SQL & Database Design A-ZTM: Learn MS SQL Server + PostgreSQL

Considering a career in Data Science or Data Analytics? You'll quickly discover the importance of databases! Understanding how to interact with them is crucial, and that's where SQL comes in.

SQL (Structured Query Language) is the standard language for managing databases: organizing data, inserting new information, and retrieving specific data sets. This course focuses on PostgreSQL, a popular and powerful SQL database system. While you might encounter other variations like Oracle, SQL Server, or MySQL in your professional life, the core SQL skills you gain here are highly transferable.

So, what makes this SQL course different? Beyond just learning SQL syntax, you'll also master the fundamentals of Database Design.

Here's what you'll learn:

• OLAP vs OLTP Databases: Understand the key differences between Online Analytics Processing (OLAP) and Online Transaction Processing (OLTP) databases. Learn why their designs diverge and how to choose the right database type for your needs.
• Database Normalization: Grasp the theory behind database normalization and, most importantly, practice applying it step-by-step. We'll guide you through the process of normalizing a database, ensuring data integrity and efficiency.

Why is database design so valuable? While not always a mandatory skill for Data Scientists and Data Analysts, it provides a significant advantage. Strong database skills empower you to:

• Interact more effectively with databases.
• Extract insights from your data more quickly.
• Derive more accurate and meaningful results.
