Course Overview
Intro to Relational Databases course is a quick and enjoyable introduction to using a relational database from Python code. You will learn the fundamentals of Structured Query Language (SQL) and database design and how to use Python Application Programming Interface (API) to connect Python code to databases. You will also learn how to protect your database-backed web applications from common security issues. After completing this course, you can write code that uses a database as a backend to store application data.
Karl Krueger is the instructor of this course, which is beginner-friendly and has a detailed outline of a Relation database and how to use it
"Knowing about databases is essential and this course will teach you all you need to know about relational databases, so that you can do well in your career."

Course Structure
This is an online, self-paced certification course devised for beginners. It covers:
- Relational databases
- How can you access the table, write normal queries, or use complicated joins?
- How can use it in a programming language (Python)
- Tabled Structured data in Relational databases
- What is SQL, and how can we write queries to access the data in the tables?
- How can we use and interact with the database using Python in a Virtual Machine (VM) environment?
- How to use complicated joins and design the table for production usage
Insider Tips
To get the best out of this course, I have included some important tips that you might find useful.
Prerequisites
Make sure you have a basic understanding of CS terminologies (if not, we can take CS101) and know how to write code in Python. Python allows you to read and write basic code. Python programming exercises are used in this course. If you have never worked with Python before, take a look at ‘Programming Foundations with Python’ course.
Assessment
There were a few exercises for each topic to ensure that we understood the lessons well. We were assessed on the basis of online questions. Learners are allowed to take multiple attempts for the assessments.
Final Take
Taking this course gave me confidence about using Relational databases. I was able to use the knowledge gained in my career and side projects. I have taken many courses from Udacity, so I wanted to cover all computer science-related topics hence undertook this course as well.
I recommend taking ‘CS101’ program, which covers the fundamentals, before starting this course. ‘Introduction to Programming’ is another course which will help you take your first step toward a career in Web and App Development, Machine Learning, Data Science, AI, and other fields. It is an ideal course for newcomers.
Knowing about databases is essential if you want to pursue a career in full-stack development. Even if many toolkits hide database details from your application code, being able to interact with the database will help you design, debug, and maintain your applications.
