Course Description

Master PostgreSQL and use it in your Python apps!

Python and PostgreSQL are two of the most in-demand skills in the world. After completing this course, you'll be confident in adding both to your resume/CV.

Everything you'll learn in this course is relevant to other database systems too, like MySQL, Microsoft SQL Server, or Oracle.

With this course, you'll master PostgreSQL and how to work with it from Python. If you use Python and you want to augment your skills with a database, you'll love this course!


You will:

  • Work with different types of databases (in-memory, SQLite, and PostgreSQL), and understand when to use each in your Python apps.

  • Build a programming journal project to add a SQLite database to your Python application.

  • Improve a database design incrementally so you're not bound by your initial design.

  • Model different relationships with PostgreSQL, including one-to-many and many-to-many.

  • Reduce errors by applying database changes using database migrations with Python and alembic.

  • Build a polling app to learn about advanced data analysis with GROUP BY, PostgreSQL window functions, and nested queries.

  • Work with dates and times in PostgreSQL, and avoid common timezone pitfalls.

  • Structure Python apps like a professional, to make development much easier.

  • Produce data analysis reports and charts using matplotlib with PostgreSQL data.


You'll also tackle advanced PostgreSQL topics, such as:

  • User-Defined Functions

  • Stored Procedures

  • Locking

  • Async database connections


As you can see, you're going to learn a lot!

But this is a no-nonsense, no-frills course. We have planned, crafted, and edited every lecture to be concise and compact. No time wasted, so you can master PostgreSQL in record time.

We've created dozens of diagrams to explain database concepts, as well as code-along videos. But you won't just be watching me code! You'll develop the projects yourself first, to gain hands-on experience and master PostgreSQL.

Also, throughout the course, I provide data sets with challenges and exercises for you to practice what you've learned.

I've been teaching and helping students online for over 8 years, and this course is the culmination of my teaching experience. I know how to help you understand concepts fully and quickly, in the best way for you.


When you complete this course you'll be able to:

  • Extend your Python applications with database functionality using PostgreSQL.

  • Answer complex questions using data and generate reports.

  • List PostgreSQL as one of your strongest skills.

As per the course going on it's becoming more interesting and exciting . The productiveness of this course is truly praiseworthy and purchasing this course is really worth it...If you are bit familiar with the python language (talking about just basics) then this course is really made for you although the the python refresher is quite enough to proceed further. And the level of content in postgreSQL part is just sky high ..love this content❤️❤️❤️

By Thomas Schneidewind on 12/22/2023

Highly qualified, motivated, cooperative and friendly instructor Structured and purposeful learning content Inspiring, animating and useful course matter Spirit of the time and applied informatics Theory and learning by doing highly appreciated Programming as fascination, transmitted from this course Many thanks for this unique opportunity

By Tamás Király on 4/20/2023

The delivery and the technical knowledge of the tutor is really good, everything's clear and understandable. However I was expecting a bit more of PostgreSQL specific SQL materials. Also I don't get why was it necessary to include a 1-hour-long Matplotlib section as the closing section of the tutorial.

By Jorge Ricardo Escobar Carrasco on 2/9/2023

Really useful for people that already know Python and Postgresql. In my case, I do know python and SQL but my gap is PostgreSQL itself. The RANK() and OVER() functions are new to me, I haven't seen them in any other database engines I worked with. So I think I will buy a PostgreSQL course and fill that knowledge gap next. The last chapter is really good introduction to creating plots and graphs from data visualization. Really good course, and is still relevant.

By Aryeh Kellman on 12/30/2021

With more than 20 years' experience in the field, it was very helpful to learn only the syntax for Python, instead of a complete programming course. As noted in the course, the basic elements of PostgreSQL are similar to other flavors of SQL. Again, this was very useful for me. I particularly liked the later sections of the course which incorporated and demonstrated the interaction between Python and PostgreSQL, as well as charting data. Well done.

By Pieter van der Merwe on 12/10/2021

I really learned a lot during the course, thanks a lot! Just a note, some of the code in section 9 of the e-book does contain some errors. So you have to keep one eye on the code shown in the video and the other on the code in the e-book just to make sure the code runs well.

Wenn man von JOIN-Select auf Select auf eine Tabelle und dann auf dem Ergebnis ein Scghelife druckläuft, kabnn das ein inkonsistetens Ergebnis leifern. Auch Uhrzeiten von den Clients statzt vom Datenbankserver zu benutzen kann zu Problemen führen. Es wäre gut wenn der Autor nit einer Ergänzung auf das Problem hinweisen würde.

By Gngr Demirhan on 11/22/2020

This course is sufficient for pre- intermadiate level. The involve detail knowledge and good thing.

By Ruslan Svirschevski on 11/22/2020

Good for PostgreSQL basics. I expected more of SQL stuff, but 30-40% of the course was Python basics and plotting. Also some more interactive homework would be nice.
Instructor is very good. Clean speech with right tempo. Surely knows his subject.
The ending is kinda abrupt. Pls add some learning path suggestions.

By Daniel Musser on 11/15/2020

I am only in the first few lectures but so far, I am pleased. I appreciate the instructors pace and how he explains things. Looking forward to learning all the course material.

By Opolot Martin on 11/15/2020

Wow Wow, Wow, is there a way we can get more on translating this into graphical applications? But this has been the best so far I have gained in python.

By Stefano Ferrari on 11/8/2020

Very useful. Clear explanations and very interesting subjects.
