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.

This course covers all of the basics in mySQL and Teradata for successful data analysis using sql. I found it challenging but very explanatory while exposing you to common difficulties in the real data world.

The course is very well calibrated. You move step by step from easy SQL queries to pretty complex ones. The connection to the business value of the queries you write is also explained in a convincing way.

Well-structured and well-organized course. Probably the best SQL course I have ever seen. Special thanks to Dillard´s store chain and Dognition for giving an opportunity to work with real business data.

Generally very good experience. The course is tough, but absolutely helpful and rewarding. Supportive as I am, I do hope instructors could update the course materials and correct the mistakes within.

Very well structured course. Not that difficult as i thought but it did take me much more time than I expected. You'd better focus on learning for several hours instead of using short time slot.

very detailed introduction of SQL. The only thing is that there could be more videos introduce different functions instead of writing documents as materials. Other than that, it's a great class

Great course to go deeper into SQL. Very good teaching style and realistic learning tasks. It was sometimes difficult to use two different environments, but it is real life. Thanks to authors!

Not only it teaches you how to use MySQL and Teradata in a technical perspective, it also practice the analytical mind and how you would treat a real life dataset when doing analytical work.

The exercises and quizzes (particularly the teradata sets) were difficult enough that you have to think and structure your approach to arrive at the right solution. Very good learning curve.

Excellent course for beginners looking to be able to utilize SQL directly or even understand how SQL works so requirements can be gathered with greater detail and why that detail is needed.

MySQL lessons, quizzes and assignments are very well organised and taught. But was not very happy with the Teradata part. Overall it was a very good course! Jana is a fantastic teacher.

Great course indeed. I read a few negative comments about extensive exercises, but that is the beauty of this Course. These exercises make sure that one has fully grasp over concepts.

it was an amazing experience with MySQL and Teradata. I have learned a lot of detail information on how to create a query, and I hopefully can use this knowledge in my future career.

Excellent introduction to SQL if students take the extra time to do the optional exercises and really get comfortable with the SQL syntax and nuances. Engaging and also challenging.

Very practical and challenging! However the Teradata content is much more overwhelming than the MySQL content due to its format (MySQL parts were explained thoroughly in Jupyter).

This is an excellent course indeed. Access to real world data is a huge +. Some of the questions in the quizzes were difficult though. And also the witty jokes by the Prof... :):)
