Course Description

IMPORTANT NOTE: This is an advanced SQL course, which builds on the skills covered in our introductory MySQL courses. Please review the prerequisite skills or complete the beginner SQL course before taking this one!


If you want to develop practical, real-world database analytics & business intelligence skills using advanced SQL, you're in the right place.


This course is unlike anything you’ve seen before. Instead of using random sample data and obscure demos, we’ll be working with a rich, custom-built ecommerce database that we’ve designed from scratch to help you apply your SQL skills to real projects and learn how to truly THINK like a data analyst.


You’ll be playing the role of a newly hired Database Analyst for Maven Fuzzy Factory, an eCommerce start-up, and will be working directly with the CEO, Marketing Director and Website Manager to help grow the business and analyze performance along the way. You'll use a range of advanced SQL tools and techniques, and work through actual projects that data analysts and business intelligence professionals work on every day.


COURSE OUTLINE:


  • Prerequisite SQL Skills Assessment

    In this section we'll address the core SQL/MySQL skills that you should be comfortable with before starting the course, including SELECT statements, aggregate functions, and table joins. If you aren't sure how your skills stack up, we've included a quiz to assess your baseline SQL knowledge.


  • MySQL Setup & Install

    For students who haven't completed our intro course, we'll demonstrate exactly how to download and install the tools that we'll need to access MySQL, including MySQL Community Server & MySQL Workbench. We'll share download guides for both Mac & PC, and run our first piece of SQL code to generate the project database that we'll analyze throughout the course.


  • Traffic Analysis & Optimization

    In this section we’ll use MySQL to analyze where our website traffic is coming from, how different sources perform in terms of traffic volume and conversion rates, and how we can adjust bids to optimize our budgets.


  • Website Measurement & Testing

    In this section we'll dive into page-level website data to compare traffic and conversion rates, and use MySQL to build and analyze conversion funnels to help optimize the customer purchase experience.


    *MID-COURSE PROJECT: Preparing data for the executive board meeting


  • Channel Analysis & Optimization

    In this section we’ll dig deeper into our traffic channel mix, explore paid vs. free traffic, break down performance by device type, and write advanced SQL queries to conduct some time-series analyses to understand trending and seasonality.


  • Product-Level Analysis

    In this section we’ll use MySQL to break down product-level sales and conversion rates, analyze cross-selling patterns, and use refund rates to keep a pulse on quality.


  • User-Level Analysis

    In this section we’ll take a closer look at user behavior and repeat sessions, and use MySQL data analysis techniques to identify our most valuable customers and explore which channels they are coming from.


    *FINAL PROJECT: Building a data-driven growth story for potential investors


Unlike other SQL courses, this one is uniquely designed to sharpen your business intelligence and analytical thinking skills; as you complete course projects and exercises, you’ll actually see patterns and trends emerging in the data based on your findings. For those looking to pursue a career in analytics, this course is a must.


Enroll today and get LIFETIME access to:

  • 8+ hours of high-quality video

  • Downloadable MySQL ebook

  • Quizzes and hands-on projects

  • Mid-course and Final SQL projects

  • 30-day money-back guarantee


IMPORTANT NOTE: This course does NOT cover building, altering, or maintaining SQL/MySQL databases. Our goal here is to focus on data exploration and database analysis using MySQL and MySQL Workbench (we'll cover database administration tools in a separate course).


Happy analyzing!

"I totally loved this course! Everything was easy to understand, but it moved at a fast enough pace that I never got bored. I learned SO much about MySQL and had fun doing it. In fact, at the end of the day I didn't want to stop learning -- I wanted to keep charging on to the next lesson!"

- Ann S.

"This is an excellent advanced course! I've taken both SQL courses from Maven Analytics and highly recommend both. The best part of this course is the detail they included by building a real world e-commerce database. It's much easier to grasp the concepts when you can see how they're literally applied to scenarios and outcomes as opposed to just theory. Great work!"

- Dan S.

