Course Description

In this course you will learn how to write and execute SQL queries on your own database. Starting with basic SQL, we will learn how to use PostgreSQL to make advanced data analysis, graphs, reports and tables. 


Who should attend this SQL and Data Viz course?

  • You who are dependent on Business Analysts to create Reports

  • You who are limited to Excel or Spreadsheet for your data analyses

  • You who would like to do some in-depth analysis and blow your boss or client away

  • You're the one who always said, "I need to learn SQL!"

  • You who find your business analysis dull and graphless.


Why learn SQL?

Whether you are a Marketer, Product Marketer, Developer, Sales or Manager, SQL is one of the most sought-after skills in the job market. This extraordinary skill takes your CV into another world, the world of autonomy and rigor in your reporting.

To learn SQL and Data Viz, you don't need to have a "Business Analyst" career plan. This skill will serve you in all areas, just like some tools such as Excel or Google Spreadsheet have served you well. The only difference? SQL is much more advanced than these!


Become an expert in data visualization

You'll learn how to become a business analyst and produce reports that are as visual as they are effective. In just a few clicks, create your own PostgreSQL database and connect the best tools to make your analyses dynamic, attractive and orderly. You can then create your own charts, histograms, curves and world maps for specific business situations.


Learn SQL from A to Z

SQL will have no secrets from you. Of course, we'll go over the basics. Then, you'll even become an expert as you get more and more powerful as you watch the videos.

CASE
       WHEN 'become better in analysis' THEN 'join this course'
       ELSE  'keep working on Excel'
END AS expert_sql_and_data_viz


The tools you will master

- Metabase, the perfect data visualization tool to run your data analysis
- Heroku, to host your database
- PGAdmin, to create your database and data set


Why is this course different from the others?

1- You will apply SQL in real business cases that you will be able to reuse
2- You will work on your own database
3- You will create your own graphs in a few minutes
4- You will progress step by step in the SQL language
5- I will answer all your questions in a few minutes

Anyway, I just wanted to tell you that I'm not from the Data world. I'm a Marketing Manager who got tired of doing his reports in Excel and wanted to take it to the next level by learning SQL! So, if I did it, you can do it.

So, join me in this course "SQL & Data Visualization: the complete guide", and don't hesitate to leave a note if you like this course ✌️

Hello,


I am Raffi Sarkissian, one of the co-founders of Lago, the no-code data tool for Growth Teams.

Previously, I was the Head of Growth Operations & Business Intelligence at Qonto, a 500-person fintech that raised €135 million in funding. I manage a team of 4 data analysts. This has allowed me to install or use powerful data visualization tools like Metabase or Tableau and to work on Postgresql databases or Warehouses like Snowflake. My expertise allows me to teach beginners the art of SQL and data analysis in a simple, fun and multi-step way:


1- Installing a database with PGAdmin, a data visualization tool with Metabase and a server with Heroku.

2- The basics of SQL3- Building graphs and BI dashboards for a first step in the world of data visualization4- Advanced SQL to meet business needs (cohorts, median, quartiles, series generation etc...)


Kind regards

Is a good course but the material is outdated and Metabase is no longer free. Did have to spin up postgress and Metabase locally using docker to complete the course. Other than that, the explanations are rather good and easy to understand

By Ana Carina Morales on 12/15/2024

Excelente!!! Muy claro en las explicaciones. Ampliamente recomendado para personas que usan SQL en METABASE, comienza desde lo básico hasta lo más complejo. Recomiendo mucho el análisis de Cohort.

By Bradley Cole on 12/11/2024

I'm working mainly in Metabase for data visualizations, and this was the most complete video I've found on the internet as far as training in and with Metabase is concerned. It is a bit dated but overall a good source to watch. Much appreciated!

By Guy Crumpley on 3/17/2023

Installation instructions for pgAdmin 4 could be smoother (note the failed installation of version 10 in the wizard). Need to provide a free option for running the software -- Heroku now requires a paid subscription.

By Carlton Walton on 11/29/2022

This information is outdated. You will spend considerable time figuring out the set up. There are now paid components that users should be aware of. Once you get through that, you should be able to get on your way. Please note, it appears that when you set up the payment method during the initial deploys, I think it has to be the first of the month, otherwise it's not recognized.

By Anonymized User on 8/20/2021

Nevertheless 14 days free trial, in order to get Metabase account you need to enter your payment card's data. It would be much better to use any other visualization platform which doesn't have such kind of constraints

By Amitkumar Agarwal on 6/14/2021

The course was very comprehensive and easy to understand. The instructors made sure that they are giving the information in a way that won't make me confused. Thank you so much for this great course! Thank you Raffi.

A forma com que o curso é apresentado é fantástica. Tudo é visto com muita calma e, por vezes, se você tentar fazer o que o instrutor disse que vai fazer, você sente o aprendizado. Contudo, tive alguma dificuldade na parte de configuração. Algumas telas que ele mostrou não apareciam para mim. Tive que pesquisar como fazer.

Great Course. Loved the way the course is structured. The pace of the course is perfect. Would love to recommend to everyone who wants to learn Visualization using SQL query.

By Kino Davis on 7/5/2020

This is an amazing course! I like(ed) to think that I am pretty good with SQL, but I did learn a lot in the course. Metabase is an awesome tool and Raffi is incredible with his knowledge of Metabase, SQL and Data Visualization. The first part of the course covers setting up Metabase and pgAdmin and Raffi focuses on Mac for this but it is pretty easy to get through with Linux. Even if you already know SQL, I suggest watching the lessons anyway... picked up a couple of things there! The only thing was tough for me is that (for me) there was a little problem understanding what Raffi is saying and he moves fast! I had to pause and/or go back in the videos pretty often, but as things went on I started to pick up what he was saying and it smoothed out nicely. I highly recommend the course and I will look for other courses from Raffi.
