課程概述

This course is an introduction to how to use relational databases in business analysis. You will learn how relational databases work, and how to use entity-relationship diagrams to display the structure of the data held within them. This knowledge will help you understand how data needs to be collected in business contexts, and help you identify features you want to consider if you are involved in implementing new data collection efforts. You will also learn how to execute the most useful query and table aggregation statements for business analysts, and practice using them with real databases. No more waiting 48 hours for someone else in the company to provide data to you – you will be able to get the data by yourself! By the end of this course, you will have a clear understanding of how relational databases work, and have a portfolio of queries you can show potential employers. Businesses are collecting increasing amounts of information with the hope that data will yield novel insights into how to improve businesses. Analysts that understand how to access this data – this means you! – will have a strong competitive advantage in this data-smitten business world....

Nice and well-organized course. I joined this course after self-studying on SQL for a few days. The context is really nice. The only problem is the Teradata is not stable. I tried very hard to login.

I found the first 4 weeks of the course amazing: just really well structured, thought-out, and delivered in a way that positions the student for success. Jana breaks the material down into digestible bits, gives you sufficient practice, and even if you don't get it, you can look at the answers to the practice questions and figure out where your thinking was incorrect.

The 5th week wasn't as well broken down, especially the last set of Teradata exercises. New concepts or ways of structuring queries were being introduced in those exercises, but there was no way to check for a correct solution if I couldn't come with one on my own (which was unfortunately half of the time). I still got a good grade on my last quiz, but I can't say that I really truly learned how to write the more complicated queries.

I would suggest that the last Teradata exercise set has more explanation or perhaps just answers that the student can refer to in order to understand why his/her line of thinking isn't working.

Otherwise, a truly fantastic course. I 100% recommend it.

This course really touched on all the most important aspects of learning how to use a SQL database while also providing many supporting materials for reference. I was very satisfied with the quality of the materials and teaching.

If you work with data this is an excellent course, but even if you are not a frequent data user you can learn a lot from the logic it explains. I absolutely recommend it.

Best course to start learning SQL & Jupyter Notebook (Python). I have already tried to learn SQL from CodeAcademy, but this one is much more intuitive & detail-oriented. Lots of easy-to-follow examples, great instructor and quality of videos/lectures. I recommend it 100%.