"John's deep understanding of SQL and database analysis and ability to explain those tools is really unmatched. I've taken other SQL and MySQL courses and tried reading books, but this course is by far the most effective. Excited to see more courses from John!"

No advanced topics covered here, merely rephrasings of different business contexts. Videos and assignments simply cycle through the same few techniques—specifically elementry CTEs and pivoting with COUNT(DISTINCT CASE) pattern.

By Anson Tan on 5/5/2023

The course is very well-made for you to apply your SQL knowledge to projects that are very similar to some real-world scenarios. It is very practical and you can learn some useful and advanced ways to navigate the business world as a data person. I would really like more of such courses to see how other people come up with solutions for business problems, as I believe it is very useful to learn from them compared to just me trying to spend so much time to solve them by myself all the time.

By Ufuk Kadir Ergin on 9/10/2022

This is a great advanced course and John is an excellent instructor along with the teaching assistants here. Not only the topics are very relevant, but also John and the course TAs are very quick and helpful in answering your questions. If you are looking for an advanced SQL course, you should definitely purchase this. I wish he included window functions in the course as well. I hope he considers including this topic as well.

By Lee Duffy on 2/3/2021

For me, the material presented in this course was well delivered and presented with plenty of opportunity to utilise the skills/concepts John demonstrates. Not being familiar with website traffic data, I would have liked to have seen a short video explaining the traffic types (organic, paid etc) so that it could be easily referred to when needed, without having to search for the couple of videos which mention it. Still worthy of a 5 star, as the learning and skills you can derive from this are worth much more that the price of the course.

Kudos to Maven Analytics team that curated excellent syllabus. And a special thanks to John Pauler for actual projects underpinned by real-world eCommerce database and the help when I was overwhelmed by error and underlying business concepts. I had to go over 'multi-step queries' several times to really get the hang of it. So rewarding is fair amount of coding for analytic tasks! My next challenge is DB administration course from John.

By Rizky Akbar Maharoesman on 12/22/2020

Good course indeed, very valuable to your money too. Although some assignment above my knowledge (new user to MySQL) especially from section 80 to 90 but the explanation in solution video really helps me to understand. Tips, for those who may want to try this course: sometimes you need to find solution by yourself through search engine but that's part of study to so it's all right, keep grinding and trying. and, If you expect to find course that challenging and broaden your knowledge about MySQL, this course is the right place.

By Rajshekhar Paul on 8/26/2020

The only thing which stops me from giving a perfect 5 is the absence of the application of windows function, user defined function and string function. While the course is an excellent source to understand website analytics and the different aspects of it, SQL can get a little better. When you read advanced SQL, you expect tricky string functions to manipulate strings and different usage of windows functions, since both these functions are extremely important for data analytics.

By Innocent Dike on 8/21/2020

This course has been very challenging but it has broaden my knowledge more on advance analysis thank you guys very much for offering this course I look forward to doing another course that interest me from you guys and that has to do with real life work. My recommendation is that going towards the end of the course the explanations became hard to follow due to less explanation especially on those difficult one. It would be nice to break them on a step by step basis continuously for easier understanding. Moreover, this is an AMAZING course and a GREAT instructor. Thank you very much John, you are AMAZING!.

By Sivaranjani on 7/26/2020

A wonderful course. Satisfied a lot and Highly recommend it to all. Well structured, high quality videos and wonderful teaching ability by John. Quick responses for my questions everyday , that's why I was able to finish and learn the course . Would recommend maven analytics to go through the comments we make in your announcement section. Many of us have placed a request for another Advanced level course like this with another business model. Anyways thanks a lot for this course.

By Ankur Sharma on 2/13/2020

Note: This is My 1st course on SQL. Hence, I do not have any benchmarks. This Course involved Practice, Practice and Practice. With so many Assignments, this Course ensures the Learner will thoroughly grasp the Concepts. AweSome! Thank You, John! You were super prompt to answer My queries. Your support and encouraging words were very, very reassuring. Gratitude!
