Are you interested in a career in Data Science or Data Analytics? In that case, inevitably you are going to encounter databases in your work. But how do you interact with databases? The answer is simple: SQL! SQL stands for Structured Query Language and is one of the main tools used to organize databases, input data into them, and extract it upon request. In this course, you will learn how to create queries in a popular variation of SQL called PostgreSQL.

Even if your workplace uses a different variation (e.g., Oracle, SQL Server, or MySQL), the skills you learn in this course are easily transferable. But with many SQL courses available, you might wonder:

What Makes This Course Stand Out?

The unique advantage of this course is that, in addition to learning SQL, you will also master the concepts of Database Design.

Topics Covered

  • OLAP vs. OLTP Databases (Online Analytics Processing & Online Transaction Processing): You will understand exactly how and why the designs of these two types of databases differ.
  • Normalization of Databases: We will explain the theory behind normalization and practice how to normalize a database step-by-step.

Why Is Database Design Important?

  • While not mandatory for Data Scientists or Analysts, understanding database design is a significant added benefit.
  • This knowledge enables you to interact with databases more effectively and extract insights from your data faster.
  • Designed with Data Scientists and Analysts in mind, taking this course can accelerate your Data Science career.

About the Author: Udemy

Udemy thumbnail

Udemy is the largest open marketplace for online courses on the internet. Founded in 2010 by Eren Bali, Oktay Caglar, and Gagan Biyani and headquartered in San Francisco, the company went public on the Nasdaq in 2021 under the ticker UDMY. The platform hosts well over two hundred thousand courses across software development, IT and cloud, data science, design, business, marketing, and creative skills, taught by tens of thousands of independent instructors. Roughly seventy million learners use it worldwide, and the corporate arm — Udemy Business — supplies a curated subset of that catalog to enterprise customers.

Because Udemy is a marketplace rather than a single editorial publisher, the catalog is uneven by design. The strongest material lives in the long-form, project-based courses authored by working engineers — full-stack JavaScript, React, Node.js, Python data science, AWS, Docker and Kubernetes, mobile development with Flutter and React Native, and cloud certification preparation. The CourseFlix listing under this source is the slice of that catalog that has been mirrored here for offline-friendly viewing, organized by topic and updated as new releases land. Pricing on Udemy itself swings dramatically with the site's near-permanent sales, which is why the platform is best treated as a deep reference catalog: pick instructors with strong reviews and a track record of updating their material rather than buying on the headline price alone.
