SQL Essential - Basic Concepts | OLTP vs OLAP Database Design Systems

Welcome to my SQL tutorial! 🎉
In this video, I'll dive into the differences between OLTP (Online Transaction Processing) and OLAP (Online Analytical Processing) systems and their respective uses. Whether you're a beginner or simply curious about a career in data analytics, this is the perfect place to start!
🔍 What You'll Learn:
1. Understanding OLTP: Discover what OLTP is, its main characteristics, and typical use cases such as handling real-time transactional data in e-commerce platforms.
2. Understanding OLAP: Learn about OLAP, its features, and how it is used to perform complex analytical queries on large datasets, ideal for data analysis and decision-making.
3. Comparing OLTP and OLAP: We'll explore the key differences between OLTP and OLAP systems, focusing on data models, operations, and performance considerations.
4. Usage Scenarios: See practical examples of when to use OLTP versus OLAP, and how they complement each other in a comprehensive data strategy.
5. Database Design: Introduction to normalization in OLTP and denormalization in OLAP, including techniques like Star and Snowflake schemas for improving query performance in analytical databases.
6. ETL Process: Understand the role of ETL (Extract, Transform, Load) in transferring data from OLTP to OLAP systems to leverage the strengths of both.
