โ Specialized databases designed to store and search embeddings efficiently, enabling semantic search and advanced AI retrieval systems.
20. Agentic AI
โ Advanced AI systems capable of reasoning, planning, memory handling, decision-making, and autonomously completing complex multi-step tasks.
21. Open Source AI
โ AI models and frameworks publicly available for developers and researchers to access, modify, improve, and build upon collaboratively.
