About the Course

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....

One of the best course till now I find on Coursera, well structured everything and practice questions made me feel like real life problems as data were from real database of dognition and ua_dillards.

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.

As of June 2020, don't waste your time. This course is now useless since the third-party tool used by this course to open the Jupyter Notebooks is a dead link in the Duke University's server. There was an error processing this request: No jupyter instance available.

I​ wasn't able to complete the course, and as result the specialization because there was no way to access to the dataset required the course and no avenue for resolving the access issues which appeared to affect many learners in the course.

The course content is good, BUT the course administration very poor. They run out of license keys for the tool required to complete the course, so basically you have to keep paying the monthly fee without being able to complete the course.

Pathetic Course. So far the worst course of the entire specialization from Resource Support POV. The explanations given were far too complicated to understand as per me. Highly dissapointed. Also, Teradata was always a mess

It is very interesting, but we have to face problems with Teradata, I have not been able even to log in, and a lot of students are in the same situation, and the problem persists, even in the duedate of the test.

Quizzes are too advanced for a beginner course. Recommend to have simpler quizzes and the option for tougher questions in a more advanced course.
