Database structure design?  It's here.  Query tuning and optimization? You'll master it.  Complex queries? Yes indeed.

This is the only course online that will teach you how to design a database, store complex data, optimize your queries, everything that is needed for operating a production, scalable database.

Every app in the world, whether it is a mobile app built with Flutter, a web app constructed with React, or a plain HTML page, needs to store information in a database.  Although there are many different databases you can use, PostgreSQL has been a number-one pick for decades, offering scalable performance, rock-solid uptime, and flexible design systems.  This course will teach you everything you need to know about PostgreSQL to use it on your next big project.

Don't know anything about databases at all? No problem. We begin with an overview of SQL, the language used to interact with PostgreSQL. Through an incredible number of exercises, you'll get practical, hands on experience working with realistic datasets.  You will understand how to store, fetch, and update information with a series of powerful commands. 

After gaining experience with elementary operations, you will move on to understanding database design patterns, offering multiple ways to structure your database for efficient data modeling. You'll see many different scenarios with different types of data, and understand the pros and cons to several approaches.

This course is packed with practice exercises and quizzes. You'll get immediate practice on all of the different topics and features that you learn.   In addition, you'll understand exactly where to use each of these features in real and practical projects.

Besides getting practical hands-on experience, you'll also get a behind-the-scenes look at how PostgreSQL works internally. We'll dive into raw data files, investigating how PostgreSQL stores information on your hard drive bit by bit.  This knowledge is invaluable when it comes time to start tuning your queries for performance.  By having a natural instinct of how PostgreSQL works, you can plan on being able to get every last bit of performance out of your database.

Here is a partial list of some of the topics that are covered in this course:

  • Apply powerful SQL commands to store, update, and retrieve information

  • Build relationships between records using foreign keys between tables

  • Understand PostgreSQL's numerous data types, and when to use each

  • Assemble reports of business data by using aggregation pipelines

  • Work with millions of records to simulate real production queries

  • Exercise your query logic skills through the use of sets and sorting operators

  • Compose queries out of smaller reusable units using subqueries

  • Use different design patterns to efficiently model your data

  • See how to divide database objects into different schemas to maintain them more easily

  • Validate your data using simple 'check' rules

  • Construct perfect designs for common features such as 'like', 'follow', and 'tag' systems

  • Speed up your queries with indexes - you'll see exactly how they work behind the scenes.

  • Dive into some of the most complex queries around with recursive common table expressions

  • Deal with concurrency issues easily by applying transactions

I made this course to be the perfect resource for engineers just getting started with their first database.  Master the database itself, and see how to apply it with real designs.  Sign up today and master PostgreSQL.

Reviews summary

Postgresql and sql: deep dive

learners say this course is a largely positive and engaging introduction to databases for beginners, especially those with a programming background. It covers a wide range of topics and provides hands-on exercises to reinforce learning. The instructor is praised for his clear explanations, use of diagrams, and enthusiasm.
This course covers a comprehensive range of topics related to SQL and PostgreSQL, from basic concepts to advanced techniques.
"This might be one of the greatest courses on SQL I have taken. The instructor does a great job visualizing the SQL code operations, materialising all those abstract concepts."
"This is a very useful course. Stephen goes from talking about basic SQL, to writing advanced queries, to looking at the internals of Postgres, to integrating Postgres into a web app. Explanations are both clear and thorough, with lots of examples and helpful diagrams."
Learners appreciate the instructor's engaging and enthusiastic teaching style, which makes the learning process more enjoyable.
" Stephen Grider does an outstanding job of explaining Postgres VERY well. This is a beginner to intermediate course, so don't expect high-level DB administration info from this course. But, if you're new to Postgres, this course offers value in spades."
"Stephen teaches very well, love his style, I do feel this course could have touched on more PG specific areas like arrays, json, blob, geospatial data and text search, Gave it 5 stars because of the awesome teaching style, if only a bit more of these topics were included, but overall very solid."
This course is well-suited for beginners who are new to SQL and PostgreSQL, providing a comprehensive and easy-to-follow introduction.
"This course proved to be incredibly beginner-friendly."
"The way he puts things in his lectures are systematic and easy to digest."
This course features hands-on exercises and quizzes to help learners practice and reinforce their understanding of SQL and PostgreSQL.
"I really like the course so far. However, this last chapter where we are designing our database model is quite challenging. But it is maybe just me, I need to work a great deal further on this topic, as I am not familiar with Instagram at all. But I refuse to be discouraged and will stick to this course which overall is very good."
"Stephen is just synonym of excellence. Very well explained course where you gain a lot of valuable knowledge. Pay special attention to the use of graphs and charts, they really add to the learning experience. Not everything is hands on, the graphs and charts really help understand the big picture most of the time."
Stephen Grider provides in-depth explanations and insights into SQL and PostgreSQL, making complex concepts easy to understand.
"Stephen Grider adequately captures the nuances in all queries covered in this course (which is about all the important queries/keywords used in today's business world) giving an instance/problem which gives rise to the subsequent query."
"The instructor did an absolutely fantastic job at explaining the basics well, and the course moved from there to advanced topics with many solid practices & quizzes in between."
